"Finally, you can listen to your top hits and your favourite TV show at the desired volume - without disturbing your surroundings. Whether movies, music or audio plays, with the new CL7400 OPTI TV headphones from Geemarc you will immerse yourself in a completely new sound experience. Thanks to the latest technology, the transmission is absolutely interference-free and the sound quality is crystal clear. Both the sounds of TVs and other audio systems are transmitted to the headphones with the help of wireless sigls. The volume of the headphones is up to max. 125dB adjustable With the help of the headphones, hearing impaired people can finally watch TV relaxed again without disturbing family and neighbours by loud TV. Hearing impaired people are often very difficult to perceive sounds in certain frequency ranges. For this reason, the TV headphones can be controlled by high and low frequency. This allows you to optimally adjust the sound of the headphones to your needs. The setting is very fast, via a button directly on the headphones. The CL7400 OPTI wireless headphones consist of a transmitter, a rechargeable battery and a comfortable headphone. The transmitter is simply connected to the TV using the included cable (either on the RCA or headphone jack or optical connection TOSLINK). The headphones are wireless and the sound is transmitted via radio. Directly on the headphone, the volume can be adjusted to suit your needs with just one push of a button. In addition, the headphones automatically switch off as soon as they no longer receive a sigl. This protects the battery and does not discharge unnecessarily. The special feature of the CL7400 OPTI headphones is that you can also use the headphones independently without the base station. For this purpose, you can simply connect the headphones directly to your MP3 player or other audio devices using the included connection cable. So you can use the headphones optimally on the go. In addition, the headphones are very comfortable to wear thanks to the soft ear cups. This means that nothing stands in the way of a pleasant enjoyment of TV and music.
