for some reason I can not wear earbud headphone , I have try all kind and they be not comfortable and do not stay in my ear . so I have try just about every neckband and over ear design sport headphone out there ... until I find these and now I will never buy another type of headphone for run and work out . the Sennheiser pmx70 headphone be not only incredibly comfortable , durable and water\/sweatproof but they sound amazing . I be not expect the sound quality to be this high in a sport model . I have run many many mile in these through rain , wind , snow , sleet , etc. and they sound just as amazing as when I buy they -lrb- over a year ago -rrb- . I pay $ 50 for they and would do it again in a heartbeat even though I see the price have come down to about half that now . if you do not like earbud or can not wear they and need a sturdy , high quality sport headphone - this be it .
