Have purchased the Bluetooth headphones for my children. For the price I was indeed on the quality a bit skeptical but was quickly disabused. Headphones for the first time fully charged and easily connected to the phone (Power button and hold long). After the surprise. The headphones hat a rich bass with the high notes not roll over. Of course the sound is dependent on the quality of the abzupielenden file. Battery performance depends on the duration and volume and 8 hrs. To 5 days distributed within the acceptable range. Unfortunately you can not multiple headphones with a source about bluethooth connect (the phone is detected only one device, since it can be used as a headset) If the battery times but empty, a cable is that connected via the jack plug to the phone can be. The Earphones feels light and the shells are stuck, but without pressing on the ear. Due to the good padding that are also extremely Soundproof, I do not allow my children to use the headphones on public roads.
Conclusion: I am thrilled with the headphones. Home enjoy music or movies, while within 5m of the source (not through walls) to be mobile without disturbing cables and other not to annoy, what more could you want.
