I am on my third UE Boom. I have a background in digital film making and sound editing. I handle my equipment with care. No drops, no spilling, no kicking around. Nevertheless, all of my 3 Ultimate Ears booms lasted only for about 1 year, not even that. They look cool, but always same story: Without any apparent reason, from one day to another, they stop working properly and instead put out tinny, clanking, and weak sound. Sometimes it helps, when Bluetooth gets rebooted. I am done with this brand. Don't know what the quality issues are, given thousands of great reviews. Either, they are selling counterfeits here on Amazon, which I happened to get, or the speakers are really built not to be durable.
They break down after 1 Year
