Picture of Bluetooth Headset Hack
My mum wanted to play some music from my desktop computer on her stereo(which doesnt have usb support but has stereo jack audio input) - and I was looking for reasons to hack stuff.
so i took  old broken bluetooth headset (that my ex broke...bla bla ) and  hacked it to include a stereo jack - and now she just plugs it in and plays the tunes(audio streaming) :)  

Future improvements:
1. Write a computer program to include voice control so she can just change music or switch of the computer off from her room using a voice command.
2.Hack the stereo to charge the bluetooth headset without unpluging it. (she probably wont let me do that lol )

Step 1: Schematic

great idea, did it with a stereo set I got at the discount store, works great. hooked them up with rca jacks instead so it would plug into my vintage stereo. I love bringing the 1960's and 2013 together.

I successfully made it but my woofer does not support it. Only the sound bar is working. Is it correct or should I make some changes?

Please help!

Hi, could you post more information about your hack e.g what you mean by sound bar etc
dex3844 (author)  dex38442 months ago
And which woofer you are using it for

Its philips home theatre

I connected a 3.5mm jack to the bluetooth headset with a wire. The wire is used for speaker in headset. Then I plugged the jack into the speakers(basically it is home theatre with a sound bar-which gives sound only, and a woofer-which provides bass). But the output is only sound with no bass!! Sound without bass is so creepy!

This is great idea! I have a ps3 blutooth earpiece that I'd love to do something with.

Here is my hack... a cheap samsung bluetooth headset which you can extend another earpiece from the charging slot... hacked the outputs from the charging port and connect a 3.55mm stereo plug... I can use my headset as it is and i can put the adaptor to use it on any amplifier or stereo with 3.55m aux input...

I sliced the cover of the stereo plug nicely so i can put it back after soldering the wires from the output...glued back with super glue and glued together with the adaptor,,,a little pain job and tadaaaaa!!!! looks descent...

great ible mate, i just have one problem with mine, my phone picks up the bluetooth kit for calls but wont allow me to play music via bluetooth to the same kit, the phone does allow music to be played through bluetooth just wont pick it up as a device for music

dex3844 (author)  twyeth11 months ago

Yeah I have tried my pc arms that picks it up for VOIP but struggles to let me use it for music purposes, unless using VLC player instead of media player

the Bluetooth is connect as only voice in desktop and mobile both. it wont play through that bluetooth . any solutions?

If you are using Android try the "BTmono" app. It will spoof media audio as voice audio and allow it to play through the headset. The sound won't be much better than phone call quality, though.

dex3844 (author)  rseth11 year ago

hi, try another headset and see if that plays - and what headset do you have by the way ?

dex - I have a stereo BT headset and would like to hookup a stereo jack to it so that i can use this to plug my stereo and also use this BT headset as usual when not in use with stereo. Please help.

dex3844 (author)  d-instructor1 year ago

which stereo BT headset do u have ?... you mean like some sort of way to remove the stereo jack when you don't need it /

I had this idea in mind and I am glad you did this to reality.

There are 3 major benefits of this idea:


  1. You can turn your desktop/laptop/cellphone to play music wirelessly on other stereo speakers (with audio jack) once BT paired wit this device.
  2. You can turn your car stereo into BT stereo.
  3. Those who would like to play music wirelessly using their android smartphone can use 'BT mono' android app.

Great job and nice gift for your mother! please don't forget to post your next idea to program this for voice control and charging the device :)

nice, so yours is stereo..which bluetooth speakers did you use?
muddog151 year ago
I am going to hack my Bluetooth speaker bar this way only I am going to have a cable coming off of it and have a switch to turn off the internal speakers on the sound bar.
muddog151 year ago
I just keep mine plugged in all the time so it doesn't drain the battery.
muddog151 year ago
I used RCA as well.

In the headset, wich wire goes with the black wire of the stereo jack? the red one or the black one?
dex3844 (author)  Pesoen2 years ago
Since the headset is mono - it doesn't matter - the black to black or the other way round will work the same
Pesoen dex38442 years ago
Thanks man! now it's working fine! This guy it's a genius!
dex3844 (author)  Pesoen2 years ago
no problem - glad I could help :)

And the the "bridge" is just soldering one wire to each conection and then soldering both to another wire?
dex3844 (author)  Pesoen2 years ago
yes it is - its just effectively making the connections into one
so i did it and it doesnt work only because my phone wont find it as a media player. it only works for the actual headset. any ideas about that?
why would your phone see it as a media player. It is simply a "bluetooth speaker". connect it exactly the same way as you would connect a headset over bluetooth, only instead of the headset producing the sound, you are having the headset pass sound into your stereo Aux port.

If the complaint is that after you connect it, your music does not come out, then that is a setting (or even limitation) of your phone. Phones expect a "headset" to be used for phone calls, not music, and may not even support playing anything other than phone calls through them. check your phone settings and see if there is an option for "primary sound device". If not, your phone will only understand how to send music through something it understands as headphones, the headphone jack, or an A2DP bluetooth device (stereo bluetooth for music).

great that it works to begin with but i dont know of a way to make your phone detect it as a 'media player' - sorry cudnt help you there but you could always use your computer :)

Amazing idea, glad to see it worked for you and other people. But if you make that 3.5mm Male into a 3.5mm Female, you can plu ANY headphones you want into it or you can put a small aux cable into it to get the same effect you have ^.^ just saying
dex3844 (author)  Gomex192 years ago
In theory it should work fine, but the sound level and quality would be affected more because of the increased resistance of the headphones or the aux cable- but that could be fixed by having a better bluetooth headset and adding an amplifier for the headphones,: still gud idea though and glad you like it
