Connectivity:
Thanks to NFC and Bluetooth can be the headset within seconds coupled with a smartphone and a manual pairing (that is possibly connected with a passphrase) is omitted. Simply smart phone to the left ear keep ready.
The range of the Bluetooth connection is also remarkable. Since there are many Bluetooth devices that already refuse to serve as soon as a person between the receiver and the transmitter is, I was surprised really positively to this device.
I have tested the range both with my smartphone (HTC One M8) as well as with my laptop (Lenovo U530 Touch) and it is no problem at all to leave the bedroom the laptop or mobile phone, and tigers with the headset through the apartment , Even in the farthest corner (separated by at least 2 walls) I could almost without interruption still hear music with the door closed. Only every 5-6 minutes playing for about half a second was interrupted.
Those who want to can the headphones also classically use a 3.5mm jack cable. This is advantageous, for example, the headset battery is low or you can have ready Bluetooth enabled device for playback.
The only flaw that shows these headphones in this area is that the new standard Bluetooth 4.0 low energy is not supported. This is possibly but at the limit of the data rate, which would be reduced in this feature of 2.1 Mbit / s to 1 Mbit / s.

Battery life:
The internal battery can be loaded easily via the included Micro-USB cable. By the decision to use here the widely spreading standard, the headset can also charge with most phone chargers.
If your battery drained completely, the charging time is approximately 40 minutes, which I find very surprising person. With a fully charged battery you can hear about 15 h then music at moderate volume (warning threshold of the volume on the smartphone).
The only drawback in this case: The battery is firmly installed, and thus in the long run not (or difficult) to be exchanged.

Sound quality:
The sound of the headphones has convinced me fully. All frequency ranges are covered in my opinion, satisfactory and the sound is authentic and genuine.
However, there are also in this area a little deduction, because the shield with the outside world rather scarce and the neighbor in the subway know exactly what you hear, if you turn up the volume a little higher. In addition, the sound quality of the microphone when wind is less than optimal and sometimes noisy (for example when making calls on a bicycle)

Operation:
The operation of the device is super simple and all everyday functions (contrary to Play / Pause, call accept, prev. / Next track, etc.) are very intuitive.
What I liked very well to the control of the mobile phone through the headset, the ability should be performed by pressing the Play / Pause button to redial. Since I belong to the people, which after laying can think of a point which has just been forgotten in conversation, the last number can thus easily re-call (even if you previously called from this number and did not choose the number itself) , Also nice is the feature to mute the microphone by pressing the Volume button.

Processing:
The processing of headphones falling overall very good. Although the headset is mostly made of plastic, this feels very valuable. All hinges and joints are easy but not too easy to move (just as it should be). Likewise is the situation with the attached padded earcups and the bracket, there are no loose seams or other quality defects.
Only the great Power / Play button drops something out of the ordinary, because this has a little too much play in the right ear cup, so that it can be moved slightly. This is a total of not so bad, but this lack ensures that the headphones are not really to use for jogging, as the key rattling through the ups and downs audible.

Comfort:
Through the well-designed upholstery concept and the choice of the material used, the headphones is nice and light on his head and pushes itself not after prolonged wear. By pull earpieces can be the headband also vary in length and is therefore suitable for all head sizes.

Conclusion:
Overall, these are a very solid headset, whose strength lies in its functionality and connectivity.
I recommend this headset has any of enough of the eternal clutter between cell phone and headphones and values good functionality and good sound. Only the sports enthusiasts who are looking for a headset to work, I can not wholeheartedly recommend this product.
