From any room in the house, through walls and ceilings, even out in the yard, the RF 85 can pull in the transmitter's signal up to 300 feet away. Not coming in crystal clear? The RS 85 comes equipped with Center-Lock™ Auto-Tuning. A simple touch of a button, and the headphones automatically adjust to the transmitter.

The transmitter comes with a built-in audio filter designed to eliminate TV interference. Inside the 'phones, another filter removes RF interferences, giving you a crisp, clean signal.

Sennheiser's RS 85 headphones come with two NiMH battery packs to maximize your listening time. Simply charge one battery while you're using the other!

Features

BioNetic Design: Sennheiser headphones adjust to the shape of your head, with their joints, flexible materials and extendable arms. Comfortable cushions provide optimum comfort in those places where sturdy material would rest on your head.

Transmitter: The system comes with an RF transmitter that connects to an audio source via a headphone jack or preamp outputs. The transmitter sends a 925 MHz signal to the headset, using one of three selectable transmission channels. The transmitter has an automatic On/Off function. The transmitter switches on and begins transmitting when it detects an audio signal, and will switch off if it detects no audio signal for 3 minutes. The transmitter also functions as a battery charger for the supplied NiMH rechargeable batteries and a storage stand/charger for the headset when not in use.

Headset: The headset features soft velour ear pads for listening comfort. The right ear cup has a compartment for the user replaceable rechargeable battery, an On/Off switch and controls for tuning and headset volume. The headset also has contacts that allow the battery to be recharged when the headset is placed on the transmitter/storage stand.

Rechargeable Battery Packs: Power for the headset is provided by a small NiMH rechargeable battery pack (called AccuPack) that fits into a compartment on the headset. The system comes supplied with 2 AccuPack battery packs. The battery in the headset is recharged whenever the headset is placed on the transmitter/storage stand, and a small charging compartment at the back of the transmitter keeps the spare battery charged. A fully charged AccuPack has an operating time of approximately 3.5 hours. The batteries are interchangeable, and if needed, a discharged battery can be swapped with the spare battery from the charging compartment. The manual recommends an initial charging of 24 hours before the batteries are first used, after that the normal charging time is 14 hours.

HiDyn Plus Noise Reduction: The headphones feature HiDyn plus noise reduction for wide dynamics and superb sound quality.

CenterLock Auto-tuning: The CenterLock tuner makes sure the RF transmission signals come in crystal-clear at distances of up to 300 feet. With the touch of a button, the clearest signal is automatically tuned in.

Audio Filter: The transmitter comes with a built-in audio filter designed to eliminate TV interference.

SAW Input Filter: The SAW input filter removes RF interferences, giving you a crisp, clean signal.
