Yeah. Got it, my answer is above. Dunno why am I quotting here.
You can damage headphones with too much power. The break/burn in discussion is seperate too that.
It is related to an unproved or disproved notion that to get the best sound quality from new headphones/speakers or other components, you need to break them in by just playing hours and hours of music through them.
Ok, waco I liked your explanation also. So if you buy a headset/headphones/subwoofers and you put at max just after u bought it lets say for 100 hours. That might break. Yeah. I wouldnt ever go to max volume. Well I did with the iPod but just 1 or 2 seconds just to test max sound but that put me very nervous and anxious and I wanna die (no that last was a joke.. the die part). When I bought my Home Teathre I also wanted to test max volume but that is something that put me very nervous too. I wanted to know what number was the maximun. It was 40. But I didnt tested with sound. I put something with very low sound up to 40. Because 40 is really loud. It is 600w not much but that is ALREADY a lot to me and neighbours will hear it... and I feel like it is going to break something I dont like to play myusic or movies very loud, just a cool decent medium-high sound but no more.
If you don't exceed their limitations there's no difference in life. The first few minutes of play probably shouldn't be at absolute maximum power though. "Loud" play is fine...OMG MAXIMUM VOLUME play right out of the box is probably not what you want to do.
