Simgot EN700 BASS - One of the most natural sounding IEMs at fair price

by - July 04, 2017

Simgot EN700 BASS - Simgot brings a very interesting IEM to be the contender of the "Best ~100$ IEM". Sporting a natural sound and a large soundstage, EN700 Bass makes a great experience to listen to!


Simgot EN 700 Bass is one of the latest well-priced In-Ear Monitors (IEMs) produced by the new Chinese IEM producer Simgot. Being rather new in the industry, Simgot started making name for themselves with the release of their EN 700 IEM which has been described by many to have a natural sound along with a comfortable fit and a solid build quality.

I didn't know a lot about Simgot before writing this review, but in the short time I spent with them and their products, the company has left a good impression as they seem to be quite friendly. Simgot seems to be very proactive in answering their customer's questions, and in solving any issues that may arise, as well as offering support and advice to their customers.

Simgot EN 700 Bass is a tweaked version of the original Simgot EN700, the Bass edition sporting a new, more natural sound.

Simgot is just starting to make an appearance in the audiophile community, but they expressed a strong desire to communicate more with their customers and fans. EN700 and EN700 Bass are available for purchase from a multitude of shops, including Amazon, Aliexpress and if I'm not mistaken, there are Massdrop editions of EN700 around as well.

I have absolutely no affiliation with Simgot and I am not receiving any incentive. My review will be honest and objective, the purpose of it is to describe the sound and experience of EN700 Bass. My opinions are mine and I stand by every word I write. The review sample is provided by Simgot for my honest thoughts and feelings and Simgot insisted that I post everything I feel honestly and without sweetening things out.

About me

My name is George Dobrescu and I am the Director of the Seventh Heart Studios game studio. I work as one of the main programmers for the company, and I am the writer for Quantum Magica and Falsetto Memories projects. I spend eight – twelve hours a day working on a computer, writing and sometimes drawing. I also take care of administrative work which means that I require a portable setup so I'll be testing the portability of iDSD as well.

Music is present all around me for a big part of that time as working with music is always more fun. With all the devices I own, I need great sound, comfort and ease of usage, not to mention that my listening volume ranges from "please stop that, it's far too loud" to "I can't even tell that you're listening to music".

My collection includes everything from Classical to Metal, from Rap to Pop, from Punk to Cabaret and absolutely everything in between. There are great artists from every type of music, and I'm one to collect their albums, and keep a tidy order for my files.

You can check out more about our games on our pages     and .

At Seventh Heart Studios, we all love music and this has had an impact on our games as we hold the music close to our hearts and we are committed to only use ogg -q10 as the encoding format for our music since it offers the best disk space to sound quality ratio, OGG -q10 being closest to audibly transparent when compared to FLAC encoding. 

First Impression

When it comes to In-Ear Monitors (IEMs), I have owned a Sennheiser ie800 for a long while and I recently got a FiiO F5, Sennheiser M2 IEBT, and Dunu DK-3001 as well. Sennheiser ie800 has proven to be my longest-lasting companion, but Dunu DK-3001 is becoming more and more important in my daily listening. Both ie800 and DK-3001 make excellent benchmark IEMs and I am always on the lookout for more IEMs, Headphones and devices that would make an excellent benchmark in sonic qualities.

I was browsing the internets during a lonely night after work, when I noticed banners and photos carrying images of an intriguing IEM – an over-the-ear IEM, with an ingenious looking outer plate that reminded me of Audeze headphones. It piqued my curiosity and I started reading more and more about it, being more and more impressed by the overly positive feedback coming from the fans and customers.

Soon after, I started talking with Mr. Andrew Wang, the CEO of Simgot, and I posed many questions about the intricacies of EN700 and their products. I must commend Mr. Wang for finding proper solutions to my lots of quandaries and for his nice attitude during our conversations.

Simgot EN700 Bass arrived after about three weeks from the moment I spoke with Simgot, and this time it arrived through the Romanian postal service. It was a hot and dry day when I went to pick up EN700 Bass package. I was carrying lots of paperwork in my backpack and had quite a busy schedule that day, but I still found time to pick EN700 BASS from the postal service.

