Sonically top, reach flop

I recently purchased these wireless headphones in a well-known electronics store for less than 200 euros. The sound has a very dominant and clearly could but something clearer and more brilliant (not for example compare Beyerdynamic DT990 or similar .. volume is ok. The surround sound could be just a bit better. But the sound is OK and the bass agree well. The seat of the headphones can be described as comfortable, but it can happen that you get sweaty ears for prolonged use, even by the powerful seat (not too tight) and the choice of materials of Velourohrpolstermuscheln. At the headset itself can be input on / off, adjust the balance, adjust volume, select frequency search button for the sending station. The headphones with noise reduction, so that a clear, nearly noise-free sound. As for the range, so I am not satisfied with the wireless headphones. Inside the building with 1- 2 walls (5-10 meters) in between like the headphones but not go all that is over there then signal dropouts until the receiver finally fails completely. That is why I am also disappointed by these wireless headphones, because the packaging is 100 m line of sight and so it is probably meant. But I will also times in the building to change the floor or go into the garden and that takes more than the listeners! This should be considered when buying. If walls are in between, according to the latest 10-20 meters is concluded with the receipt and that's not my thing. For the price you should already can demand a reasonable range. However, that is not given here. That's why I have the listener even after 1 day again exchanged for another (Sony 865 for 85 euros -are Although the sound is not as good but the range is almost 2-3 times as much and that counts for me).
