A few weeks ago, I was using my wired headphones when the headphones completely died on me. I found a small tear in the rubber near the stereo jack and found that these headphones were now useless.
Now I am in need of a new headphone, but feel that if I get a new pair of wired headphones, the same thing will happen again. I now, prefer to use wireless headphones only.
My electric piano has an output where I can plug in a stereo jack (wired headphones). Now that I have only Bluetooth headphones, I can't use it with my piano because my piano is not a Bluetooth device.
I am planning to make a small Bluetooth device that can use a stereo jack to connect to my piano, get the sound and transmit it to my Bluetooth headphones. Just want to know if a Bluetooth device is capable of capturing sound produced by a device, and sending it to a Bluetooth speaker or headphone. If so, please give me as much information as possible on how I would wire and program everything.
Buy a new stereo jack, deisolate the cable and solder it to the new stereo jack. Pay attention to how You treat cables! All equipment depends on cables one way or the other.
By all means, in order to play with electronics, goo ahead. There are modules ready to use, a lot easier to set up and run compared to build Your own transmitter and receiver involving plenty of voulnerable cables.
Most cheap earphone cables I’ve seen are not user repairable. The conductors, sheilding and insulation are all co-extruded, and nearly impossible to isolate. Buy a new pair while you build your project.
I did try to search on Google, but most people made their own bluetooth headphones that could RECIEVE sound from a preexisting bluetooth device, such as a phone. But, I want my bluetooth device to TRANSMIT a sound played from my piano, to a preexisting bluetooth headphone. Any ideas on, if I can do this?
If the sound output is digitial, your Arduino may be able to relay it into Bluetooth.
If the sound output is analog, no chance (max ADC sampling rate is 9.6 kHz at 10 bits - not enough for audio).

Do you know what the circuit diagram would look like? I am planning to use a stereo jack, an arduino UNO and a bluetooth module.
So you expect to get a digital signal? Make sure you know the voltage levels used; if the right level you can connect it directly to a digital pin, also connect grounds.
Make sure you know the protocol used, and that you can actually decode it properly into whatever BT audio needs to be.
BT module don't know, depends on the module. HC-05 uses Serial communication, likely too slow for this kind of application.

As wolframore said, these device are dirt cheap to buy, I don't see a reason for DIY.
