I purchase these headphone to use while work out because I be tire of the ear bud that come with my ipod and other cheap ear bud fall out of my ear . these be amazingly comfortable and be very secure in the ear . as soon as I put they in I be very impressed . it be easy to figure out how they go in the ear and easy to change the provide tip to find the right size . there be also a small clip on the cable so I can clip the cable to my clothes so it do not bounce around during the workout . the sound quality be a amazing upgrade compare to the headphone I have be use but I be compare they to very cheap headphone . this be my first pair of nice headphone ever so I be not able to provide a comparison to other brand . I be concern about they durability , base on some other review , so I will update my review in a few month .
