In search of real, audiophile headphones, Abyss is already known to everyone. With the Diana, there is now a slightly slimmer headphone that sounds very close to the big reference headphone, the AB 1266 Phi. The Diana is also a magnetostatic headphone and now has a lower impedance of 32 Ohms due to the Phi update. The efficiency remains at 91 dB, and the headphone is now also excellent for use with mobile devices. The fit is still incredibly comfortable, as if it were floating in front of the ears.floating and sonically it even plays a bit livelier than its predecessor. An audiophile reference headphone for on the go.
