The connection via Bluetooth is simple - who has the room before, will have no problems. Otherwise the short english manual will provide - although it would have been better in German. The headphones are marked with left and right, so you can find their way here. Both sides of the headphones are connected via a narrow cable that comes along while wearing headphones at the back.
The cable is relatively little after, and then designed the placement of the headphone for small fumbling - at least the first few times. If one uses the headphones often, one has to it certainly used to. The headphone ends are incidentally caught over his ears - it may be so that eyeglass wearers would shortly take off for their Briller. Otherwise, however, can be worn with a pair of glasses these things also. The qualitative impact of the processing is fine. The sound is of such small headphones in order, even though I had better tonal headphones.
CONCLUSION: The manual is then only in English, but it illustrated. The Bluetooth connection to the mobile device (eg smartphone) should therefore not be a problem. The headphones can be surprisingly comfortable and ergonomic wearing the head, even if the placement - at least initially - may be to small fumbling. The sound is okay, satisfying, remember you the price of the headphones. For sports activities, they should be suitable. Charge by the way can persevere in approximately 2.5 hours by USB on the PC, and then you should go for around eight hours.
