Sennheiser RS 160 Digital Wireless Headphones

Crystal clear, static free headphones, plug in - turn on - perfect
If static and interference concerns you, pay a few extra dollars and get yourself a good set of digital headphones like the RS 160. All wireless links are affected by low signal strength and interference, the effect on audio quality is a major difference between analog and digital modulation. As the signal quality deteriorates in an analog system the listener hears increasing amounts of static. Very annoying. In a digital system, the audio is reconstructed from a bitstream (ones and zeros) received from the transmitter. Sophisticated error correction routines are used to "fix" errors in the bitstream resulting from interference or low signal strength. The result is perfectly clear audio until the bit errors overwhelm the signal processing in the receiver, then the audio simply drops out and you know you've strayed a little too far from the transmitter.

The RS 160 uses integrated circuits by a company called Kleer to transmit CD quality audio, and that's exactly what...

paradigm shift

I bought these not expecting much and was utterly blown away by the sound quality. The KLEER technology they use results in audiphile grade sound without any of the noise or interference I have had with previous wireless units. I have used them constantly for television and critical listening to music (I'm a musician) for over a month and the batteries in the phones are still holding up. The batteries in the small transmitter gave way after a week but it was easy to set up the supplied wall wart power. They are especially great for late night TV and listening to music in my condo without disturbing the neighbors. Reception is great even upstairs. The phones design is very comfortable and they are well made. The only disappointment was the lag in transmission made them unusable for playing my guitar. For everything else you don't really notice it. Highly recommended and worth the price!

As advertised, with limitations.
This is a good product and, with comment, I would recommend it to friends.

1) Sound: In spite of having old ears (70) I listen with critical intensity and am still aware of limitions in many CDs, LPs and speakers. I consider this headset "very good" -- with clear highs and midrange. I would prefer 10% more bass but could easily provide it with my intermediate amp.

Separation is excellent -- true stereo, no matter where you sit. Of course, this is a benefit of using a headset rather than discrete speakers.

Presence is good -- one feels that the singer or lead instrument is up-front, clear and emphasized.

Although I am not aware that anything specific is missing, the Depth of the orchestra seems limited -- no instrument is farther back. But this is also true in most bookshelf and medium floor speakers. It's not that something is missing in the headset; it's that something "extra" exists in large, high quality speakers (or multiple...
