Introduction: Convert Any Headphones to Bluetooth Wireless

Picture of Convert Any Headphones to Bluetooth Wireless

The purpose of this instructable is to eliminate the headphone wire between my iPhone and headphones. The wire would constantly snag on things while at work and be ripped out from the headphones(3.5mm jack on the headphones). The "under the shirt" method worked however it was annoying at times and could still be caught on things.

Materials Used:
   1.  A pair of your favorite headphones* - I used my Studio Beats by Dr. Dre
*if your headphones do not have a 3.5mm jack on them, the headphone cord can be shortened permanently or just wrapped around the headband!

   2. Stereo Bluetooth Headset  (sound quality is great!! no hiss or crackle - good battery life)

   3. Short 3.5mm Stereo patch cable
I had one lying around the house that i purchased from Radio Shack ages ago.

4. A few Velcro cable ties

Now comes the fun part!

Step 1: Attach Bluetooth With Velcro Straps

Picture of Attach Bluetooth With Velcro Straps

Velcro straps were cut to fit around the band.
I put them on tight with fuzzy velcro side down - or - the side that contacts the headphone band

A shorter patch cable would be ideal but this works just fine.

I called my brother to test sound quality and he said that he could hear me fine, even with the location of the mic

Step 2: Works Perfectly!

I used it almost all day today and NOT ONE SNAG!!!!  yaaayyyy

Ok so i made this as well and i wont lie i was kind of in a rush and in turn there was a couple things i did differently!!! For example i chose not to cut my wire just in case i ever decided to use it for something else. So what i did was used heat shrink tubing..... basically to hid all the folds in the wire and i also used a unit that was both a receiver and a transmitter again because i have other uses for this bluetooth module so i didnt want it to be a perm headphone thing so its velcroed on there for easy removal for charging but also in case id like to use the bluetooth module elsewere!

Do you know any alternatives for the stereo bluetooth module that can connect to an USB headset?

jmackinac (author)2016-10-06

Is there any way to transmit and receive. For example, taking my Bose corded headphones, attached a receiver and then get a transmitter for my tv. I have googled this quite a bit and most just connect a receiver to corded headphones to use with a tv that's aready equipped with bluetooth transmitter

BainbridgeYew (author)2016-08-31

This may be a stupid question, but considering that most headphones do not have a battery in them, how does this work?

y2leon (author)BainbridgeYew2016-09-05

not stupid at all, the bluetooth receiver's battery can hold your headphones for 3 hours or more, i've been using the mth50x and this bluetooth receiver for more than one year now and still working fine.

y2leon (author)2015-03-09

Good instructable mate, here my black Ath m50x and my white Ath m50

Thanks for the idea!

GusF2 (author)y2leon2016-09-05


I know this is an old post, but I hope you get this message.

Where did you get the cord for the black headphones? They look like M50x or M40x, so I am assuming they use the small 2.5 mm connector to the headphone. I've been looking around for a couple of days and can't seem to find anything like that anywhere.


y2leon made it! (author)GusF22016-09-05

Yes the black are m50x.
Is the original cable shortened with a
plug from radioshack in the end, but now im using this cable
and this 2.5 to 3.5mm adpter
but you have to scrabble i little bit to fit the adaptor in the
hedphones (you lose the locking feature for the cable) sorry for my bad

Hotwired89 (author)y2leon2016-01-06

Looks great!!

lwang15 (author)y2leon2015-11-06

that looks great! how did you attach the receiver to the headphones by the way? velcro, or?

y2leon (author)lwang152015-12-28

I'm using 3m double sided tape and I had to paint the edges with a sharpie for the black ones

MinhD4 (author)y2leon2015-09-12

Plz teach me how u could do that. Did u have to cut the original cable to connect with the one of bluetooth receiver?

y2leon (author)MinhD42015-11-04


aldo.soto.10 (author)y2leon2015-04-16

wait, those look different from the post. what are those bluetooth called?

there are a plethora of Bluetooth receivers available for $20 or less on amazon. I recognize the MPOW one in the black picture, but not sure what the white is.

y2leon (author)nflemming20042015-11-04

Thats righ, both are Mpow from amazon, and the 3.5 plug is from radioshack

vkarthik3 (author)2016-03-27

Great tutorial. I got the MPOW and tried fitting on my bose quiet comfort 3. There is a small problem. When the headset's noise cancelation and the dongle are turned on, there is a static noise even if there is no music. Sometimes this does not happen. Any idea how to rectify?

bidomo (author)vkarthik32016-08-26

I have a very basic headset, a Corsair HS30 (3.5mm connector version), my mic is very poor quality, in normal conditions, people hear me with difficult, at night, it is even worse...

