Everything was fine at delivery. I bought these for my child and they are a very suitable target considering the quality. The sound quality was never great, but they worked fine for a few months. Then one of them just stopped making noises other than the beeping when turned on and off. I contacted support and explained everything. They explained that they were fully charged. I received a reply message that made little grammatical sense, but wondered if I could try stressing it. I just bought another brand of Revain instead of trying again to explain what I have already explained. I was amazed at how much better the new ones were in terms of sound quality. In short, they are toys. They break like toys.
