How to Connect Sennheiser Bluetooth Headphones to TV?

by Avantree Support 15 Apr 2024

Want to connect your SENNHEISER Bluetooth Wireless Headphones to your TV and listen to TV through them? 

No problem! There are TWO ways to do it.

If your TV has built-in Bluetooth capability (please check your TV's user manual), here's what you do:

1. Get your SENNHEISER Headphone into pairing mode (Please scroll to the bottom of the page or see your SENNHEISER user manual.)

2. Go into your TV's Bluetooth menu, search & select your SENNHEISER Headphone to connect.

3. You may adjust the volume via your TV's remote control.


If your TV does NOT have built-in Bluetooth, or if you'd like to connect MORE THAN ONE PAIR of headphones to your TV simultaneously, you'll have to connect using a Bluetooth transmitter for TV, something like these:

Avantree Audikast Plus (Learn More)


Avantree Oasis Plus (Learn More)
Oasis Plus


Avantree TC419 (Learn More)

With these, you'll be able to:

- Get extended Bluetooth Range.

- Connect up to TWO PAIRS of headphones to your TV (adapter) simultaneously.

- In the case of Oasis Plus, it can be used simultaneously with a SoundBar/Stereo Receiver while sharing ONE Digital Optical Port (See THIS ARTICLE for more details regarding this function.)

Here are the Instructions of Connecting using an Adapter:

1. Connect your Bluetooth adapter to Power.

2. Connect the Bluetooth adapter to the TV. Our adapters support Digital Optical (aka TOSLINK or SPDIF,) 3.5mm Auxiliary (aka Headphones Jack,) and RCA (Red/White) Audio Output Ports. Please see your adapter's user manual for more details.

3. Get your SENNHEISER Headphones into pairing mode (Please scroll to the bottom of the page or see your SENNHEISER user manual.)

4. Get your Bluetooth adapter into Bluetooth Pairing mode as well. Please see your user manual if you're not sure how.

5. Keep your SENNHEISER headphones close to the adapter until they connect.

6. Once connected, if you're using Digital Optical connection, please go to your TV settings menu and change your Digital Audio Format to PCM.

7. And you'd be good to go.
