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 completely interference-free, and the sound quality is crystal clear. Sounds from TVs as well as 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 enjoy watching TV comfortably without disturbing family and neighbors with loud volumes. Hearing-impaired individuals often struggle to perceive sounds in certain frequency ranges. For this reason, the TV headphones feature treble and bass controls, allowing you to tailor the sound to your specific needs. Adjustments can be made quickly with a button located directly on the headphones. The CL7400 OPTI wireless headphones consist of a transmitter, a rechargeable battery, and comfortable headphones. The transmitter can be easily connected to the TV using the included 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, conserving battery life and preventing unnecessary drainage. A unique feature of the CL7400 OPTI headphones is that you can 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. This makes the headphones ideal for use on the go. Furthermore, the headphones are very comfortable to wear thanks to their soft ear cushions.
