Whether it's movies, music, or audiobooks, with the new CL7400 OPTI TV headphones from Geemarc, you will immerse yourself in a completely new sound experience. Thanks to state-of-the-art technology, the transmission is absolutely interference-free and the sound quality is crystal clear. Sounds from TV sets as well as from other audio systems are transmitted to the headphones via radio signals. The headphone volume can be adjusted up to a maximum of 125 dB. With these headphones, hearing-impaired individuals can finally watch TV comfortably again without disturbing family and neighbors with loud volumes. Those with hearing impairments often struggle to perceive sounds in certain frequency ranges. For this reason, the TV headphones feature treble and bass controls, allowing you to optimally adjust the sound to your needs. The adjustment is very quick and can be done via a button directly on the headphones. The CL7400 OPTI wireless headphones consist of a transmitter, a rechargeable battery, and comfortable headphones. The transmitter is easily connected to the TV using the supplied cables (either to the RCA or headphone jack, or the optical TOSLINK connection). The headphones are wireless, and the sound is transmitted via radio. You can adjust the volume directly on the headphones with just one button press. Additionally, the headphones automatically turn off when they no longer receive a signal, preserving battery life and preventing unnecessary drainage. A special feature of the CL7400 OPTI headphones is that you can also use them independently without the base station. You can simply connect the headphones directly to your MP3 player or other audio devices using the included connection cable, making them perfect for on-the-go use. Furthermore, the headphones are very comfortable to wear thanks to the soft ear cushions.
