Yes, I know IFEs don't support bluetooth, please read the post before pointing this out!
I am looking to find a way to connect bluetooth headphones to the IFE in an aircraft, this would require bluetooth-enabling the audio output of the IFE. My first thought was to get a bluetooth to 3.5mm adapter like this (with an airline headphone to single 3.5mm adapter):

I've used these before, but in a brain fart I didn't realise this device would be transmitting to the headphones, not receiving from an audio source, which is what they're designed for. There's also no screen and thus no way to pair to the headphones.
There don't appear to be any 3.5mm to Bluetooth transmitters on the market, and the pairing issue remains. This leaves two options:
Use an Android Phone or a Windows laptop as a transmitter. However I'm not sure this is possible. This is where I am so far:
An aux cable from IFE to phone won't work as it won't have the TRRS connector to feed the mic in the phone. There are apps to transmit the phone mic to bluetooth, and to record from external mic. Whether these apps can transmit external mic to bluetooth is also a question. The issue is to get the TRRS connector fed from the IFE.
It seems the only way to do this is to use a 3.5mm TRRS male to RCA female, and from the IFE have the 2-to-1 adapter then a 3.5mm male to RCA female.
Another option is to use USB (complication: my phone has USB Type C). This all depends on these transmitter apps being able to even use an external audio source and not just the built-in mic.
Anyway, long post short: Has anyone ever experimented with any of this and/or had any success?
