Are there headphones with a detachable cable and wireless operation?

Question

Headphones

I must say right away that requests like "earphones wireless with detached cable" did not help, the results come out with a bluetooth cable that connects both headphones, and not with the usual 3.5 minijack.
I am looking for earplugs with a detachable cable that could be connected via a minijack to a device + with the possibility of wireless operation of headphones without a cable.
What it is for: so that you can listen to the headphones and charge them when there is such an opportunity.
The duration of work, the range, of course, are important, but I would like to know if there is a term for such headphones, and mb some examples.

Answer 1

It seems that your search is in vain, because here you also need to have a 3.5 mm minijack on the side of the headphones, and with such a plug, the earpiece becomes twice as thick and does not fit in your ear. I regularly browse Aliexpress (Hot Products) and have never seen anything like this. I think that even if such a plug is placed on the suspension along with a microphone and a battery, the suspension will become much thicker and, with its weight plus the weight of a thicker cable, will pull the headphones out of the ears (the cable with two minijacks is much thicker than the usual headphone one).

Answer 2

If you only need to charge while listening, then technically I don't see a problem. I don’t know specific models, but a middle-class radio amateur may well make such a collective farm. There the only difficulty is miniaturization.

Fiio has released a device that allows you to turn any headphones with a detachable cable wireless
