Summary: I'm using these to listen to our TV; they are connected to the headphone out.
I bought them to replace my failed Sony MDR-RF4000K, but I'm not too sure if it was worth it. Compared to Sony, I can't really say there is *any* improvement, maybe only when playing GT5 - Sony had a very weird problem...
Pros: Sound fairly decent
Cons: Cut out when input volume is low; cups are too shallow for my ears, manual switch on
Summary: These are enjoyable headphones as the surround really envelopes and clarity shines. Overall sound lacks a little richness, highs are overpowering. Nice punchy bass, not too much. After 1.5 to 2 hours they are fatiguing as most wireless headsets are. They are very light weight and comfortable.
Summary: The RS 170 continues Sennheiser's unchanging dedication to sonic clarity and they're well worth the price for anyone looking to grab wireless sound from a TV, AV receiver, cable box, or game console.
Pros: The Sennheiser RS 170 is a full-size set of headphones with Kleer wireless technology that delivers CD-quality sound.
Cons: The awkward placement of the controls on the right earcup may require a longer learning curve for some users, and the transmitter/charger base lacks digital inputs.
