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.

Your + in style

The Flex 5000 is a sleek and attractive transmitter/receiver set that makes a stylish yet subtle addition to every home entertainment system. The transmitter also serves as a smart docking station for the receiver that charges the durable integrated batteries.
