Sennheiser Flex 5000 In-Ear TV Wireless Headphones

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.

Unfortunately, it is probably due to the trend of the times that nowadays you get devices delivered that are only ready for use after an annoying puzzle game - unnecessary individual parts and adapters have to be sorted and, if necessary, sorted out. Otherwise, the sound quality of the Sennheiser headphones is literally excellent and whether you get on with the "in the ear" system is up to you - I personally found the wearing comfort of my previous headphones "on the ear" more pleasant.
