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.
id like them to use on planes but they start to hurt my ears(like they arent the right shape) after a couple hours so i have Sony WXM4000 or whatever for long trips. over hear headphones are always way better for comfort.
