Sony Wireless Stereo Headphones MDR-RF925R

These are proper wireless headphones and use radio frequency so you dont need line of sight for them to work like infrared headphones. Sound quality is great and the headphones have a built in rechargeable battery. They are also charged wirelessly when placed in the cradle as there are no connections between cradle and phones, just let them sit on the docking station. If you forget to charge them, you can also use 2 x AAA batteries. The headphones are in excellent condition. The foam earcups are extremely comfortable and cover your entire ear. Please contact me for more detailed and/or close up images.

Features:

Transmitter: The system comes with an RF transmitter that connects to an audio source via a minijack or left and right RCA audio jacks. The transmitter sends a 900 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 10 minutes. The transmitter also functions as a storage stand/charger for the headset when not in use.

Headset: The ear cups fit comfortably over your ears with a closed circumaural design that follows the ear's natural shape. The double headband's self-adjusting mechanism conforms to the curve of your head for a comfortable fit. The right ear cup has the volume dial and tuning switch, while the left ear cup houses the supplied rechargeable batteries. The headset has contacts that allow the installed battery pack to be recharged when the headset is placed on the transmitter.

Auto Power On/Off: The headset has a self-adjusting double headband with a built-in auto power on/off sensor. The headset automatically turns on when pressure is detected on the headband and turns off when no pressure is present.

Induction Charging: The transmitter charges the wireless headset through induction charging which requires no direct pin contact making connection simple.

NiMH Rechargeable Batteries: Power for the headset is provided by a rechargeable NiMH battery pack, giving you approximately 18 hours of use when fully charged. The supplied battery pack will need to be charged for 16 hours before initial use.

        Note: The headset can use the supplied rechargeable battery pack, or commercially available "AAA" alkaline batteries. The headset is not compatible with any other model of rechargeable batteries.
