Let's get straight to the positive aspects of the listener. I find the headphones with regard to design and build very successful. Simple, yet chic. The materials are high quality and the padding is very comfortable, so that you can wear the headset for a long time well. Also, the weight is the comfort more than adequate. You have to store the headphones helps the possibility to retract the speakers.
The condition is really simple and intuitive. It takes place on the headphones on the right side. Here can be a small shift knob adjust the volume, right next to it are the way the connections for battery charging and a plug for the supplied headphones cord. With pressure on the right Ohrlautstprecher allows the headset on and off, pause playback and accept or end calls.
The batteries are charged quickly, the USB cable is for charging in. The battery life varies depending on the volume and mode of use, but more than adequate for everyday use.
For sound quality can say the following: The difference between Bluetooth and corded operation can be heard clearly. I hear mainly classical and here falls on the Bluetooth operation, that the heights are not as clear as in wired operation. The width of the frequency spectrum is different audible. Nevertheless, the playback quality is better than I had feared and just when using the road satisfactorily. Well, that you can change if need be on the corded operation.
The voice quality when making calls is very good, the microphone is working properly.
Conclusion: Great design, high comfort, good battery life and wide range of accessories. The sound quality is better than wired via Bluetooth, the phone function works convincingly.
