- Acoustically, there is nothing to complain about - it penetrates only a little music outside (colleagues complain not). Shielding particularly well they are doing, however, not (are also no over ear and flat built)
- May microphone with one decent telefonierne - you can hear the other very well - my interlocutors say that I "am a little further away" and its surroundings are noisy, it is already very difficult.
- By design, they contribute significantly less than the Sennheiser - are less brawny and not flash large around
- They are easily as plastic but well made - there was an emphasis on becoming the everything looks like a cast and has also managed
- Folding mechanism is a bit bulky and I hope that this remains the long-term working perfectly
- Touch operation is super
- The battery life I can not say anything but Nocht Bluetooth connectivity has always been stable and in good quality
=> Have long sought a bluetooth kopfhöer and am very happy with the halo2. it costs only half of mm 400x and is technically not much to this, but is much prettier and much less intrusive => BUY recommendation
