KiiBoom Allure IEMS – The Lightest Sound

KiiBoom Allure IEMS – The Lightest Sound

KiiBoom Allure IEMs are a pair of $99 USD IEMs designed by the new company KiiBoom, with a simple but effective design, a single dynamic driver, and a detachable cable. They will be compared to other entry-level IEMs, including Astrotec AM850 Mk2 (169 USD), IKKO OH2 Opal (79 USD), and HIDIZS MM2 Mermaid (79 USD). 



KiiBoom is a new company that I’m reviewing products from, so it is interesting to see what they got in store for us. Starting with the build quality of their IEMs, and with the outstanding support they have been providing for their customers, they are surely providing good service, and have a bright future ahead of themselves if they keep up the good work. As with most new companies, if you can find their products on Amazon it is recommended to purchase from there to have the strongest support available. The company offers one year of warranty for purchases from their website. 

It should be noted that I have absolutely no affiliation with KiiBoom, I am not receiving any incentive for this review or to sweeten things out. I’d like to thank KiiBoom 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 the KiiBoom Allure IEMs IEMs find their next music companion.

Build Quality/Aesthetics/Fit/Comfort

The overall comfort is good, but there is a bit of driver flex. The cable does not conduct microphonics, and it is the bendy-bendy type that’s comfortable to use, with no memory effect. The IEMs isolate rather well from the outside noise, between 20 dB and 25 dB of passive noise isolation. 

The leakage is low enough to not be important in today’s review. The Allure is fairly easy to drive, with a relatively low impedance of 18 OHMs, and a high sensitivity of 112 dB. With Shanling M3 Ultra, I need about 40 / 100 to sit at a comfortably loud volume and to get a good sonic performance out of them. Allure is an IEM or in-ear monitor with a single dynamic driver that is beryllium plated, and which has a detachable 2-Pin cable. The cable is much better than you’d expect from the price point. 

The comfort is helped by the rounded and smooth inner surface of the Allure, which creates good comfort in my ears. They also have a relaxed sound thast I can listen to for hours in a row, so I’d consider comfort a super strong point of the Allure. 


Sound Quality

The sound of the Allure is something you have to get used to at first, as it is not one of the traditional signatures you usually get from IEMs. They are extremely light sounding, with a light bass, somewhat rolled off sub bass, and a clean, light sounding midrange, which creates a wide feeling, and a brighter, well extended treble. 

The bass of the Allure is incredibly light, to the point where at times it feels like they sound wrong. It is not even the sub bass that is missing, as they can extend down to 20 Hz, and somehow have a strong sub bass, but the mid bass is somehow missing entirely, which gives music a really light sound, with missing fundamentals. The upper bass and the lower midrange has a bit of warmth, which creates the feeling of musicality. 

The midrange is generally dominated by the low amount of mid bass, which also makes it somewhat light and vague, but wide and airy at the same time. The mirage has good detail and resolution, and generally is pleasing to listen to, Allure being one of the most relaxed and generally pleasing sounding IEMs out there as far as I’m aware. The soundstage is very wide, and shallow in depth. We also get outstanding instrument separation and good separation between layers. 

The treble inherits this relaxed sound, which is somewhat waxy, and while this may not make sense, after you hear the allure, that’s exactly how you’d most likely describe it. Note transients are extremely soft, liquid, but with the somewhat musical upper bass and lower treble, the sound is warm, but soft, gentle. The treble has a good amount of energy, you can hear cymbal crashes, but they are never hard. The dynamics of the Allure are surprisingly good, but impact is quite low unless you increase the volume quite a lot. 



KiiBoom Allure vs Astrotec AM850 MK2 (99 USD vs 169 USD) – We have a larger shell for AM850 MK2, so the comfort of Allure is better physically. There is no driver flex on AM850MK2, but there is a bit on the Allure. The sound of AM850 MK2 has better impact, more bass , especially mid bass, and more thickness / fundamentals to the music. Allure sounds more vague, but also more relaxed, relaxing and has a lighter presentation. The main resolution / clarity is similar, with Allure sounding wider and AM850 MK2 deeper and having a more rounded presentation. 

KiiBoom Allure vs IKKO Oh2 Opal (99 USD vs 79 USD) – We have a slightly smaller IEM with OH2 Opal, which results in a slightly better physical comfort. OH2 Opal has no driver flex while Allure has a bit of driver flex. The overall sonic signature is quite energetic though, and OH2 Opal is rather forward and punchy, which is polar opposite from the Allure which is clean, but also relaxed, smooth and lean. Both make good purchases, but OH2 Opal is better for those seeking thrill and excitement, while Allure is better for those who want to relax and enjoy the most laid back signature one can get around 100 USD. 

KiiBoom Allure vs HIDIZS MM2 Mermaid (99 USD vs 79 USD) – The overall comfort of the Allure is better, and they seem to isolate better from the outside noise. Allure also has a much more relaxed sound, with a smoother midrange, less bass impact, less bass depth, but similar resolution and detail. MM2 Mermaid is better for those seeking a typical run-of-the mill V-Shaped sighnatue, while Allure is better for those seeking a smooth, lean and relaxing signature. 


Value and Conclusion

While they come with a really odd and new signature, Allure has a good price / performance ratio, and they have outstanding build quality, with a good cable in the package, a huge carrying case, and good support from the company, making them a great deal for an entry-level IEM if you’re generally fatigued by the treble and overall impact of Chifi IEMs, and want something relaxing and clean, soft and gentle, yet detailed and resolute. 

At the end of the day, if you’re looking at entry-level IEMs, and want one with a super soft, light yet detailed sound, with good comfort and a tuning that’s rather different from the vast majority of Chifi you typically get around this price point, KiiBoom Allure should be an excellent deal and a recommended IEM.
