The RS 180 makes movie and HDTV marathons an amazing experience thanks to the Automatic Level Control that compensates for variances in the volume of program material to enhance speech intelligibility...just set your comfortable volume level and let ALC do the rest. The RS 180 utilizes KLEER's lossless digital wireless audio transmission, offering a range of up to 320 feet of audiophile-grade sound and reception to four optional pairs of Sennheiser KLEER headphones. Never fuss with tuning again thanks to automatic, interference-free pairing between the headphone and transmitter. The entire package includes a headphone (HDR 180) and a multi-purpose transmitter (TX 180) which also functions as an 'easy-charge' cradle and docking station.
