I bought these buds after reading the generally positive reviews that it had. The price was decent, it costed just over 15 bucks. That also reflected the quality of the buds however. I have used these in the office + @ home and never went running with them or to specifically hazardous locales. I have always kept them in the soft bag they had come with when not using them. The outcome was a pair of broken buds that are obviously not worth the price after only one month of usage. (late june - late july).
The damage is also not even visible. It has occurred at the end of the cord where it is plugged into a device. Something inside the small plastic cyclinder is broken (faulty wire is likely) because I constantly have either earbud shut off on me (which includes both simualtaneously) when using them. Amazingly this is just after the 30 day refund period so now I have stuck with broken buds for reasons that appear to be related to build quality.
I will not be buying another product from Coby Electronics as-is. This was a disappointment for buds that have decent sound quality. They suffered in another sense I suppose.