The weather in Bucharest can get insanely torrid in this time of the year, but it was not yet quite the 40 C Summer that Bucharest offers during July. Still, the sun felt more like a death-star rather than a warm friend in the sky.

The postal service is a good few minutes of walk from where I live, but I prefer to take a walk there since it is good for the health and I like to admire the iconic historical structures of Bucharest during the walk. The road leading to the postal center also goes near field where kids gather to play sports and I find it refreshing to see youth and energy once more, sometimes thinking to myself that we age way too fast and that sometimes we forget how to be young. The old postal service center is a reminiscent building of what was once a great community, built in Romania by the communist regime. Now it is only a relic, visited from time to time by those in need of a quick and cheap solution, but nothing there can reflect its former glory. The people there are usually nice and don't cause as many problems as TNT or DHL do, but if you don't pick a package on time, they send it back to the original sender…

I embarked on a transcendental few minutes of waiting in line with other people as there are too few agents working at the postal service nowadays. It is quaint to see a public postal service, everyone minding his own job, some sending packages, many paying things, and a few just being there to ask questions. The postage agent was very friendly and handed me the package quickly after signing some papers and presenting with the necessary papers.

Simgot has been careful with their packaging and wrapped it in quite a bit of bubble wrap, preparing it for your typical postage shipping conditions.

I went ahead and dealt with the paperwork that was in my backpack, the business being rather urgent. By the time I got home, it was already evening. It was complicated to eat or continue working when something so well-renowned was sitting on my desk, just waiting for me, inviting me to give it a listen, so I put my work to a hold for a few moments, so I could see what the hype was about with EN700 Bass.

After unboxing a rather good-looking package that includes a few rather unique accessories, I placed EN700 Bass in my ears, plugged them in iFi iDSD BL, our benchmark DAC/AMP and pressed play.

When trying them for the first time, I made a little mistake and tried using EN700 BASS with the smallest rubber tips included. It soon became evident that my ears needed the medium tips so I switched them over and started listening.

The sound I heard was intriguing and magical, EN700 BASS being one of the most natural IEMs I heard in their price range. I had to listen to them much more before I could pronounce myself about their sonic abilities.


First things first, let's get the packaging out of the way:

First time opening Simgot's package is an experience full of surprises. The design is simple but elegant, the main package being white and reminding of the typical art and packaging Apple products have.

The front of the box presents Simgot EN700 BASS IEMs in their beauty along with the company's logo, the sides of the box present photos of the cable, while the back of the box includes a photo of EN700's internal composition along with a few technical details about them in Chinese. It looks like Simgot offers a process of identifying their IEMs for authenticity as well.

After removing the first white cover, you will find a black cardboard box that has a nice texture-pattern over it, which has a bird-like creature engraved along with the name "Suzaku".

The cardboard box is padded with a fine sponge that protects EN700 Bass, which are seated in hard cardboard cutouts.

One of the most interesting accessories EN700 Bass offers is the leather-like case, which comes in brown color.

The carrying case looks unique and offers a good amount of protection for EN700, being hard on the sides and impossible to bend. The inner part of the case is also padded with a fine material that further protects EN700 Bass during transport.

On the back of the case, there is an interesting logo "Salute to Art and Science". I like their slogan and find it an interesting way to advertise their products. The packages and papers include something that I appreciate, which is a short table of what is the longest recommended exposure to each kind of loudness.

It is important for companies to remind their customers that listening to music at loud volumes for extended periods of time might lead to hearing problems.

The box also includes tips for EN700 bass, six pairs in total, a global warranty card, a brush for cleaning EN700, EN700's booklet and EN700 BASS themselves.

All in all, EN700 is packaged well and looks very good for its price range and the unboxing experience is a real pleasure.

What I look in for a IEM

When buying an IEM, there are a few things that a buyer should be looking and seriously consider as sooner or later those will come in foresight:

-      Sound quality – This is the most important aspect of an IEM by far, if it sounds good, it'll bring a lot of fun and pleasure to you

-      Ergonomics – the fit and ergonomics of a IEM are very important, the listener wants a comfortable IEM that can stay in place for hours at once and that doesn't have a microphonic cable.

