Right away: Who really wants to hear quality music in the best HiFi which engages the wired headset. But if it is to be wireless for the known reasons, the new digital wireless headphones as the Beyerdynamic RSX 700 have significant advantages over the still largely analog competitors. By design tend analog wireless headphones namely the strong noise and are therefore recommended maximum for television. When trying out a number of digital wireless headphones in a specialist market but noticed that although none of the noisy models, but for other noise like hum and crackle (Philips SHD 9100) occur. The only headset that was completely free of background noise and sound convinced was the Beyerdynamic. The digital radio transmission to 2.4 GHz enables a signal to noise ratio of 85 dB. This is top class for a wireless system and actually means - no hum, no whistles, no chirping. Other benefits include the acceptable comfort at relatively low weight (270 g), and the operating time with batteries of about 5 hours. Nevertheless, there is not a perfect score, because a number of points are capable of improvement, namely (1) the circular shape that can not adapt perfectly to the ears, (2) the fiddly cable connection for docking station, (3) the plastic-heavy processing , (4) the fiddly volume control via push buttons on the handset, and (5) the something small range - perhaps 15 meters - which makes, for example, when walking around the house with audio breakup noticeable. I also had another problem - when connected to the speaker jack of my plasma TV, the headset turned off more often by the automatic signal loss shutdown. When connecting the base station to the Adio output (RCA jacks) using the supplied adapter cable problem then occurred no longer on. Conclusion: At the moment, for the price of about 140 well without competition, but execution and processing could be better.
