TDK WR700 Wireless Over-the-Ear Headphone

Features
- Non-compressed Stereo Sound – Preserves original 16-bit 44 kHz-digital audio CD signal quality.  Kleer does not compress the audio prior to transmission resulting in uncompromised quality.
- Dynamic Channel Selection Minimizes Audio “Drops” – Audio streams in the robust 2.4 GHz ISM band.  Dynamic channel selection allows the transmitter to monitor interference and switch to another channel if necessary.
- 10 Meter/33 Feet Transmitter-to-Headphones Range
- Ultra-low Power Consumption – 2 AAA Batteries provide 30 to 40 hours of listening time.
- Transmitter a little larger than a 9v battery and plugs directly into the headphones socket.
- No cradle, dock, cables or power socket required; just the small transmitter and headphones.
