Update 4/26/2020 These things came with a 100% charge and with off and on use they still have 80% and Im still amazed by these things. They fit in my ears and stay in even while running. Its close to my washer & dryer, so its ALSO useful when I remove clothes from the dryer. Pratici da usare, basta un tocco col dito per regolare il volume e cambiare traccia. whouaa, trop simple. There?s nothing notable to say about these, period. So sandals came in. So I?m writing a review. They are very comfortable and wide enough for my wide feet. At first I was iffy about the shape of the ear tubes but they balance and rest very well.
