Was very curious about this because I was talking to my doctor who owns a nice speaker system. I told him I was into headphones (cause I'm not a doctor :D) and he told me that those things are really bad for your hearing.
Now, he is a doctor but he could still be pretty much talking out of his ass on that one. Is there actually a difference whether you are listening to music over speakers, headphones or IEMs? IEMs concern me the most since they seem to be injecting the noise right in there so if any of these are bad for your hearing, I would assume IEMs. Obviously I know that listening to anything really loud is bad for your hearing but will the same volume on headphones and IEMs be more destructive?
He also told me that treble is really bad for you too which concerns me a lot as a Grado user...
Please help me confirm or dismiss these statements!
