Smabat M2S PRO – Earbuds Modularity Go!

Smabat M2S PRO – Earbuds Modularity Go!



Smabat M2S PRO are a pair of earbuds, designed by Smabat, and priced at 64 USD at the moment of writing this full written review. The review will focus on their usage, features, as well as design, as their main selling point is that you can easily replace the driver with other variants available from the same company. 







Smabat actually tagged me in a group mail with many other reviewers, asking us if we’d like to review the new M2S PRO. Most refused, so I assumed the role of bringing those IEMs to you, and sharing the news about them, since they’re worth your attention. The company speaks english fairly well, and like always, I do recommend using Amazon and third party shops rather than going directly for their aliexpress page, as aliexpress packages have the slowest overall shipping time, and the least warranty compared to Amazon and local stores. 


That being said, it should be noted that I have absolutely no affiliation with Smabat. I’d like to thank Smabat for providing the sample for this review. Every opinion expressed is mine and I stand by it. The purpose of this review is to help those interested in Smabat M2s PRO find their next music companion.

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






The package of M2S PRO is fairly simple, with a small cardboard box, black in level, calling the earbuds professional level. Inside the official package, we can find the earbuds, two sets of foamies, the cable, and a carrying pouch, brown in color. The pouch in particular is nice, really really neat for the price.  






Build Quality/Aesthetics/Fit/Comfort


M2s PRO uses a really beautiful cable, and has a detachable cable, based on the MMCX connector. I fail to see how they can provide this kind of quality for portable earbuds, where companies can still sell 300 USD IEMs with worse MMCX connectors, and worse cables, but this just means that Smabat is doing a great job compared to most competition. 



The cable is not microphonic, and I can say that the build quality is top notch. The driver is replaceable, you just need to pull it out, and you can disconnect it from the connector, and replace it. Easy job. The driver inside is a 15.4mm dynamic driver, they have an impedance of 40 OHMs, and they have a sensitivity of 110 dB, basically being driveable from anything. 



Since the plug is single ended, I would recommend using a source that sounds great from SE, like FiiO BTR5 2021, Hiby FD1, Soundmagic A30, iBasso DX240, or Hidizs H2. Anything can drive the M2S PRO, and you should have no trouble using them regardless of the source you’re pairing with them. 


There are two sets of tips in the package, one that’s donuts and one that’s full foam eartips, the earbuds are simply too large to stay properly in my ears, so most of my notes are taken while holding them steady in my ears with my hands. I generally have poor comfort with earbuds, and this is no secret, so please take that into account, but for me they are large, even for earbuds. Using the foam tips helps with the comfort a bit, but they are still big and my fit is very loose, but they sit in my ears without me holding them with my hands. 




Sound Quality


Since I won’t be focusing too much on comparisons, as I haven’t reviewed any earbuds for a while now, I am going to say that I left the M2S PRO to burn in for a while, so regardless whether you believe in burn in or not, I have given them some time to settle in, and for me to settle in with their sound. I have used Astell & Kern SP2000T while taking the sonic impressions, as I’m currently working on a full review on it. All things considered, I am surprised to have to pump the volume as high as 100 / 150 on SP2000T to be able to properly drive the M2s PRO to my natural listening levels. 



The general signature is clean, clear and very detailed, with a warm tint, and a wide soundstage. 


M2S PRO tends to have a really open sound, like most earbuds I reviewed, and since they make poor contact with the ear, the bass tends to be rolled off, from 50Hz downward. This being said, they have a fair amount of substance, and a natural speed to the low end presentation, with a clean and fun tonality. There’s some slight coloration of the midrange from the bass, as the mids are slightly thick, but they are not veiled nor muddy, and the bass is fairly punchy. I can hear bass notes as low as 45 Hz, which is surprising for earbuds. 



The midrange of M2s PRO is sweet, wide and detailed. They have a really natural presentation, with a good amount of thickness, and a good overall width to their sound. The soundstage does have a fair amount of depth as well, with good detailing and resolution. They do sound a bit boomy, especially because the bass rolls off around 45Hz, as per the earbuds design, but the good thickness in the music helps keep things natural. M2S PRO sounds best with either pop, electronic, EDM, or commercial music. 



The treble is slightly bright, airy and well extended. They most certainly don’t lack any detail or extension in the highs, being quite capable of rendering finer details in music. They can be a bit hot and fatiguing, especially for metal and rock, but work well for EDM, Dubstep, Pop and most commercial music. 




Value and Conclusion


Since we’re talking about a pair of earbuds priced at 64 USD, the value is not bad at all, although getting proper fit will be a hit and miss, and you should only purchase them if you know your ears generally work well with earbuds. If that’s confirmed, then the value of M2s PRO is fairly good, and especially that carrying pouch is sweet, the modularity is sweet, and if you’re not happy with them as earbuds, you could scavenge them for the high quality cable and the carrying pouch for more than half of their price. 





Subsequent driver variants and upgrades should be available soon, with multiple impedance versions, and with different tunings, all of them for fair prices as well. 



At the end of the day, this has been an interesting experience, and if you’re into high quality earbuds, modular earbuds, a sweet midrange, and a clean, yet natural bass, Smabat M2s Pro should be an interesting choice.

Full Playlist used for this review


We listened to more songs than those named in this playlist, but those are excellent for identifying a sonic signature.  PRaT, Texturization, Detail, Resolution, Dynamics, Impact, and overall tonality are all revealed by those songs. We recommend trying most of the songs from this playlist, especially if you’re searching for new music!


If you have a dime to spare (donate), it would make my day much brighter, as it would help me improve things around the website and increase the frequency of my posts.
