AMAZING! I did 1 thing changed my rating from 1 to 5 stars. Remove the tape! There is blue transparent tape that insulates the earbud charging ports. If you don't remove it, the earbuds seem to die quickly and malfunction. Once the tape is removed, they are easy to use, have a long battery life, fit securely around the ear, and work just as well if not better than similar products that sell for over $100. The user manual can be difficult to understand due to translation difficulties, but it can be understood by someone that is not a stickler for English grammar. I am very glad I did not give up on this product due to initial difficulties. This product is an excellent bargain!