-       Value – Some IEM fans might want to keep the value of their purchase in mind

-      Drive-ability – Some might want to drive an IEM directly from a smartphone or from a weaker source, it is important to know how hard or easy to drive is a IEM or Headphone before making a purchase

-      Interesting design – Everyone will have a different definition for what an interesting design is, but it is always good to see effort going to the design part of the IEM.

-      Portability – An IEM should be portable and possible to wear while walking or doing other activities.

-       EMI interference – Any IEM out there should be free of those, but it is good to test against them either way.

Build Quality/Aesthetics

EN700 BASS looks like a modern and stylish IEM, it's outer plates reminding of beautiful works of art, like the well-known Audeze LCD series. The main IEM body is fully made out of smooth metal, leaving a good impression and looking well built.

There is a vent hole in the IEM body that helps with reducing driver flex and gives EN700 BASS a larger soundstage. The nozzles have a metal grill at their end that prevents any kind of debris entering the IEM body. The outer plates look sturdy as well, although they don't seem to offer any more venting or openings other than the venting hole does, being more a design element rather than a functional vent.

The cable is attached to the IEM bodies and it is not interchangeable, but Simgot is working on a version of EN700 that offers interchangeable cables as well. For increased comfort, the portion of the cable that comes in direct contact with the ear is covered in a soft, rubbery plastic and the rest of the cable has a braided design and a dark red-golden color.

There is a small Velcro strip down the cable that helps keep the cable in place during storage, and the 3.5mm jack comes with a small stress relief as well.

The design of the cable looks great and it brings memories of vintage pieces of equipment, especially vintage headphones form before 2000.

All in all, the build quality of EN700 BASS is incredibly good for the price and they are hard to fault. With great aesthetics as well, they look like a combination of stylish and vintage.


While the first time wearing EN700 Bass, I actually tried them with smaller tips than I should have, I found out later that they are actually very comfortable, and there is very little to complain about. They are on the larger size, so people with smaller ears might get different results, but they work well for me. The tips offer a good feeling and they don't get slippery easy, while the IEM bodies don't press against the ear.

Given their shape, EN700 BASS makes very little contact with my ear, most of their weight resting within the silicone tip and the part of the cable that goes around the ear. Happily, this means that the ears are touching very little of EN700 besides those two parts, so chances of discomfort are fairly low.

The cables are nice to the touch feel great when worn, but they are very slightly prone to tangling when stored, but this problem disappears when using the Velcro strap included.

EN700 BASS isolates the listener from the outside noise very well, and it is possible to wear them and take them with you even in the crowded evening streets of Bucharest. People around you won't hear the music you're listening to, and you won't be bothered by other people's conversation and chatter while you have EN700 BASS plugged in.


Simgot EN700 BASS has been tested with Xiaomi Mi Max, FiiO X5ii, Opus #3, HiFiMAN MegaMini, and with our benchmark DAC/AMP, iDSD Black Label. Some of the sound described will inherently be influenced by the source driving EN700 Bass.

Sound Quallity

Simgot EN700 BASS has a surprisingly good sound, especially considering its price point. They are a natural sounding IEM with enhanced bass and a large soundstage. The sound is generally clean and clear, with a tendency to sound smooth in the top registers.

EN 700 BASS has many magical features when it comes to its sound, but one of the best is that they don't really roll-off in any direction and that they offer one of the largest soundstages in a IEM, even if we consider more expensive IEMs.

The music is airy and the tonality is very good, there are no peaks, there is no sibilance and there is no trace of harshness with EN700 BASS, at times being maybe a bit too polite and friendly, presenting most music in a euphoric and enthusiastic way. Given their enhanced bass, EN700 BASS will probably fall into the warm types of presentation, but they are one of the most natural IEMs in the ~100$ price range I've heard.

EN700 BASS is extremely forgiving of bad recording conditions, painting even some of the poorest recorded albums in a friendly light, quietly hiding away all of their flaws. There is no trace of sibilance or other unpleasant sounds even when the album was purposefully painted with a screechy sound in mind, and many fans of older albums will surely appreciate this.

Little disclaimer: 

All the sonic impressions have been taken using iDSD Black Label, FiiO X5ii, Opus #3 and HiFiMAN Megamini. All of the above are impressive sources and they will have an impact over the sound of Simgot EN700 BASS.

