I have had these headphones for over a year and use them mainly for jogging/running, usually 4x/week and at least 15-20 miles per week. I like the fact that they are water resistant. The sound quality was good for the price but not great (but who needs great while exercising anyway). Comfort is great and these are one of the few in-ear headphones that haven't given me headaches after hours of use.The only reason I don't rate them 5 stars is the weather finally caught up to them. After running multiples times in rain, humid weather, etc. one side has finally gone bad (left). I can still use them but the sound from the left side is very faint.I will purchase the same type again but am looking for slightly better sound quality. But who knows, over one year of getting rained and sweated on isn't a bad track record for a pair of $20 headphones.
