Iwas disappointed after my first day. the rubber tips are so thin and flexible it's hard to get them into your ears. I have an apple classic Ipod and I messed around for a half hour with the bass, loudness, treble, eq functions and I could not get as good of sound as I could with the factory ones that came with the nano pod. I bass sounded like it was maxed out way sooner than the factory ones. I will probably go back to using the factory ones and feel like I wasted $35
