PLEXTONE X42M
Dynamic Driver

This one has been waiting for a review for a long time. Surprisingly enough, it sounds quite good, especially when compared to some highly hyped earphones. Their main issue is that they are about impossible to position properly in your ear, they just won't go all the way in, and so the bass will sound weaker than it actually is.

Comfort & Fit

These earphones are about impossible to wear so that they are actually in front of the ear canals, and if you push them manually, you will notice a great boost in bass quality and quantity. They also put some pressure on the ears after being used for a while.

Lows / Bass

The bass is a bit cold, and the reason for that is the uncomfortable design. It's still punchy and more than enough for vocal-oriented music, where warmth is needed but kick-drums are not the main thing, but still a shame. Bass shaker test resulted in some minor distortion.

Mids / Vocals

The mids are slightly overemphasized, something that can be improved by sealing the vents on the back, but either way they are clear and upfront. The mids are dominant and perform very well, especially on slightly powered sources.

Highs / Treble

The highs can be categorized as bright, and can be even made brighter and clearer by sealing the vents on the back. These highs are actually very impressive compared to notoriously dark and muffled earphones like the VE Monk Plus and K's K300, and even brighter than the classic VE Monk.
