Pros: Nice bass, smooth sound, accessories
Cons: Lack of treble
Packaging - MEElectronics doesn't skimp on extras. Nice compact pouch, SML tips, pair of bi AND tri flanges, as well as a shirt clip.
Build - Wooden housing looks like it will last. The cable has a plastic tube layer over it which makes it quite durable and quiet.
Comfort - Petite body will cause no fit issues. Isolation is average at best.
Soundstage - By no means large but definitely above average. Music extends a small distance away from your ears.
Lows - They possess a generous amount of bass but it is never overdone. It will rattle in bass heavy songs! Will satisfy all but bassheads.
Mids - No bleed from the accentuated lows but it does cause sound slightly recessed. Very smooth and clean overall if a bit too thick.
Highs - There simply isn't enough treble. Recessed mids and recessed highs equates to unlively vocals. What is here though is very smooth.
Impactful bass and extremely smooth presentation makes it a good buy at $30 street. I found the lack of treble to make CW31s very boring but that's subjective.
