The RF wireless mobility allows you to enjoy music for a wider range whether in another room or outside. You may just quickly adjust the settings for a clearer voice quality. The Sennheiser SET 840-TV is very easy to setup and manage. This device is perfect for the plasma TV. The wireless headset has an auto-tuning – automatic channel search which you can turn on the receiver. Its receiver automatically turns on/off when it’s being put on or removed. They have made the battery of Lithium polymer which gives longer operating time of up to 9 hours. The weight of the receiver is very light.

Design and Build

Its ear pads are flexible, and it gives you comfort when you wear it even for a prolonged time. The receiver has a large volume and balance control rotary knob which allows you to adjust the loudness quickly and set the volume for the right and left ear.

Sound Quality

The Sennheiser SET 840-TV uses Neodymium magnets & Duofol diaphragms. It’s an audiophile-grade sound reproduction that creates an excellent stereo sound.
