Stream your TV audio to Bluetooth headphones.

  • TosBlue-X digital bluetooth 4.0 adapter for use with one pair of headphones.
  • Transmission range: 10–15 meters / 30–45 feet. 
  • Best aptX used

If you sit more than 2 meters away from your TV – the wonderful stereo sound is gone! To listen with one ear would be enough! But you have two! With two ears you can hear sound from different directions – in stereo, in other words.

The TosBlue Single unit is a specially designed stereo bluetooth transmitter. It is the main building block of our tvSoundCast Single concept.

The unit converts optical digital sound signals from your TV into stereo Bluetooth signals ( Toslink / SPDIF ). The signals are transmitted to any connected (paired) Bluetooth receiver, such as a Bluetooth headset or a Bluetooth speaker.

NOTE! Our BHX Bluetooth HiFi Stereo headset is designed to work seamlessly with the TosBlue unit

Connecting wireless headphones to your television is easy. Our TosBlue-X adapter is easy to install and ready for operation when your TV is. Use your own Bluetooth headphones (with aptX) or buy our tvSoundCast bundle (TosBlue X adapter + BHX Bluetooth headphones).

Here is what one customer says:

“We are using your product to connect a Vizio sound bar to our LG smart TV. It has completely transformed our viewing experience. Sound from the LG was muddled; we often could not understand the dialog. With TosBlue X and the sound bar, we now have movie theater quality sound. Your product is excellent!

No sound delay with aptX:

We have used the best aptX technology from CSR/Qualcomm: .

aptX ensures faster conversion of data by a hardware chip, rather than performing the conversion in software. The hardware conversion is much faster and ensures practically no sound delay in the conversion process. No delay is important when watching TV,  because you want the TV picture to be in sync with the sound from your Bluetooth headset or Bluetooth speaker.

Read more about aptX in our Blog post here. 

NOTE: To take advantage of aptX, both sender (TosBlue-X) and your Bluetooth receiver must be equipped with aptX, like our BHX headset.

ALSO NOTE:  If you have a nice Bluetooth receiver without aptX built in, it is possible to reduce – or in best case get rid of - the delay by a few tweaks. Please read more what you can do in the Blog post

This is how the unit works

Mount your TosBlue unit on back of your TV with Velcro pads. The top portion of the unit should be visible from the front, where you sit.
No tools or special knowledge are required. All cables and Velcro pads are included.

The unit is powered from your TV via the USB cable. So, when you turn ON your TV, the TosBlue-X unit will be turned on as well. An optical cable transmits the audio signals from your TV to the TosBlue unit. The cables are hidden behind your TV. 

So, when your TV is turned ON, the unit becomes active and converts the optical sound signals from your TV into wireless Bluetooth signals. The Bluetooth signals are transmitted to a Bluetooth receiver, for example a BHX Bluetooth headset from Telme2.

You may now choose to turn OFF the internal TV speakers. The sound level may be adjusted on the headset independent of the sound level from the internal TV speakers.

With the internal TV speakers OFF, the sound is just for you. Nobody around you will be disturbed.

A new sound TV experience! You will enjoy it!


How to use:

The use of the unit could not be easier. When you turn ON your TV, the unit receives power from the TV via the USB cable. So, when the TV is ON – the TosBlue-X unit becomes ready. 

After you have paired the unit with the Bluetooth receiver for the first time – you just turn your Bluetooth receiver ON, and pairing is done - automatically.

The video below shows the procedure in detail. Please watch. A complete User Guide is found here
