Summary: Bought this as the extra set for RS 170. -- it works perfectly. For the first time in months we can both enjoy the same programme, but listen to it at our own preferred volume,. Added feature of surround sound is a huge plus.
Summary: WOW what a complicated and Unstable procedure for pairing. I finally was able to connect both headphones, but the second day when I wanted to use both headphones again , one pair had lost the connection.
Summary: Got the RS170 and after just one day my girlfriend asked me to get her a pair as well. They work perfectly for us. These headphones are comfortable and block out almost all external noise when watching the tv. World Cup in surround sound without the distractions of the world outside.
Summary: After buying the original set and transmitter from 'Very' who had it on offer for a lot less than the best price from Amazon. I needed a second pair of headphones for the wife. I could only match the Amazon price for these so purchased from Amazon.
