This innovative audio product allows you to tailor the volume, the sound profile and even the speech intelligibility to your needs while using any wired headphone – virtually turning it into a wireless listening system. So, you can move freely while enjoying your TV sound.
    You are too experienced to take poor TV sound as a given: Intensify your listening. Add clarity and comfort to your TV sound, using your– or any other – wired headphone of your choice.
  • Your + in sound experience
    Want a better program? Zap. Want better sound? Get a Sennheiser. – The Flex 5000 empowers your wired headphones to give you a dramatically enhanced TV sound experience. Just plug them in and you are able to customize your audio according to your requirements, with a choice of three different hearing profiles, which deliver clearest speech and colorful music. And, of course, you can adjust the left and right volume for a pleasant and balanced sound.
  • Your + in freedom
    Unleashing you from the ties of cables, the Flex 5000 gives you the freedom to move within a range of up to 30 m and have extra-long TV sessions, thanks to batteries with up to 12 hours of playing time. With the included ultralight MX 475 earphones you can really enjoy this freedom to the full.
  • Your + in speech intelligibility
    The Flex 5000 features a unique Speech Intelligibility function that makes speech easier to understand at the push of a button. It dynamically reduces background noise, which is part of the TV audio but may interfere with the spoken word. This makes for a much more relaxed listening experience.
  • Your + in comfort and simplicity
    Focus on the program, not on your device: The Flex 5000 does not only offer easy and intuitive handling. It also provides full compatibility with digital as well as analog TV outputs.
