Making wireless headphones

Pro Member Captain
Kareem El-Sadi (crosscheck9) Captain

Hello all,
I've recently decided to undertake a project in which I transform ordinary headphones, to wireless headphones. I have various reasons for this, however, I cannot afford to buy a good set. Now theoretically, I can strip the wires of a set of headphones and attach a transmitting device. With the jack connected into the mp3 player and a transmitter on the other end, I'd be able to transmit the music to my receiver, which is connected to the actual earpiece part. To do this, I'd probably need to implement bluetooth technology, but I'm not sure. Here's the thing...How can I get a transmitter and a receiver capable of such a task. I'm not sure if I'm going about this the right way, seeing as how my education in such fields is limited, but what the hay', I'll give it a try.

I know absolutely nothing about it, so don't know whether this could be of any use at all....

Hey crossheck,I think I can help you a bit if we keep in close contact via pm or chat.You'll need 2 radio chips,one receiver(for the headset) and one transmitter(for the jack on th mp3).

I can also help you, as I'm a know-it-all in electronics.

Ok, first thing, you must know the basics, you need a transmitter and a reciever, and BOTH need to be powered (i.e. battery).

You can get them in a cheap electronics shop (but don't expect to have good quality).

You'll need an amplifier, to connect to the transmitter (like this: audio signal > amplifier > transmitter), and to set the transmitter and reciever to the same frequency.

What I can suggest is buying a small FM transmitter kit with a small range (80m and below is legal, I believe) and modify itso you'll get signal from your mp3 unit, and buy these FM-headphones old people seem to fancy.

Tell me if you need any further help man! I can also help you via the IM it's no challenge.

Well thank you all very much for the help 😀

As far as getting a transmitter and receiver, I have an old set of "walkie-talkies"...if I dismantled them and used their parts, would it work?

Also, what kind of amplifier would I need? How can I get my hands on one?

I greatly appreciate your help

I was going to suggest that.Now pilau probably knows more than me, but i would like to help too.
Disassemble the walkie talkies(using brute force if you must,and you won't ever need them again) but don't damage the electronic circuit board inside.take pictures of it from both sides(the elctric board, that is)and send them here. I'm not sure you'll be able to use the transmitter & receiver inside, so don't damage it if you end up wanting to assemble it again.

i like the way this is going 😎

I did that trick with the walkie-talkies a while back for my electric guitar. Still have it, although I don't use it cause the quality is cr*p.

I did have an automatic distortion effect though, that rocked 😀

I suggest you try it anyway, just for the experience, it should be very cool!
What you need to do is get something to press on the "talk" button on one of the talkies constantly, so it will always be transmitting.

All the other stuff you already know and in case you need anything, just ask! 🙂

Not really.You can just cut out the switch and conect the two connections where it was with a piece of wire(electric wire).

Pilau Guest

True. I forgot that cheap walkie-talkies have cheap circuit boards, so it's easy to remove any parts from it. Ever tryied removing any part from a motherboard? That's one hell of a challenge.

Anyway, when you get to this, take a look at the switch, because it might have multiple connections (in my walkie talkie it had eight connecitons), just so you'll know to plug everything right.

YEAH!!!!!Hard!!! Yeah, crosscheck, you might want to take and upload a picture of each side of the circuit board, so that we can supervise.

I'm very pleased to see the enthusiasm. Thank you all for the advice. Unfortunately, I'll only be able to start this mini-project after September 1st, because I'm on vacation right now, and I don't have the necessary equipment. I'll be sure to bring this topic back up when the time is right, however, just to double check, where can I get the amplifier...can that also be found in the walkie-talkies. I think it would, because they carry out the same tasks...transmit sound to another device, so it would probably use an amplifier aswell, correct?

Pilau Guest

Yeah, of course. The talkies have an amplifier. It's that knob you turn 🙂

Yeah, for the volume.
