I really enjoy the sound of the HD6XX. However, when I have the urge for some deep bass, I have to look to my other cans. I typically reach for the Ultrasone HFI-680s, that maintain a neutral response with great bass and sub bass, but their sound is harsh compared to the 6XX.
I guess I could pick up a pair of Sennheiser HD598 Cs or the Beyerdynamic DT 770, but I am curious if Massdrop is considering a closed back version of the HD6XX.
Any thoughts or suggestions?
Based on discussions, I think the Fostex TH-X00 will suit my wants. Unless, of course, there is another Massdrop x Sennheiser collaboration in the works.
