You could basically do this with any Headset & Bluetooth Headset combo there is. I used a spare headset that was laying around and recently purchased a cheap (roughly 30$) Bluetooth headpiece. More specifically These.
Basically all you need to do is open it up and locate the wires that are soldered to the actual earpieces, remove them from the Bluetooth one and replace the Wired Headset wires with them and you should be good to go!
It’s a simple switch-a-roo trickery with wires, just be sure to check which one is the signal wire and which is the ground, I’m not sure what happens if you mix them up, but surely nothing good can come of it.
