The RS 160 is a two-part headphone system, powered by a couple of NiMH batteries and a transmitter that connects to your output device. It's very simple to set up as the whole system is plug and play. This compact and portable transmitter utilizes Kleer's uncompressed digital wireless audio transmission. It offers an effective range of 20m (line of sight), and can serve up to four pairs of headphone.
This is a nice comfotable headphone for the cost, I have heard better my only criricism of the product is the distance you can be from transmitter from fade or cut out of sound, I have had other wireless headsets that have a longer range then these have. But if you listening to TV or Stereo and not roaming to far these are a good buy.
