I wish I could give less then one star. I bought a headset h800 it will not stay charged I sent it two support tickets because no one would answer me. The first one came back three weeks later the second one two weeks. All the sent me was a apology and links to faq pages and customer forums. So they left it up to me to fix, these are only a little over a month old so now I have $100 in these headphones twice as much as they are worth. I will never buy another thing from these crooks!
