I bought my ipod nano in february of this year (2006). Lately I have been having trouble with my right ear. It always seems to end up blocked, I stopped using my ipod for a time and it eventually cleared up, I then started using my ipod again after this and now my right ear has blocked up again. It doesn’t clear for a few days and when I touch it, it hurts.
I do not think there has been any research done to prove this, but I really do believe that mp3 players are making us go deaf. We will be a generation full of hearing problems because of the mp3’s and mobile phones.
Maybe it’s not the actual listening to music, maybe its more the headphones. The headphones that ship with ipods for example are the type of headphones that are being inserted into the ear as opposed to more comfortable headphones that just site on the ear. Maybe it would be worth investing in some headphones that do not go anywhere near my ear canal.
Or maybe it is the volume I listen to my music at, compared to my friend who listens to her ipod at full blast I play mine at whisper level.
