Introduction: 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
This is the circuit diagram
Step 2: Items Needed
You are going to need:
1. Bluetooth headset
2.Stereo jack(3.5mm)
3.Soldering iron and wire
5.Hot glue gun
4.Thin wire
5.General tools - e.g wire stripper
Step 3: Process
Take the cover off and be carefull with the small wires inside
Step 4: ...
strip of the casing of the stereo jack if needed to
Step 5:
Step 6: ...
Solder two wires to the stereo jack
- bridging the top 2 connections for left and right(black wire ) - then ground wire on third connection (white wire)
This is because the bluetooth headset has only two wires(mono output instead off stereo left and right )
*You might also want to snip off the microphone wires for privacy - but I didn't because I actually need that microphone for future hacks
Step 7: ...
Make a small hole on the headset cover and insert the stereo jack then glue it on with hot glue
Step 8: ...
Solder the wires from the stereo jack to the headset wires
be very careful because you might end up pulling the wires off like I did
Step 9: ...
Put the cover back and you have a finished product - tadaa!
Step 10: Finaly
Plug in your headset to the input(female stereo jack) of the stereo
Turn it on and pair it to your computer
Play some music

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.

because you are not using a matching speaker. probably the speaker you are using is much powerfull, therefore this circuit cant drive your speaker. you can use a cheap amplifier circuit as a fast solution. or you can find similar projects here, on instructables.

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

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...

thanks, its probably the headset you are using.. have you tried using a pc ?

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
