I, personally, have owned the ADV M4 a year ago. Though most consumers will find the sound signature of the M4 as boring or lacking in terms of bass or whatever they are accustomed to listening to, audiophiles and musicians alike enjoy how balanced the tuning of the M4 is, considering its price to performance ratio. The M4 is known to deliver amazingly detailed and transparent sound for the itsy bitsy price tag of 40$. The product we’ll be reading about today is one of the most prominent in the audiophile community, the ADV M4. This review is my non-biased comprehension and appreciation of the said earbud.

I do not receive any cash incentives, rewards, or anything from them. I am not affiliated with Advanced Sound in any manner. There is no version 2 of the ADV M4 (yet). Advanced confirmed that it was only the packaging they have changed.

Ī few of you may have noticed that the ADV M4 that I have received came in a different packaging. You can buy them at their facebook page at f b.com/auremfidelitatem or at the Advanced Sound Group official website at. Huge thanks to Aurem Fidelitatem for the iem that we’ll be reading about today, the Advanced M4.
