This review will not be published on this page but I'll vent anyway. First the sound is good but mine will not function properly when tapping on them. Their support sent me a PDF on instructions I already had and read several times. When I told them that they suggested I read them again. Then I got a second email from some other "tech" support LOL person asking me...is their something wrong with your earbuds? I can see this going nowhere fast and dealing with their customer support will only lead to frustration so I will be sending mine back for a refund.
