Use Bluetooth Headphones with a Chromecast

A reader recently asked if he could continue to use his Bluetooth headphones after casting videos from his mobile device to his Google Chromecast streaming media player. I tried it out and discovered I couldn’t do it directly because as soon as I cast the video, the audio switched from my headphones to the TV.

I did some research and saw recommendations for some apps like LocalCast, but I tried installing it and haven’t yet figured out how to make it work. But then I discovered that as long as your TV has an Audio Out port, you can get an accessory to send the audio back to your wireless headpones.

I got this TaoTronics Bluetooth Transmitter to test it out and it worked easily and perfectly.

Note: Your Bluetooth headphones must support the A2DP Bluetooth technology. I have no idea what that means, but that’s what the little booklet that comes with the device says. If your headphones don’t support it, there may be other transmitters that you can use.

How to use the Bluetooth transmitter

All you need to do is plug the audio jack into your TV’s headphones or other Audio Out port. If your TV doesn’t have a single port, the device comes with an adapter for dual output ports. It also has a USB charging cable that you plug into the transmitter and then into a USB adapter (not included) to plug into the wall. I tried plugging it into a USB port on my TV but it didn’t seem to provide power to it.

Once it’s set up, you simply press the button on the transmitter until the light starts flashing blue and red, which means it’s in pairing mode. Then you follow the instructions for pairing your Bluetooth headphones to other devices and voila! You can now cast anything to your TV and listen to the audio through your headphones.

Note: If I no longer want to listen through my headphones, I need to unplug the transmitter from my TV. Simply turning it off doesn’t work. I’m not sure if this is a function of my TV specifically or whether it applies to all TVs.

Do you have another solution for listening to your Chromecast content through wireless headphones? If so, please share it in the comments.

  • Hi there,

    I need your assistance to resolve a doubt.

    I bought a pair of bluetooth headsets and a bluetooth transmitter, to listen to the tv from the headphones, without disturbing my companion while watching movies, games and TV series.

    When I connect the headphones to the transmitter - it connects immediately, without problems - audio is working normally.
    Audio is taken from the TV's RCA dual port -> transmitter -> headphone.

    However, when I change the input source via HDMI connected to Chromecast, the headphones remain on the television audio, so I can not hear the video audio in Chromecast.

    The same thing happens if I put on the other HDMI output, to which I connected my laptop. Audio stays on the television channel and I can not hear the video.

    Is there a way to overcome the problem? According to you how can I solve it?

    thanks guys

    • Hi Lorreca.

      Unfortunately, I'm currently unable to test this out myself. It sounds like you may need to change the Audio setting on your TV, though. Have you tried that?

  • I use mine alll the time by casting the whole desktop instead of just the tab and unchecking the "share audio" box before connecting. connect headsets to your oc and make sure they are set to play over speakers for media by right clicking on the speaker on the bar. boom!

    • Yes true but the audio is lagged as you are listening to the audio from your laptop versus the one that would be from your tv

      • If you have a decent Wifi connection with a decent router the lag should not be noticeable AT ALL.
        <0.1 MS ideally.

    • Hi Brian.

      Thanks for the tip! I'm not sure what you mean about "play over speakers for media", though. Also, are you talking about Bluetooth headphones or regular headphones plugged into your PC?

      - Elizabeth