What I did was, install VoiceMeeter banana and the extra Virtual audio cables provided by the author of the software, amplified the mic gain to the max (+30db), activated noise reduction filter in my mic, and the proceeded to clean the noise with Adobe audition.

You can also do this with a free VST (there are some free programs that might do it), or you can try Audacity.

Check some tutorials in youtube, my mic has improved insanely, and people can hear me even if I badmouth them in a whisper.

JohnnyS50 (author)vkarthik32016-04-30

Unfortunately the only way to rectify that is to turn it off. There are several ways active noise cancellations work. One is that the headphones output some whitenoise. I'm guessing this is what you're hearing. The other way headphones do it is using another microphone to pick up ambient noise, and outputting the opposite waveform.

Hotwired89 (author)vkarthik32016-03-30

IT could be the cable you're using, I'd double check your connections first.

Ednil OgmandineB (author)2016-04-12

Do you need to cut the wire? Also how will the BT dongle's jack connect to the Headset

alexj53 (author)2016-02-22

Beautiful <A

DrunkenDwarf (author)2016-02-09

This looks like an awesome instructable and can't wait to try it. I have a headset I'd like to bluetooth, does anyone know a good (and cost effective) reciever/transmitter that'd work with that? I've found a few but they have switchable modes so can be in one state or another, for a headset it'd need to simultaniously receive the headphone signal while transmitting microphone audio.

mysterybee made it! (author)2016-01-13

PSB M4U 2 Headphones, MPOW Streambot Mini Receiver, and a short strip of hook & loop tape purchased from a local pharmacy.

Lightweight, convenient and oh so easy! Thanks to Hotwired89 for an inspired idea. Unfortunately, I can't use the receiver with the amplifier or noise-cancelling feature enabled on the headphones, but luckily my PSB headphones work just fine with the power switched off. If I can find a very short speaker line with an in-line microphone, I may modify the solution accordingly.... but for now I'm very happy that I can listen to my music, adjust volume, change songs or pause all without reaching for my cell phone!

Hotwired89 (author)mysterybee2016-01-19

Hi Mysterybee! Those looks great, nice job. If you scroll through the comments I proposed a solution to your problem with the noise cancelling. Thanks for making it!

DylanM31 made it! (author)2016-01-10

Thanks! Very Good.

OsianoI (author)DylanM312016-01-15

Hello DylanM31. I have the same pair of headphones and wanted to ask how you braided the standard cable to such a short length for this project. Or, how you shortened them.

The difficulty with these headphones are the naturally long wires that make wrapping them around undesirable and the lack of a standard 3.5mm jack. However, your take on the design manages to circumvent these issues and look stylish while doing so.

Thanks for any help!

Hotwired89 (author)DylanM312016-01-11

Nice work DylanM31 with the cable braiding! There are short patch cables like you have used but one end has a 90 degree-3.5mm plug if you were looking to remove the hard bend in the cable.

mysterybee (author)2016-01-04

I have a pair of PSB M4U 2 Noise-Cancelling headphones. I've bought an MPOW Strreambot mini bluetooth receiver to connect with it. It works beautifully except whent the noise-cancelling is switched on. Then the music stops. I've tinkered with it a bit and discovered that the music works with noise-cancelling when I'm using the 3.5mm 4 pole cable that comes with the headphones. The 4 pole cable has a mike connection switch on the cable. I suspect that has something to do with it. So now, how do I make it so my bluetooth receiver works when the noise cancelling is switched on? 6" long 3.5mm 4 pole male-to-male connectors apparently do not grow on trees. Any ideas?

Hotwired89 (author)mysterybee2016-01-06

Hmmm... sounds like the headphones are using the built in mic on your "stock" cable to pick up ambient noise for the noise cancelling process. I doubt there's an off the shelf product to remedy this. If your handy with a soldering iron you would make your own cable or pick up a second stock cable and modify that one. You would need to keep the microphone on the cable in-line with the Bluetooth receiver. 4-pole plug for the headphone size which carries the mic ambient audio and you can just use a 3-pole plug for the Bluetooth receiver side(stereo audio).

