Enjoy a customized TV-viewing and listening experience with the Flex 5000 from Sennheiser. Included with this system are an RR Flex Receiver and TR 5000 Transmitter. The transmitter connects to either a digital or analog audio source and then broadcasts that audio signal wirelessly to the receiver from up to 98′ away. Once received, the Flex Receiver then outputs the audio signal to wired headphones, such as the included MX 475 Earphones, or induction loop for use with a hearing aid. In addition to transmitting and receiving audio signals, you can also tailor the volume, sound profile, and speech intelligibility to your specific needs and preferences.
Because the RR Flex Receiver is a small, clip-on device, you’re free to move around untethered by wires or cables. Its built-in rechargeable battery lasts up to 12 hours and can be recharged using the transmitter, which plugs into a wall outlet using the included charger and country adapters.
