The soles peeled off while there was still a bit of tread left but they were already getting too thin to wear much longer. Certainly there are higher end products from Japan and Germany that produce superior sound quality, but I think at this price point this product is hard to beat. They give good grip on slippy surfaces include seaweed and probably a little bit of protection against weever fish. We have specialty vinyl siding. By saying this I mean it is tight, but not too difficult to put on. The clip is super nice as well and had room for my smart tag. The 2 characters are an unlikely pair, Molina an effeminate homosexual and Valentin a member of a guerrilla organistion. They do great noise cancellation, have great sound quality, and are also very comfortable in my ear. Update#1: charging case failed after 3 days- returning for exchange1st review:Longer battery life, can use either bud by itself- a REAL UPGRADE! The battery life is ridiculously long!
