Bone induction headphones are great, but I agree with
@trecile and
@C clearly that they're not the most comfortable option for sleeping.
I am constantly on the lookout for a solution to wearing headphones to help me sleep. I tried one of the
Bluetooth headband headphones for sale on Amazon — there are dozens of "brands" with slightly different styles but they're all pretty much the same item — but they were much too tight and uncomfortable on my big head. So I've just settled on the same AirPod Pros that I use for daytime listening and phone calls, with the addition of a
silicone keeper strap to keep the headphones from getting lost should they pop out of my ears during the night. (I have a pair of wired foam tip ones like the ones
@trecile describes above, but prefer to only pack one pair during my travels for the sake of simplicity.) AirPod Pros also have a "transparency" mode that allow background and ambient sounds to be heard while you're listening to something else, so I'm only completely sound isolated when I want to be.
As a side sleeper, I found that replacing the AirPod silicone tips with
third party memory foam ones makes them more comfortable for sleeping. I usually set a sleep timer for my music/sound app so they're not running all night, but even if they deplete a quick top-up while I'm brushing my teeth keeps them powered up for the rest of the day.
(This might also be an opportunity to bring up my long-held belief that sleeping in shared accommodations would be easier and more pleasant for everyone if albergues installed some
simple white noise machines to drown out the assorted sounds of sniflling, coughing, snoring, and ... the rest. The "silence" when the lights go out is truly deafening, and every rustle and creak from another bed sounds much louder than it actually is. But maybe that's a subject for another thread
