Overview: The HDR 170 is an additional (or replacement)
headset for the Sennheiser RS 170 wireless headphone system (item number
143RS170, sold separately). The closed back, over-ear design helps keep external noise out.
Kleer Wireless Transmission Technology: The RS 170 headphone
system features the digital wireless audio transmission technology from Kleer.
Kleer technology transmits uncompressed audio up to 260 feet over a 2.4 GHz digital
link (2.4-2.8GHz), enabling you to enjoy your music without the hassle of cables.
Kleer's uncompressed digital wireless transmission delivers CD-quality sound.
Note: Kleer technology will not interfere
with wireless networks or other 2.4 GHz devices.
Batteries: Power for the headset is provided by two rechargeable
Ni-MH "AAA" batteries (included) that fit into compartments in the headset.
The batteries are recharged using the charger included with the RS 170 system. Fully
charged batteries have an operating time of approximately 24 hours and require
approximately 16 hours to recharge.

Dynamic Bass Boost to deliver deep bass response. It also features selectable
Surround Sound simulation for a private movie theater experience.
