More details on the Sennheiser HDR 175
Overview: The HDR 175 is an additional (or replacement) headset for the Sennheiser RS 175 wireless headphone system. The HDR 175 headphones do not include the necessary transmitter (TR 175), and cannot operate without it.
Headphone Design: The HDR 175 wireless headphones feature a circum-aural (around-the-ear), closed design to significantly reduce background noise. The soft-padded ear cups and headband provide hours of listening comfort. The headphones have controls on the right ear cup: power on/off, volume up, volume down, surround (to activate Virtual Surround Sound), and bass (to activate the Dynamic Bass Boost feature). With the batteries installed, the HDR 175 headphones weigh approximately 10.9 ounces.
Rechargeable Batteries: The headphones are powered by the two included "AAA" rechargeable NiMH batteries (1.2V, 820mAh). The batteries fully charge in approximately 8.5 hours, when placed on the top of the TR 175 transmitter (included with the RS 175 system). Battery life is approximately 18 hours of use. Standard, non-rechargeable "AAA" batteries may be used in the headphones, but the headphones must not be placed on the charging cradle.
Auto Power Off: If there is no signal from the transmitter for more than 5 minutes, the headphones automatically switch to standby mode.
