Purchased several years ago. This is a junk item, please purchase with the understanding that it requires repair. (Symptoms) ・Red light turns on when charging. ・Generates heat when charging. ・Only the right earbud cannot be charged. This is all I know at the moment. I will also include the silicone case, the original box, and the warranty. *The earbuds themselves do not have ear tips attached. Please comment if you have any questions.
