Good to know: The Temple of the headphones running unusually over his ears, down the neck and not on the head.
The operation of the keypads is very tedious because not every single button can be felt, but these are contiguous to find in a circle around the big phone button on the right headphone. So it is initially (loud / quiet back and front /) to a gamble, of the four buttons to find the right. But you get used to very quickly to the operation and fault undermine increasingly rare.
The big phone button is used to turn on and off the headset, answer for coupling to a terminal with Bluetooth and incoming calls.
For battery life I can not say much, only one thing: I use the device now for several weeks (irregularly, estimated to get 10 hours of use) and the unit had not previously be recharged again.
For Use:
So far, the headphones came with a Sony Xperia Z3 compact and a Samsung Galaxy S2 for use in: Sports in the gym, cycling and in the apartment. When cycling annoying noise could be perceived, otherwise it performed flawlessly.
Conclusion: This is good price / performance headphones, which are well suited for casual music listeners.
4 of 5 stars
One star deduction due to the interference when cycling!
