Batteries last for a while if you let the case share fully when you first get it. Sound quality is pretty good. the split second you take the left earbud out and the sound cuts out completely only bothered me for as long as it lasted. However, the material/quality of the rubber part you stick into your ear is a bit uncomfortable. I switched mine out with some old ones I’ve had laying around which did the trick. All in all great purchase for the price!
