Cons: 1) Mediocre Isolation
MEElectronics does one thing better than almost any other headphone manufacturer, they always pack a ton of value into an affordable price. CW31's not any different.
Meelectronics describes CW31 as "Clarity Series In-Ear Headphones Crafted for audio perfection, the CW31's wooden housing resonates with the music, giving a natural touch to the clean and clear sound, while the small size and light weight allow for easy insertion and long-lasting comfort", these earphones are designed to be a relatively inexpensive choice for users who are accustomed to clearer more analytical sound signatures

Packaging : CW-31 ships in a rectangular plastic box, the earphones and the case are resting inside a tray. The new case provided is slightly thicker than the clamshell case that comes with M series earphones. The case is solid black except for the glaring purple zipper which might be an eyesore to some.
Build Quality : The CW31 housings are made of wood and plastic which are sturdy. Strain reliefs are made of hard rubber and ends with a lower-profile 45-degree plug. The earphones feature two vents, one at the rear of the housings and one, very tiny vent next to the nozzles with the nozzles being oval shaped
Cable: The cable is the typical gray MEElectronics cable. It is strong and low on microphonics
Microphonics: None unless you really really try. Excellent cable.
Comfort: These IEMs are very comfortable to wear,being an oval shaped insertion design that allows these to pretty much disappear in ones ears. Deep insertion levels as well as wearing them over the ear are not possible due to the oval shape.
Isolation: Isolation is average since deep insertion is not possible, but the included Double Flange/Triple flange improves it a bit.
Burn-in: Its been burned to 100+ hours before the evaluation.
Amped / unamped: Not much of a difference, these are drived easily by even low power sources
Signature : The sound signature is mostly neutral in character and frequency response or in short analytical
Lows: It isnt bass heavy as its basically neutral, but it still packs a decent amount of bass enough to be enjoyable for most music
Mids: The midrange is nice and smooth, very slightly forward and linear with superior detail.
Highs: It has pleasant harshness and treble response, is similarly linear and rolls off gradually as you approach the top end.
Soundstage: Sound stage is average but slightly better than M series IEM's
Final Conclusion : Meelectronics CW31 comes at 39.99$ which is great for a balanced IEM's with a good touch of neutrality and a bang-for-buck indeed. I rate CW31 as a great IEM in meelectronics series above all M series IEM's and below Balanced armatures A151 and A161P in SQ. They outclass many contestants in its range and undoubtably one of the best balanced IEM's around 50$. CW31 is for those who want to experience clarity, detailing and neutrality at a affordable price.
