Sennheiser RI 830 Stethoset receiver

Set 830-TV
Your individual
listening pleasure
The Set 830-TV is an infra-red stereo
TV listening system. The set enables
listening anywhere in the room with­
out the need for cables and without
disturbing others. Directly connectable
to a TV, hi-fi system or radio, the Set
830-TV guarantees outstanding sound
quality, which, for example, thanks to
treble emphasis, can be customised to
the listener’s hearing.
What’s more, the receiver is extremely
lightweight and, with its perfect-fitting
ear cushions, offers maximum comfort
when worn. Ergonomic controls and
visual signals for the individual control
processes mean that operation of the
Set 830-TV couldn’t be easier.