Channel balance

This sample of Simgot EN700 BASS presents absolutely no channel imbalance, even after proper testing and measurements, both channels playing in unison at the same volume.


One of the first things that impresses the listener when it comes to EN700 BASS is their strong and deep bass.

EN 700's bass presents no audible roll-off and offers an amazing presence and quantity. The impact is very good and EN700 BASS presents the bass with a healthy initial strength, being able to shake the listener from his place. It also offers a natural to long decay, giving EN700 BASS a signature rather suited for bass-heavy types of music.

It would be safe to name EN700 BASS a basshead's IEM, but compared to other bass-heavy IEMs, EN700 BASS has a clean and deep bass, that doesn't bleed in the midrange. It is nice to notice such a clean and strong bass in their price range, the bass never overshadowing other elements in music.

Bass textures and bass details are fairly good for EN700's price point as well.

Ken Ashcrop – Absolute Territory – The song starts strong, the first few synth sounds being clear and strong, with the first bass notes being powerful and deep. The song has a dark to natural general tonality and the voice sounds sweet and enchants the listener with its magic. The chorus has good detail and it is possible to hear all the cymbal symbols in the background, but they will continue to keep a clear background position, especially when compared to the bass which is played in the front of the listener. The mids usually keep a safe and midway place while the soundstage and airy presentation gives the song a healthy 3D presentation with symbols even coming from the back of the listener at times. It is totally possible to embark on a trip with the singer, traveling through his adventure with his lover as he sings about how he meets the love of his life.

Rings of Saturn – Peeling Arteries – The song starts with extreme impact and force, the cymbals playing along with the guitars and the crispy drum patterns. The voices carry an amazing impact and strength to them while the bass notes are deep and strong, being very easy to start softly headbanging while listening. The song envelops the listener and takes him through the dark post-apocalyptical world painted by Rings of Saturn, a place where aliens have invaded and are slowly disintegrating Earth. For the record, I have been quickly tapping my feet on the floor for most of the song duration, sometimes closing my eyes and living through the cosmic travel painted during the solo of the song. The speed of the drums is very good and EN700 Bass are able to paint quite a realistic image of the song's pace. 

Minesweepa – Dropping Bodies – The song starts with good strength and although the synths carry little bass information, EN700 enhances that bass and gives the build-up a good emotion and impact. When the song truly starts, the listener is dazed in place by the depth and force of the bass. The cymbals continue playing in the background, while the bass is in the front taking names and shocking the living being out of the listener. The song doesn't have a story by itself, but the trip of listening to this dubstep piece is amazing through iDSD BL + EN700 BASS. For the record, there have been a few times where the drum patterns coupled with the large soundstage have actually made me get up from my chair and look around, thinking that something fell in my room.

Leningrad – Healthy Holidays – The song starts softly with a few gentle guitar notes combined with piano notes, while the voice sings in the front of the listener and declares itself as the main element of the song. There is a clear sense of bass and play-like elements in the song while the accordion and other instruments play happily like they usually do in an avant-garde opera. The song, although having a rather grotesque message, is presented friendly and happily with an enthused tone. The trumpets have a good impact and strength to them, sounding pretty clear and alive.


The midrange of EN700 BASS is clear, natural and has a touch of thickness to it, presenting music with a good tactile feeling. The textures are pretty good for the price, while the soundstage is rather incredible considering its price range.

Both male and female voices are presented with a slight tilt towards a sweet tonality. EN700 BASS will present most music in a friendly way, being quite the agile IEM when it comes to hiding things.

The midrange is presented with good textures and has a nice depth to it, brass instruments having a nice tactile feeling to them, guitars presenting tasty and crispy riffs and pianos having a melodic touch on every keystroke.

Being rather musical, EN700 BASS is a good combination with almost type of music that is supposed to sound happy and playful, presenting things in a joyful way. Rhythm guitars, in special, are presented with sweet undertones to them together with usually slightly longer decay of each note.

3OH!3 – Déjà vu – The song starts with a healthy bass pattern along with the synth patterns playing in the background. The voices are natural and relaxed, having a lsightly melodic tint to them. The story of the singer's life as he visits clubs and does the same things over and over is interesting and his half-asleep style of living can be lived through the song. The presentation is airy and has a good soundstage.

