The headphones last forever before needing charged(like 32-40hrs of playing time). Blocks out almost everything as far as noise and very easy to use. Love mine and already bought a 2nd pair as a gift. Go get you a pair
I didn't realize earbuds could sound so good. I have these about 3 Wks now and have tried them back to back with fairly high end wired headphones... These J labs are my favorite just excellent.
