I search out these earphone for purchase , after my dog chew on my last pair of sony becuase they give I a good sound quality and a great fit . I have a hard time find in-the-ear earphone that fit I comfortably . with some other pair they would get a cramped feeling after some time . with the different size cushion that be provide with the sony earphone , I could get a great fit . they block out background noise well and have a a nice range of sound . they also come with a nice little travel case which be good for have they with you and not get the cord all tangle on itself . I would recommend these for people that would like a good earphone for a really reasonable price .