Gakusen-P with Gumi – Sacrifice of the Sheep – The song starts with good speed, presenting all sound in a quick pace and rhythm. The bass is played in the same area as the voices, while the cymbals are played in a slightly more distant space, accompanying the whole song and keeping the rhythm whole. Female voices sound sweet and the emotional involvement is very good and alive throughout the song. The story of the song is presented nicely, the story of the two villages who came to a fight because of their beliefs and who decide to offer a poor innocent as a sacrifice. The emotional impact of the sacrifice's lament can be felt through the song and it is possible to feel the moment when the protagonist is visited by an angel who tells him that he will be saved in the end. The final scene, that of the character's final moments can fill one's eyes with tears and bring a cold shiver down one's spine.

REDFOO – New Thang – The song starts with an impressive selection of bass notes alternating with the cymbals that play in the background. The synth selection has a good musicality and texture to them while the chorus plays with a happy and well-paced tone. The song keeps a warm and joyful approach and it is possible to gently tap one's head or fingers while listening to it.


Simgot EN700 BASS features a smooth treble presentation that is friendly and will hide all defects in a song. There is no trace of sibilance or harshness, no matter how the song was recorded, but this means that EN700 BASS can be a bit too friendly and relaxed for aggressive music, being a slightly dark, warm and happy IEM.

Protest The Hero – I Am Dimitri Karamazov And The World Is My Father – The song starts with an interestingly friendly and smooth approach, keeping the bass as the central element with the voices somewhere in between the bass and the cymbal crashes. This song is usually sibilant and harsh, the fact that it is presented smoothly means that all music will come as happy and enthusiastic through EN700 BASS, a musical and fun experience for those who want to have a happy day. The story of the solider who is exiled by his family to fight against his will is presented a bit happy, and while it doesn't keep the whole range of emotional involvement it was originally supposed to have, the vocal tonality towards the end of the song helps with expresing the wail and regret of the solider as he feels that all his life he played a role that was given to him.

Eskimo Callboy – Party at the Horror House – A song about debauchery and a party at a horror house, the way EN700 BASS presents the song is clean and enthusiastic, and although it takes away some of the main original dark element of the song, the final experience is full of life and fun. The cymbals are slightly subdued, but since this song used to sound a tiny bit harsh on certain setups, this change is welcome if you want to have an easy time while listening to it. The voices are again presented clearly and with a good tonality and texture. The bass is defined as the central element of the song, strong, thick and coming through with good impact.

Daniel Kahn and the Painted Bird – A beautiful song about the state of affairs in Germany right before the start of WWII, the song takes the listener on a journey through the daily lives of Jewish families and the segregation they started to feel as the war was becoming more and more a certainty that they feared. The large soundstage of EN700 BASS helps a lot with the presentation of this song since there are many unique notes that need to be played in specific spots for the song to have its intended impact. The cymbal crashes are smooth and played somewhere in the background, but they are clear and well defined. Long wails and accordion notes are played with beauty and elegance while the tone of the song goes dark towards the end as the situation portrayed turns sour.  


Simgot EN700 BASS has a unique way of presenting the soundstage, large in size and well layered, but with a good coherency.

The large size of the driver unit helps a lot with this as instruments are never smeared on one another and there is a nice feeling of air between the instruments. The soundstage performance of EN700 BASS is above its price point and they have a larger sound than most IEMs tend to.


The ADSR / PRaT characteristics are fair for the price point. There is a good sense of Rhythm and Pace and while some musical notes are a bit more extended than they should, they make an interesting and enthusiastic listening experience.

Portable Usage

Simgot EN700 BASS is very portable by default and it works well while on-the-go, especially as it offers a pretty good isolation and has a stylish design.

Given EN700 BASS over-the-ear design, the cables are not microphonic at all, and Simgot included a rubbered plastic over the cables in the area where they come in contact with the ear so the wearing comfort is also very good.

The cables themselves have a nice design and they can clearly be taken outside and shown to other people, and the jack is made out of metal and has a nice stress relief that reads Smigot.

All in all, EN700 BASS is portable and is made to be worn outside.

The fact that the cable is slightly tangle-prone didn't affect portable usage in any way, and it is a fun experience using EN700 BASS outside.

