- No dangling wires
- Nothing irritating my ear canals (I can’t stand earbuds for more than 20 minutes, they’re unbearable)
- Ability to hear naturally and get external audio at the same time
- Inconspicuous - as in, listen to an interesting podcast discreetly in a meeting that bores the shit out of me
- Hacking potential
- Shit, it’s just cool
What a strange comment though: it’s like asking why one would implant a RFID transponder when a card can do the job
