I once put together the positive and negative points.
+ Packaging
+ Shipping
+ Processing except for a few points
+ Supplied bag
+ Design until earpads
+ Battery life
+ Bluetooth connection
+ Material
+ Manual
+ - Sound (mediocre sound but he clinks partial and lacks some bass)
-Tragekomfort (The earbuds are not well padded and slippery, long wear very difficult)
chutes from the head with minimal movements to the front
-Blue LED too bright
