they will definitely get damage overtime when the volume is at max.. most damage comes with a hissing sound or a distortion i think it was damage since the quality of your sound became less..
i don't use any AV and AS at all, you can only get that through adult sites and unfamiliar sites.. Format is a pain so i have a ghost back-up in case..
better yet if you're not into any particular specifications you just can tell us a case style you want, games you played, software you're gonna use. so spec rig team can help you out.
