I would estimate that Ive spent at least 2,500 hours wearing these headphones with the original ear cushions. The sliders have detentes, and are actually unnervingly loud when pulled on. Battery life at least is close-ish to the 12 hour mark if used at around 50% volume. I originally purchased a Tile and decided to return it because the separation alarm wouldnt go off for about 10 minutes. I wish I would have discovered this compression garment a week ago, but I am grateful to have found it. The volume drops off quickly when I move it further away but that means its pretty good at isolating my voice from background noise, so is a reasonable compromise. FURTHER UPDATE - Beyerdynamic confirm that the rattling is a fault and not part of the design. It doesn?t form fit well. As for the gaming aspect, I did not purchase it for that feature, so I can not speak to the ability of this mouse in that aspect. I have bigger hands and struggle with most standard mice.
