I like these because I can watch something on my iPad, listen to Podcasts, etc. and not have to worry about earphones falling out or bigger headphones being uncomfortable if I fall asleep. Besides helping to block out hospital noises, they help block out snoring husbands so I use them nightly. I set a timer on a Podcast to help me drift off to sleep (AppleInsider or Young House Love Has a Podcast; they’re interesting enough for me to keep my thoughts from wandering but don’t excite my mind like true crime does).
These are wired with a 3.5mm stereo plug. I use these because Bluetooth ones are just another thing to remember to charge. Also, my iPad is old and I just use the adapter to connect to my iPhone. If you tend to roll around a lot I’d recommend a Bluetooth version though because the cord can get tangled/wrapped around you.
