Can only recommend these headphones. Wear them during training (weight training) and they fulfill their job great. From around you get with not so much and the music in the gym did not hear. For me this was very important because too often Kuschelrock in Studio running. For the quality of the sound, I can not say much because I've never had any other Bluetooth headset compared to other. But for me it is perfectly adequate. The bass is not too short. If it is me but at times a little song, 's gives still the equalizer in the mobile phone. Ifs to connect to the mobile phone then this law is simple and well described in the manual. I have a Galaxy S3 and it has worked directly for the first time to link up. Now he recognizes the headphones usually directly automatically by itself. The comfort is very pleasant and expresses neither the ear nor else where. To Akkuleuafzeit Kannicht not say much because I use headphones after 2 days (a day about 3h) always boot but since they still have battery left.
Conclusion: I am excited about the headphones and they fulfill their job level.
