hi guys i i own the hd650 and have it connected JDS LAB the element dac/amp and was wondering if anyone had the chance to measure the decibels when its on max volume high gain. even if some of you measured it on a schiit stack or o2/odac i would like to know

I'm looking for a pair of headphones that are designed specifically to prevent hearing-damage and/or hearing-loss while creating and listening to music. Would be nice to find a pair that I can set the headphones to a certain decibel? I prefer over-the-ear but any would do, something affordable...
