The right ear in the white headphones that came with my iPod touch isn't working very well, which is quite an annoyance seeing as I listen to music and watch videos every day on my iPod. Do you have any headphone recommendations? I'd like to spend less then $50 but get a nice pair of headphones, maybe In-Ear, that will last a long time and have good sound. I'd also like to buy them from Amazon. Any suggestions? Thanks!
