Final thoughts
The CM338 is simply excellent. The build quality of it is good. The glossy black finish is a fingerprint magnet.

The bass is just nice but not too heavy. The lows and mids are great. 

Tested gaming with COD Mobile and PUBG Mobile with minimal lag.

I hope the next Ugreen TWS comes with aptX.
