Bass killer, lifeless, ess hump shill, in ear knifle like, metallic sound...
Dx3pro+ literally killed all my HP's bass. Even first gen k3, my second hand zxr, k5 pro akm sounds much much better than it.
Tygr 300r, dt770pro, Hd650, even my Denon D5000 (which has subwoofer tonned bass) totally sound dull. Like someone sucked all the bass out.
Low-Fr quantity is significantly less compared to all my other sources but it also hits fast with no decay time. You wont feel anything with these in regards of bass frequencies.
Latest FW, latest drivers, tried all the filters... Same. How can this be praised that much ? Un-believable !
