In the RS 180, Sennheiser delivers an excellent sound reproduction. Using an open, circumaural design, the headphones can breathe from both sides of the ear cups, offering you an excellent sound image. This wireless headphone sytem utilises Kleer's uncompressed digital wireless audio transmission and can serve up to four pairs of headphones. In addition, it gives you the freedom to travel up to 100m (line of sight) from your sound source. The RS 180 is also equipped with balance and automatic level controls. The former provides for right/left volume adjustment while the latter for improved speech intelligibility as well as to ensure that the headphones always reproduce at optimum audio levels. Like the RS 170, the transmitter for the RS 180 is multi-functional - doubling as an 'easy-charge' cradle and docking station. All in all, the RS 180 offers a superb sound and an effective wireless range, making it your ideal listening choice!
