is it possible to take a 3.5mm headphone extender thingy like this one and cutting it into 2 pieces taking each end and soldering on bluetooth thing on each piece and making it work and send audio signal through it. so you plug one thing into the headphone and one thing into the pc and have a semi-wireless headphones?

could this work?
or can you buy something that works likes this?
 
in theory, yes.
In practice, it gets messy easily. Main problem is that both receiver and sender would need power, so either connection through micro-usb or internal battery.
something with battery already exists:

Edit: The problem with that is that it works either as transmitter OR receiver and it's documentation makes no mention if it can pair up with second piece of itself (implying you buy two)
If it can, buying two would pretty much do what you want at around 38USD
Edit3: According to q/a from seller, it can pair up with itself so if you buy two, it's ready and working.

Another "cut the cables completely" option would be to get bluetooth adapter for the computer end and bluetooth headset.

getting your own buetooth transmitter and recever modules and soldering them on the cable ends would be possible too but cost would be above the two example items AND said chips would still need power.
edit2: Also said bluetooth modules are kind of "dumb side" in a sense that you would need a pc or phone to initiate the pairing and as such they don't really pair up with each other.
 
As description tells, kind of.
It has 3.5mm jack for headphones.
It has microphone in it (it will not support microphone in headphones if those exist, then again other bluetooth toys don't either)
it needs to connect to phone or other things you use it with through bluetooth.
if you buy separate usb bluetooth dongle for the PC, it would allow you to work with it.

so kind of lacks the original posts 3.5mm jack->bluetooth part of 3.5mm jack->bluetooth->3.5mm jack->headphones
 
You're asking the wrong question, I suppose. Why you insist on Bluetooth? If your problem is connecting an existing wired headset (headphones and microphone) to existing apparatus (CB radio comes into my mid), than ask the question that way. If you want to connect a headset to a computer/laptop/phone, this is entirely different question.

So, let start with that - what do you really want to connect, and where to?
