The initial charge was needed 2.5 hours, and I could use it 9.5 hours. Even when the battery should be traveling empty times, can be switched to cable operation.
The sound quality is to my mind very well (clear sound and the mids and highs are also very good over - Bass is to my mind also optimal), no noise and crack. The telephone function works fine.
The Bluetooth range I find enormously and I can move into my apartment (about 84 sqm) free. Also on the balcony I have received. The sound comes in without any noticeable delay. In my old BT headphones delay was clearly noticeable. Coupling with my Android smartphone and iPad have worked without any problems right away.
The wearing comfort is top for me. I'm wearing glasses and headphones can carry without great pressure for several hours. The headphones should still make time felt, I can easily move these few mm and continuing to listen to any problems.
The processing is for my needs also perfectly fine. The seams on the earpieces is partially somewhat variable and the plastic used seems partly a little cheap. Comparison I but with my other headphones, so it's probably the standard material.
