Requirements for Bluetooth Transmission of TV Audio
- The TV supports Bluetooth audio output.
- The Bluetooth headphones, hearing aids, or speakers support Bluetooth audio.
Important: The Bluetooth logo alone is not sufficient proof. What matters is which Bluetooth functions and audio profiles the device supports. You can find this information in the user manual or the manufacturer's technical specifications.
If your TV cannot send Bluetooth audio:
If your TV does not support Bluetooth audio output, you can retrofit this function with a Bluetooth transmitter. This is connected to an available audio output, for example:
- Headphone output
- RCA output
- Optical output (Toslink)
- HDMI ARC/eARC (depending on the adapter)
Then you connect your Bluetooth headphones or compatible hearing aids to the transmitter.
Transmit TV Audio to Bluetooth Headphones
If your TV can send Bluetooth audio, the connection is made directly between the TV and the headphones.
Connection with a Bluetooth Transmitter
- Connect the Bluetooth transmitter to the TV.
- Turn on the transmitter.
- Put the Bluetooth headphones into pairing mode.
- Pair both devices with each other.
After successful connection, the TV audio will be transmitted to the headphones.
Transmit TV Audio to Hearing Aids
Many modern hearing aids support Bluetooth. However, whether a direct connection to the TV is possible depends on the specific hearing aid model and its Bluetooth standard. Not every Bluetooth hearing aid can receive TV audio directly from a TV. Often, a special TV adapter from the hearing aid manufacturer is required.
Before purchasing, you should check:
- Do the hearing aids support Bluetooth audio?
- Is a direct connection to the TV possible?
- Is a TV adapter from the hearing aid manufacturer required?
- Do the hearing aids support modern standards such as Bluetooth LE Audio or Auracast?
Can I transmit TV audio simultaneously to a hearing aid and a sound system?
Whether simultaneous playback is possible depends on the TV, hearing aid, and sound system. Some TVs support multiple audio outputs simultaneously. However, many models allow only one audio output to be used at a time. This should be checked in the TV's user manual.
If TV audio should be transmitted simultaneously to:
- a hearing aid and
- a soundbar or AV receiver
an additional HDMI ARC audio solution may be required. In this case, the audio signal is tapped for the hearing aid transmitter while the soundbar continues to receive the audio. The volume can then be controlled independently.
Alternative:
The FeinTech HDMI ARC Audio TV Adapter can provide the audio signal from a TV via HDMI ARC and simultaneously pass it on to other audio devices. A compatible hearing aid transmitter or Bluetooth transmitter can then be connected to this audio signal.
Important: The adapter itself does not transmit Bluetooth.
Which Bluetooth Adapter is Suitable?
| Device | Bluetooth Transmit | Bluetooth Receive | Typical Use |
|---|---|---|---|
| FeinTech BT200 | ✓ | – | Transmit TV audio to Bluetooth headphones |
| FeinTech Bluetooth Audio System | ✓ | ✓ | Use Bluetooth headphones and retrofit stereo system with Bluetooth |
| FeinTech HDMI Audio Extractor Bluetooth | ✓ | – | Tap TV audio via HDMI and transmit via Bluetooth |
Alternatively, comparable Bluetooth adapters from other manufacturers can also be used.
Notes on Bluetooth, Latency, and Auracast
With Bluetooth audio, a slight delay can occur due to wireless transmission. When listening simultaneously via speakers and Bluetooth, this can be perceived as an echo or reverberation.
Modern audio technologies such as aptX Adaptive or Bluetooth LE Audio can reduce the perceived delay. Auracast is based on Bluetooth LE Audio and additionally allows the transmission of an audio signal to multiple compatible receivers simultaneously. This makes corresponding solutions especially suitable for hearing aids, headphones, and shared listening.
