Wireless Headphones: The HDR 175's wireless headphones feature a circumaural headphones (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 Sennheiser RS 175 headphones weigh approximately 10.9 ounces.
TR 175 Transmitter: The transmitter connects to your television's or audio system's audio output via the included 3.5mm cable or optical digital cable (accepts 2ch PCM audio only). You can switch between the two inputs with a provided toggle switch. The audio is transmitted on the 2.4 GHz band (2.40 to 2.48 GHz) with 8-FSK Digital modulation. The transmitter can send signals to up to 2 pairs of headphones at the same time. The extended transmission range is approximately 328 feet (100 meters) without obstructions. (Typical performance with obstructions will be somewhat less.) The transmitter is powered by a 9-volt DC power supply/AC adapter. Adapter plugs for the US, Europe, UK, and Australia are provided, allowing for use in other countries. The transmitter doubles as a convenient charging cradle for the headphones. Transmitter dimensions: 4.96"W x 9.264"H x 3.96"D.
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 transmitter. 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. If the headphones are outside the transmission range or switched to off for more than 5 minutes, the transmitter automatically switches to standby mode.
Dynamic Bass Boost: The RS 175's Dynamic Bass Boost feature raises the intensity of the bass when activated. You can turn the Bass Boost on or off by pressing the Bass button on the transmitter, or on the headphones.
Virtual Surround Sound: The headphone system offers two virtual surround sound modes (Hi/Lo) that simulate the presence of external speakers. Special signal processing produces a spatial sound quality, with differences in intensity between the Hi and Lo modes. You can engage Virtual Surround Sound from the transmitter or the headphones.
