two devices to one headphones

In theory you could try 2 male/female ‘three ring’ 3.5MM cables - basically a cable with a plug just like your headset has with the left/right and microphone connection ring and a Y that is female on the Y end and male on the two end and see if you can have each device think it’s the only thing plugged in.

Then plug your headset into the single female end

No idea if this frankenstein will work (and if you have lightning all I can suggest is search amazon)

Hello,

It is not possible to simultaneously connect one pair of headphones to multiple devices.
