“How did the HD6 do? Really well, almost surprisingly so. The first aspect of the HD6 that was immediately apparent is that as I mentioned above, they image well. The musical picture they present to your ears and brain is quite coherent, giving you at true sense of the album’s mix (or in Darkthrone‘s case lack thereof). Transients were also excellent too out of the box, since I found the overall experience to be highly energetic – Fenriz really sounds like he banging away smack dab in the center of my living room. Horns up! One aspect of the HD6 I found surprising is that they sounded very good at low volumes, eeking out just enough sonic nuisance to make my ears continue to perk up from time to time. The HD6 is a fantastic product.” —— metal-fi.com