Try this quick test. Plug in your stock cable to the headset but then plug the other end of your headphone cable into the Bluetooth receiver. Switch on the noise cancelling and see if that works! Then report back of course!

mysterybee (author)Hotwired892016-01-07

Hey Hotwired, As you predicted the receiver works fine when connected to the original cable, but as it happens these headphones have two stock cables provided. Now I just need to know how to shorten one.

Hotwired89 (author)mysterybee2016-01-07

I researched a bit on the process of shortening headphone cables. It is possible to shorten a donor cable to the length you need and keep the mic in-line. But it would be a bit of a pain with the small thin wires present inside the main headphone wire. I have an alternate solution which in theory should work and won't involve any soldering, but it won't be as pretty looking as a short custom cable.

A headset "splitter" will separate your 4 prong plug in your headphones out to stereo 3 prong and 2 prong mic plugs. This will allow you to add on a small short mic to the splitter and still connect the Bluetooth receiver with the male to male adapter supplied with it. (At least the one I saw of your model was marketed as coming with this, otherwise you will need a small adapter)

This essentially creates the short patch cable you need to connect the Bluetooth receiver to the headphones but with a mic in-line feeding the headset for noise cancelling. I can't guarantee this will work or if the headphones will "noise cancel" properly as you'd be using an alternate mic for the input.



You can use a different brand splitter or mic as you like. Just be sure to plug the 4 prong into the headphones. The mic into the plug labeled mic and use the Bluetooth male-male adapter for the splitter plug labeled headphone.

If need be I can try to explain this differently or draw up a sweet MS Paint diagram for you :).

As always, report back if you give this a go!

Wondering if this has been tested with video output for lag? I'm looking to make a transmitter/receiver system so I can listen to my TV on any headphones

Hotwired89 (author)nflemming20042016-01-06

Shouldn't be too much lag if at all noticeable. If anything I'd be more concerned about range. But then again how far would you be from your TV? At most, just in the other room!

nflemming2004 (author)Hotwired892016-01-06

The lag would stem from the conversion of the analog audio signal and then back after the Bluetooth signal reaches the receiver. Compared to a pure analog transmission (such as using an FM transmitter/receiver) there would be some lag, though audio quality would be undeniably better.

y2leon made it! (author)2015-12-28

forgot to hit the I Made It! button Lol

Hotwired89 (author)y2leon2016-01-06

Awesome thanks for coming back to hit the MadeIt button!

Azim Alif (author)2015-06-25

I built one too!
Although mine dosent look that good, but, still works.

Also, I would really like to see someone build a device that can take audio signal from any 3.5 mm output, and turn it to bluetooth output.
so that any audio device can connect to bluetooth speakers, headphones.
If anyone knows about this type of device, please tell me. even if I have to buy it.

Hotwired89 (author)Azim Alif2016-01-06

What your referring to is a Bluetooth "Transmitter". You want to take an audio signal and convert/transmit it via Bluetooth! (This instructable takes audio "from Bluetooth" and converts it back to analog for a non-Bluetooth headphone.) A quick search and I've come across this. "GOgroove - Bluegate Audio Transmitter" listed on BestBuy (

Hope that helps!

cjoel made it! (author)2015-12-11

I made this a couple of months ago with a Bluetooth transmitter off AliExpress, it works great. Thanks for the inspiration!

Hotwired89 (author)cjoel2016-01-06

Nice clean install! Inside the band too for lower profile!

MageE1 (author)2015-11-30

would this work for it? -->

y2leon (author)MageE12015-12-28

yeah but you can find something with bluetooth 4.0

kimbo-fitzy (author)2015-09-28

this is great, just did the same thing inside my motorbike helmet with an old xbox headset, it works amazingly, thanks!!

HussainW (author)2015-09-02

Will the transmitter device affect the headphone sound qualitu???

devicemodder (author)2015-07-04

Where can i find a 3.5mm to bluetooth transmitter? i want to use it with my cassette walkman.

mahziard (author)2015-03-27

i must do this with my razer electra

pgeorge-michael (author)2011-11-01

I found the bluetooth headset here with cheaper shipping:

Curious how well it would work with a mac laptop - any experience there?

Me too ! But TV rather than the Mac Book.
