Positives:
- Sound is very good, though a bit much treble
- Weight is very low, comfortable to wear
- Does not fall at the first movement of the ears
- Endurance absolutely sufficient (about as indicated)
- Coverage is "fantastic" with about 8 feet by 3 walls :)
-. Full even on an android app for functionality including battery level indicator
Negatives:
- Telephony transmits to much noise on the other side; here a noise reduction would be really attached
