I wondered this for a long time, do having a good sound isolation headphone protects our ears? Cause technically, it'll prevent us from adjusting the volume knob to a higher level right?
So I'm guessing the general rule of thumb is
1. set your volume level where you can hear your music + slightly ambience sound
2. set a volume limit (for iPod users) by adjusting the volume till you can't hear any ambience sound or people can hear what you're listening to
3. prevent listening to your audio device continuously over a long period of time
Correct me if I'm wrong, I enjoy listening to music details but I don't want to spoil my ears at the same time
Oh and volume level is a personal thing right?