Drive factor

Simgot EN700 BASS is very easy to drive and can achieve close to its full performance when driven from a better smartphone or laptop, the maximum resolution being good for its price point.

Using a better source results in a better sound, but EN700 BASS sounds great from a typical laptop and it is possible to use it happily without much further investment.

There is no hiss coming from EN700 Bass when driven from any of the sources I have, and while there is no option for a balanced cable now, Simgot is working on an EN700 Pro that will sport an interchangeable cable and thus will allow for usage of a balanced cable.


I have tested EN700 BASS in depth against EMI and while they didn't produce any kind of EMI with most sources. It happened twice during the test, for a tab in Chrome to play something at a very quiet volume, and I had mistakenly taken that for some kind of interference.

After running the tests again, it is safe to say that EN700 BASS doesn’t display any kind of EMI interference, even when used literally above the Wifi router.


Simgot EN700 BASS vs Shozy Zero – Shozy Zero sports a different build, EN700 BASS being fully made of metal while Shozy Zero is made out of wood. Each of them take a few inherent sonic properties of the materials they are made of, and Shozy Zero presents the sweet warmth of wood. Both feature a pretty similar presentation, but EN700 BASS has a slightly larger soundstage due to its large size and large driver. EN700 BASS presents no driver flex while Shozy Zero presents a little bit of driver flex inherent from its closed design.

Simgot EN700 BASS vs FiiO F5 – Both are very good IEMs at their price points and I warmly recommend both. FiiO F5 has an even happier signature and tone than EN700 BASS, while EN700 is slightly more natural and presents treble with slightly more energy and sparkle. The bass is great on both and the soundstage is very large on both. FiiO F5 has a fully open design that brings certain differences to the sound, like the airy sound, while EN700 provides more isolation from the outside noise. FiiO F5 is slightly more comfortable in the long run, but both are fairly comfortable IEMs.

Simgot EN700 BASS vs Sennheiser M2 IEBT – While Sennheiser M2 IEBT is a BT IEM, it has a lot of life and an awesome sound, making it a good candidate to be compared to EN700 BASS. M2 IEBT has a much more V shaped signature, with more sparkle in the treble and even more bass, although the bass levels are somewhat comparable. The instrument separation is slightly better on EN700 BASS, but M2 IEBT sports a sweeter midrange, taking many characteristics of their signature from Sennheiser ie800's signature. EN700 BASS doesn't present any driver flex, while M2 IEBT can present a bit of driver flex in some situations.

Smigot EN700 BASS vs Etymotic ER4XR – ER4XR sports a totally different signature, totally different fit type and philosophy when compared to EN700. EN 700 has a shallow insertion with good isolation while ER4XR has a very deep fit with a very high level of isolation. While both present a similar quantity of treble, ER4XR has a far more forward midrange and EN700 has a far more forward bass, making each a flavor of its own, both good flavors nonetheless. The purpose of ER4XR is "a professional tool for performing artists", while EN700 is tuned and made to be a listener's IEM that plays music to be happy and enthusiastic.

Bonus Photos


Taking into account EN700 BASS low price point of about ~100$, it performs very well and is a good value for its price. It doesn't come with a lot of extra accessories, but it comes with a nice brush, a vintage carrying case that will surely appeal to many music enthusiasts out there, and EN700 BASS comes with six pairs of tips, each labeled for their role. The cable is also pretty good and although it is not removable, it provides a high enough quality to work well that way.

The very good build quality also adds to EN700 BASS's value as it is a good indicator that they are built to last and that they are a smart investment if you were looking for a good IEM at this price point.


Reviewing EN700 BASS has been a lot of fun and it has proven to be one of the most natural and balanced IEMs in its price area. There are many contenders to the "Best 100$ IEM", but Simgot is climbing to the top of this mountain, managing to impress their public with just two entries so far.

Given their fairly balanced sound, large soundstage, good instrument separation, musical/happy presentation and very good build quality, it is very easy to recommend EN700 BASS to everyone who is interested in one of the best 100$ IEMs out there.

The cute vintage leathery case is a plus that many will appreciate and Simgot promises to bring even more great IEMs in the future, being very enthused about their work.

Thank you for reading, I hope that this review is of help to you, stay safe, and please remember to have fun while listening to music!
