Bluetooth connection: 4/5, because coverage limits and occasionally small dropouts
Software: 3/5, when the battery is running low beeps that thing terrible, besides you can not inspect the battery level as with other headsets on the iPhone
Noise-Cancelling: 2/5, it filters out almost no noise, sound quality deteriorates drastically
Price: 4/5, appropriate
Audio without NC: 4/5, a little too quiet, a bit too little bass, but really great!
Audio with NC: 3/5, not adequate for the price!
Head Office: 5/5
Style: 4/5, just a bit geeky
Features: 5/5, all the buttons are very useful !! Volume and Sound Control mainly buttons!
SRS: In my opinion, bullshit, I hear no improvements
TalkThrough: A nice-to-have, but not necessary
All in all, 4/5
However, as I also wanted good NC headphones, I ordered in addition today the Bose QC 15, I tested it and there the noise canceling MUCH better!
