the sound quality and bass of these bud be very good ... if you can actually get they to stay in you ear for more than 2 minute at a time . definitely do not plan on be able to wear these walk or run . even sit down , they fall out of my ear after barely turn my head . they do come with 7 different ear piece to try out , but the main problem arise from the clunky design of the earbud itself . the oversized cylinder shape of the bud prevent they from fitting nicely in the ear canal , regardless of which of the 7 ear piece you use . I should also mention that because of the poor fit , there be almost no ambient noise cancellation . and of course , in the slightest breeze there will be load of wind noise howl in you ear . another draw back be the huge piece of plastic\/rubber that serve as the separator for the left and right cable . this constantly get catch on thing and help pull the earbud out of my ear even faster .
