Get into wireless headphones you’ll never look back, and don’t play the audiophile card it’s so pretentious.
Sure, It's just a good job that nobody uses their Mac or iPad for, e.g. music or audio production (be it professional, pro-sumer, amateur or purely for personal satisfaction), where the inevitable significant-fraction-of-a-second delay caused by wireless headphones makes them about as much use as a chocolate teapot (yes, you can delay
recorded video or a piano-roll display to compensate for latency, but plug a keyboard or microphone in and that kinda requires a time machine).
There's huge potential for iPhones and iPads in this area, and a host of excellent products available but they're already hamstrung by the limited connectivity (they all depend on the "camera adapter" that gives you 1 USB and a
charge-only lightning port, leaving you nowhere to plug your lightning headphones).
Then you end up with your bluetooth headphones for just listening to pre-recorded stuff, your lightning headphones to plug into your iDevice, your USB-C headphones to plug into your Mac (fortunately, sanity has prevailed so far with Mac headphone jacks) and your analog headphones to plug into other equipment... (there are a few models of 3.5mm/wireless headphones out there - but not much choice... or there's always more dongles).
