Battery life sucks. The way you have to pair them both separately is annoying. Most of the time one will come on without the other. Now only one earbud works at all. I’m so incredibly disappointed in these. I got these and I got a pair of Beben ones to try out. The Beben ones are 250% better. You can see the battery life on the ear buds. You can see the battery life when charging. Also the case is a charging case and I only have to charge them twice a week. And I use them a lot for work. Heck even the dollar store pair I got for my son to use while mowing last longer and works better then these kurdene pair. There are tons out there around the same price. Don’t get these!
