I know there is all this talk about that huigh levels of listening to music on MP3 players can damage your hearing.
But at what level is considered dangerous? I have a Creative Zen 20GB. Most of the time at night in bed, I have it on 1 or 2, but during the day with two pcs running - mine & GF's - i have to have it at around 5 or 6. But some tracks which are reasonably quite it has to go to around 9. The max is 25 on the player. Does anyone know at what level is the safety zone?

Hmmm.. I would guess than any level that does not hurt when listening would be a safe level. I have an iPod nano so I'm not familiar with your Creative Zen sound level but I usually have my volume all the way up, but not quite at maximum.

If you feel comfortable when the music is playing then I guess it's at a safe volume.
