ø6mm Dynamic Driver


A product that was hyped around the net - MEMT X5 - has finally reached my hands. I gotta admit, I wasn't expecting such performance from tiny micro-drivers. I was shocked and still am shocked as these have become one of my favorite earphones thanks to their delicate and crisp highs alongside the gentle and nonintrusive mids.

NOTE: MEMT has replaced X5 with X5S, which includes a brand new cable (a braided fabric one, just like X9) that replaces X5's stiff plasticy cable, and also a black color variant was added.

Sound signature: Bass-centric


  • Without exaggerating, one of the best-sounding earphones I've heard in a long time. You can't go wrong with these earphones, no matter which music genres you're listening to.
  • Superb build quality, with magnetic adsorption. I rarely say this, but I have absolutely no complains about the build quality of these earphones.
  • The cable was properly rolled inside the package, which resulted in a super-straight cable out of the box. A real pleasure.


  • Not the loudest earphones, the mids and highs are recessed compared to the lows.
  • Single-flange tips were not included in the package, which were a must for a perfect seal with these earphones. Consider buying simple, soft tips along with these earphones just to be on the safe side.

Comfort & Fit

I always have troubles with double-flange tips, they never seal properly for me, and that resulted in a cold bass-less sound. Once I replaced them with some soft white L-size single-flange tips, I unleashed the full potential of these earphones.

With that being said, including only double-flange tips was an unwise decision, as these tips are not fit for every ears.

Lows / Bass

What?! These tiny drivers have some of the deepest, quickest and most accurate bass responses I've yet to hear! I never imagined that I'll live to hear micro-driver earphones that product super-satisfying, eardrum-shaking sub-bass as these do!

Besides the sub-bass, the mid-bass and upper-bass are very well-defined, punchy, warm and enrich the already superb mids these earphones have.

Mids / Vocals

Some of the best mids I've yet to hear. They are very present but not overemphasized, not harsh and never sibilant. Vocals are far enough to be comfortable for a very long listening session, but are also a bit too recessed for my taste. These will handle literally every music genre you might throw at them, even complex pieces like metal.

Highs / Treble

Very sharp and crisp. High Definition would be very accurate to describe the level of clearness and detail these earphones have to offer. The peaks in the upper-mids and highs are quite subtle in a very bright, yet well-balanced way, never causing discomfort or sibilance.
