I just got a job doing 3rd shift grocery stocking, usually they don't allow earbuds but there's no customers so everyone does it anyway.
I'd like to get something ~$30 or less (I don't really care about the sound quality so much as long as it doesn't sound terrible), and battery life lasting at least 8 hours. Wireless because I don't want the wire getting in the way of anything or feeling weird down my shirt.
Soundpeats Air3/Air3 HS. Usually under $50. They look Airpods knockoffs, but they're pretty good. I've had mine for about a year. Also doesn't completely seal just in case you need to hear your surroundings.
