well as the title say , `` I can not stand these '' . I have use they three time and during all 3 attempt of use , they never stay on my ear . they just keep fall off . I `` m not sure if they be make for giant ear or what but while try to eat lunch and listen to podcast one afternoon , I spend more time put they back on my ear rather eat my burger . with each chew they wiggle a little further off till I have to readjust they every minute -lrb- no lie -rrb- . so unless you have giant ear I would stay away . I cant attest to sound quality because they would not stay on my ear long enough for I to judge . I would however suggest for a few dollar more the philip adjustable earhook headsphone shs4840\/28 . much better and adjustable
