You can find a lot of similar data across a pretty wide array of headphones on the market on rtings.com as well. For instance, here's your HP50 headphones: https://www.rtings.com/headphones/reviews/nad/viso-hp50 https://www.rtings.com/headphones/reviews/nad/viso-hp50 I really like some of the non-sound related measurements they perform -- the clamping force and breathability are pretty important for comfort. For instance, as someone with glasses there's a good chance those HP50s would not be remotely comfortable as the high clamping force on the glasses arms tends to get pretty irritating after a while. Their more thorough sound tests are really invaluable as well -- for instance, apparently the bass response goes down considerably with the HP50s when the cups can't form a good seal (e.g., if you're wearing glasses).
