Wireless headphones or a second life for Bluetooth headsets

This article is written for those who have accumulated a lot of electronic and broken junk at home, but it’s a shame to throw it away. I got everything for free and I only benefited from this homemade product.



And so I had Explay headphones and a Prolife BT55 stereo Bluetooth headset. The headphones, as you can see in the photo, did not have a wire, and the speakers on the headset wheezed. In the end, I decided to make one fully functional, and even necessary, item out of partially working ones.



We sort everything out. No screwdriver needed - snaps on. We remove the remaining wires from the headphones, and unsolder the speakers and temporarily the battery from the headset in order to pull the wiring out of the case.



As a result, after disassembling and sawing off unnecessary parts of the case, we were left with a block of buttons and filling from the headset.



Now we need to attach the button block to the headphone body. It turned out to be very easy to do. Having removed the cover with the name, I discovered that the space under it almost coincides in diameter with the block of buttons, I just need to remove the partition.



Having unscrewed the filling, I processed the body to the size of the lining.



And tried it on the headphone body.



In order to unsolder the mini-usb charging socket, I decided to make a small adapter from mini-usb to the socket from a Nokia mobile phone. The socket fits very well in the former hole for the wire.



I also drilled a small hole for the microphone.
After installing the board in place and securing it and the parts with hot glue, it turned out what you see.



Front view. I made a small mistake here. When drilling the hole for the microphone, the cartridge slightly touched the headphone body, but this was not noticeable at all.



Once the glue cooled, I soldered the speaker itself and closed the case.
I soldered the battery and the second speaker.



Once everything is soldered, the case is snapped into place, the foam pads are installed, we put it on charge to check and we see that everything works (the indicator lights up red)



Since the headphones are foldable and adjustable with a wire, I decided to leave it as is, simply throwing it over my head with the headphones on. I’ll also add that the sound has become several times better and more than one and a half times louder than the headset. All buttons and microphone work fully, which is very pleasing.
