Meet the Sennheiser Flex 5000
Enjoy TV sound in premium quality without giving up your favorite headphones.
The Flex 5000 is a TV listening amplifier that turns your wired headphones into a wireless TV audio system.
It delivers a listening experience adapted to individual hearing needs and, thanks to long battery life and high wearing comfort, guarantees many hours of enjoyable TV listening.
The Plus For Your TV Sound
Hear everything, enjoy everything. Even the best TV programs can get better with great sound. That's exactly why we developed the Flex 5000.
This innovative audio device lets you adjust volume, listening profile and even speech clarity to your personal preferences. You can simply use your own wired headphones, because the Flex 5000 makes them part of a wireless TV audio system. Move freely while you enjoy your TV sound. You're too experienced to accept poor TV audio as a necessary evil: make your TV sound more vivid. With more clarity, more comfort—and the wired headphones of your choice.
The Plus For Your Listening Experience
Want a better program? Choose a different channel. Want better sound? Choose Sennheiser.
Just plug it in and you can tailor TV sound to your preferences. Choose from three listening profiles that deliver clear speech and vibrant music reproduction. Adjust left/right balance to whatever feels comfortable for you.
The Plus For Your Freedom
The Flex 5000 frees you from cable constraints and lets you move within a radius of up to 30 m. With up to 12 hours of battery life, you're well prepared for long TV evenings.
The Plus For Speech Clarity
The Flex 5000 features a unique speech-clarity function that isolates speech from the surrounding audio at the press of a button. Background noises in the TV sound that could mask speech are dynamically reduced.
The Plus For Comfort And Easy Operation
Focus on your TV program, not the audio device: the Flex 5000 is exceptionally easy to operate and works with all digital and analog TV audio outputs.
The Plus For Style
The Flex 5000 is a slim, elegant transmitter/receiver set that complements your home system in style. The transmitter also serves as a smart base station to charge the receiver's long-lasting built-in battery.

Flexible Headphones
The Flex 5000 is supplied with ultra-light Sennheiser MX 475 earphones. But you can also connect almost any other headphones with a 3.5 mm jack. Use the wearing style you prefer – in-ear, on-ear or over-ear.

Speech-Clarity Function
With a unique speech-clarity feature you can improve vocal clarity at the touch of a button. Background noises in the TV sound that could mask speech are dynamically reduced. TV content becomes easier and more relaxed to understand.

Wireless Freedom
Digital technology provides wireless freedom and crystal-clear sound with a range of up to 30 meters. The built-in battery allows up to 12 hours of uninterrupted TV or music enjoyment. With the supplied ultra-light Sennheiser MX 475 earphones you can fully enjoy this freedom.
