After having wireless headphones Sennheiser for years the last one I bought was more than mediocre RS170. I have also returned. The Sony headset is simply a killing !!!! +: > There are very very comfortable, it is discreet. > All buttons are easily accessible. No risk of touching the settings when you press the head on the couch unlike Sennheiser. > Optical Connection > Super Design > Pleasant to the touch > Numerous configurations (3D sound, bass booster seat ...) -: Average range (it cuts beyond 10m)
