Connect the base station to your television, and the wireless receiver to your favourite wired headphones to create your own wireless TV listener.  Listen to TV at your own volume through your headphones, whilst other people in the room listen through the TV’s loudspeakers. 

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.  A small set of MX-476 earphones are supplied, but you can use any wired headphone with a 3.5mm jack.

The Flex 5000 empowers your wired headphones to give you a dramatically enhanced TV sound experience. Just plug them in and you can customize your audio according to your requirements, with a choice of three different hearing profiles, which deliver clearest speech and colourful music. And, of course, you can adjust the left and right volume for a pleasant and balanced sound.

Flex 5000 gives you the freedom to move within a range of up to 30 m and have extra-long TV sessions, thanks to rechargeable batteries with up to 12 hours of playing time.

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. The Flex 5000 does not only offer easy and intuitive handling. It also provides full compatibility with digital as well as analogue TV outputs.

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.
