If Oakley’s MP3 glasses are a bit too expensive for you, you can always get the KS003. They support MP3 and WMA, have 256MB of storage capacity and cost less than 100 EUR. the protection against sun rays is probably not as good as on the Oakleys, but in case you go treehugging during your next skiing adventure, you’d rather break one of these 100 EUR glasses that the Oakleys. The Evergreens are UV400 in any case.
