Positive
- Easy coupling with Smartphone (Samsung Ativ S), even after restart
- Good sound
- Function keys very minimalist and thereby clearly (there is a play / pause / call answer button and a slider control for volume up / down and forward / back)
- Comfortable to wear with a fixed seat (wear even after 8 hours at 62 hat size not frequent)
- Chic but simple design, not too chunky
- Selectively operable with cable (virtually with empty battery or not Bluetooth enabled devices and unfortunately Win7, see below)
- Stable and clean processing
- Long battery life, charging a week at a time, at least 10 h operation.
- Works for me even through three thick house walls, the distance I but not yet more than 5m tested
- Slight attenuation of ambient noise, but definitely not a foreclosure.
Negative
- Bass could VLT. a trail more his (Equalizier helps some)
- Of a strengthening of environmental noise, I did not notice anything (was from another recent noted) but the wind whistles happy times in the issues raised by him joint cracks. Very disturbing in autumn.
- Incompatible with Win7 64bit afaik
Other;
Was a bit surprised when I found that the sound is not regulated by the smartphone. So you can put on your phone on Max and the headphones can then still be at the minimum setting and vice versa. Bothers me not, but why the volume control will not work even with cable operating understand another. Not that it would ever have bothered me, just amazes me.
EDIT: Have now the headset for 2 months almost every day in use. When switching between tablet and smartphone you have to start the new headphones.
Phone calls are very pleasant and the voice recognition works great with the headset.
If positive, I would add that the ambient noise is quite muffled. Another reviewer had learned that they would be strengthened, but in my opinion is the VLT. rather the fact that the noise attenuation through the first somewhat unfamiliar sound (which is now but pure conjecture).
