I am looking for some advice here. I had V-Moda Vibe Duo headphones for about a year now, and I am going on to my fourth replacement because each pair was defective (no sound in 1 earphone). I am getting my replacement, and I complained to the Apple Store, and they will allow me to exchange them, because the package is closed. So are there any recommendations on the most reliable/best sound quality earphones? I use them all the time (I live in NYC, so blocking out sound is a great benefit), whether it being exercising or just walking to class. I was looking at the Shure SE102MPA ( http://store.apple.com/us/product/TT027ZM/A?fnode=MTY1NDA1MA&mco=MjQzMzQ1MQ ) or the Sennheiser MM50 iP (http://store.apple.com/us/product/TR530VC/A?fnode=MTY1NDA1MA&mco=MjM2OTAwMQ ). I was looking to see if Bose has any earphones, but all they have are large headphones. Thanks for the help.
