I purchase these headphone to use in the gym . for under $ 10 I figure it be worth a chance . my klipsch s4 's be not stay put so despite they excellent sound quality I want to try something that would even if it mean less quality . besides the Klipsch phone I have use shure , Ultimate Ears , Senheisers , Sonys , Koss ... . . you name it and I have probably try they . these phone match up pretty well as gym phone . nice fit -lrb- better than most -rrb- , good sound and durable . for $ 10 it be a no brainier ! just buy they , period !
