Briefly listened to the Yenona last night. Compared to the HAS30: Less sub bass, maybe slightly more impact Mids recessed but ok Treble is a bit more sharp Overall, less clarity, less detailed, less wide, less open sounding. The HAS-30 the sounds seems to float in an open space with a dark background. Couple notes, the HAS-30 has Sheepskin Round Brainwavz pads and a VModa cable. The Yenona has stock pads but stock cable broke so I'm using a 6.3 to 3.5 adapter with a 3.5 Anker cable.
