Have tested 5 Wireless Headphones equivalent and higher price ranges. For my taste hearing the best sound and the best fit of the headphones. Use simple, nothing complicated. Batteries will last very long. Come with the reach of the whole house (half-timbered) still mind. 100 m in the garden. Although you do not need, but there are other devices, but have tried it. A star deduction because it once but comes from time to time in motion for a short noise. The noise depends on the position of the head. If you move it a few inches in any direction, the noise is gone. Bin no electronics, but I think this is related to the radio transmission together and it will be represented in all the headphones of this type so or something similar. Despite strong buy recommendation. One last tip: Anyone looking for a headset, always testing me several models of the same music source. The sound is very different but each and will be taken from each differently. The same holds true also for speakers and boxes.
