Hi !!
i find disturbing the click mechanical noise of many keys on my CASIO PRIVIA piano (particulary when playing fast passages). Service say it is NORMAL noise, and that i have to live with it

, or switch to another piano brand (altough they prevented me that even more expensive ones as YAMAHA or KAWAI make some noise, and that i have to evaluate whether it is worth the change...).
So far, so good...But my point here is not to complain about the keys's noise, but about intensive playing trough headphones.
I find a real pleasure when playing trough them, because i do not hear the annoying CLICKs !!!
But, on the other hand, i am worried about headphones abuse

Let say you play 2 hours a day, allways trough headphones (at a moderate volume, of course). Do you think that ears can be damaged this way?
Or, put it in another way, do you consider that headphones use should be only occasional, because too much is definitively nocive for your auditive system?
Thanks !!!
