hello, I've just joined this forum and would be grateful for any advice on in-earphones. I've bought three Sennheiser CX500 in the past 6 month and they all stopped working (one ear gone) within less than two months. I'm not sure if they are fake ( from Amazon market place), I guess they, probably, are, but I love the CX500 and tried my luck again n again. I'm very short of money and can't keep buying earphones all the time. Can anyone recommend in-earphones that are as comfortable as the CX500 (I sleep with them!), I use mainly for audio books, not for music and my main concern is, after comfort, durability and price. I'm hoping not to pay more than about £25. I heard about the SoundMagic PL11 but I think they are over the ear? If so I don't know they're good for sleep with. And where can we buy genuine Sennheiser earphones? In case I take the risk again... Thank you!
