Mrice's popular E300 have made quite a hype. I picked them up for testing, and wasn't particularly impressed. They have muddy mid-bass, almost no sub-bass and extremely dark and off-tone mids and highs. There are better alternatives in their price point.
Also known as: BALDOOR E300
Pros
Decent sounding bass with a dark signature.
Robust build quality and effective design.
Triangular cable design, very soft and tangle-free.
Cons
The mids and highs are dark, unclear and lack any detail.
Even though they are bass-oriented, the sub-bass is weak and gets distorted easily.

Lows / Bass
The bass is pretty moody and there is very little depth/sub-bass to it. It's all muddy mid-bass basically. The bass shaker test resulted in a lot of nasty distortions.
Mids / Vocals
The vocals are very dark, off-tone and lack any detail, partially because the highs are so bad. Sibilance is very noticeable.
Highs / Treble
The highs are not crisp at all and lack detail. Very dark and harsh. No brilliance but a lot of sibilance.
