Right bud died on several pairs... Caveat emptor
Sound is great. Very comfortable. That much I will give them.Part of the problem, though, is the overly long cord. If you exercise, you will inevitably pull on that cord.First pair I bought, right bud faded and then promptly died after about three months.Must have just been a bad pair, I reasoned. Took a gamble and bought another pair because I liked the sound and comfort.Same thing happened with the second pair.Third pair's right bud kicked out after about two months.Lesson learned. Don't think you will be a lucky one to whom this doesn't happen. Avoid these ear buds.
