I've tried it a couple times. Conventional earbuds are more comfortable (Galaxy Buds or AirPods), but this was surprisingly usable in my case. It really depends on your sleeping position, and if you sleep on your back or on your side, it should be fine.
Awesome, hello tech enthusiast friend! :) I'm just a one man team for now, but I'd love to see reviews from you! Luckily, it's easier than ever to get started!
