Sennheiser RS-220 Audiophile Wireless Headphones

If today's High Definition A/V components are a high-performance exotic sports car, the RS-220 is the driver. And you're at the Grand Prix!

Audiophiles have long asked when the audio quality of the legendary HD 600 series (HD 600 and HD 650) could be ported to a wireless format. Utilizing powerful developments in Wireless Audio transmission, the RS 220 bridges the gap between wireless and wired Headphones via DSSS. Able to work in crowded RF environments amongst Bluetooth, Kleer and Wi-Fi signals, the RS 220 delivers clear, clean, uncompressed audio without the need for tuning.

The transmitter/charging dock features Digital inputs in Optical (Toslink) and coaxial formats. Analog RCA inputs with input-gain control round out a versatile interconnect panel. Each input is duplicated into an output, allowing you to feed other audio components within your system (also known as daisy-chaining).

The headphones (receiver) feature a line-of-sight range up to 300 feet and are engineered for outstanding performance in your Home Theater or listening room.

You have spent countless hours, days, months, and years choosing your hi-fi system with painstaking attention to detail. The new RS 220 is prepared to take that entertainment to new places.
