High-quality 40mm drivers with neodymium magnets deliver clean, detailed sound with rich bass. And the headset's soft padding lets you listen comfortably for long periods of time. The provided rechargeable battery pack gives you up to 14 hours of operation, and it automatically refreshes its charge when the headset's placed on the storage cradle. You can also power the headset with two "AAA" batteries (not included).

With hearig loss enables me to listen to TV dramas.

Product Research



Transmitter: The system comes with an RF transmitter that connects to an audio source via a mini-jack or left and right RCA audio jacks. The system also comes supplied with a 1/4" headphone adapter. 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 auto-tuning button, 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.

Auto Tuning: The wireless headphone's Auto Tuning feature scans up and down the transmitter's 3-channel RF band to automatically tune in the clearest channel for the best reception of your audio signal.

Noise Reduction Technology: The MDR-RF970RK headphones provides enhanced clarity and sound with minimal transmission noise due to its built-in noise reduction technology.

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 14 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.

Range: Depending on conditions, the headset has a maximum range of 150 feet.
