Have now for 1 week, the RS 170 (station) with headphones HDR170 in use. Before that, I had an older Philips used with cables and extension ... can probably everyone think why I wanted them gone. For an analog wireless headphones I could not overwhelm you because the more affordable were too vulnerable. Here are my experiences and information on the part of: Commissioning is not a problem with an illustrated step-by-step quick start guide. Cables are (3.5mm, 6.35mm, RCA) for popular audio outputs. A German, well-structured and illustrated instructions included on CD-Rom. He is pre-loaded with batteries ready for immediate use and interfere (or disturbed) by neighboring DECT phones or WLAN - router. The headset makes a stable and high-quality impression, also the station. The comfort is very good, it weighs about 240g with batteries, but will not even after 2h thanks Soft ear and headband cushions uncomfortable. The cushions are made of a kind Leatherette (very thin) and can make some noise during head movements. But shaved hair and back (slightly longer with me) that's no problem. The term is really OK. After fully charged at the station I could hear well 20h before the LED (to re. Shell) is flashing quickly. Then after about 10 minutes. the sound off. A warning would be good, because the LED can be seen not so if you have it on. The range is absolutely top. If you look too far from the station (with me 25-30m) it is realized only by minor misfires or the signal is completely gone. But no distortion or noise! The SURROUND function is not just a name on the button. When activated really a surround sound effect is created. Criticize I have two things. 1. the key arrangement on the handset. The power button is located exactly between the Volume + | volume keys. So it is easy that you turn off the headset by mistake. The button is designed by Sennheiser as a mute button ... well. 2. is the noise occurring in very quiet tones so 0,5-1s before the onset of the sound. As a fade in / fade out until it is silenced. I then, contrary to the requirement of Sennheiser provided the input attenuation to 0 and adjusted the headphones -Volume at the home theater system. Then it was almost imperceptible => but without ambient noise and soft sounds still audible! Maybe for some users important: The ear cups can be turned only about +/- 10 degrees around the central axis and tilt only about 25 degrees. So turn as DJ equipment is not in it. By KLEER used - technology can also further (up to 4) Kleer compatible Headphones are connected to the station. I can not test, but in the description. Despite the small shortcomings I do not want to miss the part. For my needs, it has everything I need.
Supplementing 12/2014:'ve set high evaluation on 4 * (+). Use the headset for about 4 years. Still works properly, shows no 'wear' for example on the ear cups and even the batteries still hold well. An operation I have accustomed myself, so that I can finally draw a positive conclusion as soon after purchasing the headphones.
