Three new wireless headphones from Sennheiser compete in the high-end wireless headphones market in that the wireless transmission is based on uncompressed "Kleer" technology.

The 2.4 GHz digital radio transmission method ensures smooth transmission with a high signal-to-noise ratio of 85 dBA. The Kleer technology even allows the listening pleasure to be shared, as up to four headphones can receive radio signals via one transmitter.

The RS 160, RS 170 and RS 180 headphones also afford an unusually high wireless range. Sennheiser specifies it as a radius of up to 65 feet for the RS 160, 262 feet for the RS 170, and a whopping 328 feet for the range topping (in both senses of the word) RS 180. These maximums presume ideal operating conditions (line-of-sight, with no interference from other radio signals).

After the Kleer system delivers the audio signals without degradation, dynamic transducers with powerful neodymium magnets (with a rated distortion of only 0.5 per cent) reproduce the music. The frequency response is specified as "from 18 to 21,000 Hz," and the maximum sound pressure level is 110 dB.

Sennheiser ensures that the new ‘cans' look the part, with clear lines and sophisticated, reflective surfaces in black, silver and anthracite.

The headphones, with their soft padded ear cups and adjustable headbands, are specifically designed for hours of television or music enjoyment, and remain comfortable to wear throughout a lengthy movie, says the firm.

Both the RS 160 and the RS 170 are closed headphones designs that have a volume built into the headphones. The RS 170 also offers dynamic bass boost and switchable surround sound simulation.

The RS 180 model is an open design that, says Sennheiser, "ensures a particularly natural listening experience which can be set to individual preferences." For home theatre use, it offers dynamic compression (Automatic Level Control) and the balance can also be individually adjusted.

Any of the three connect to the wireless headphones via a transmitter that automatically transmits the audio data to the headphones whenever it's connected to a television set, audio system or DVD player. Switching on the headphones is all that's necessary to receive the signals.

The transmitter of the RS 160 can be powered by the included wall adapter or batteries and has a diameter of 3.75".

The RS 170 and RS 180 transmitters feature a vertical, desktop design that also serves as a charging cradle.
The trio is available now for $299.95, $399.95, and $499.95 for the RS 160, RS 170, and RS 180 (respectively).
