After owing 120+ pairs of headphones, I despair of such brands, B&W, Focal, Martin Logan and Alpine etc coming into the game. For me such brands are leaping into an ever increasing market of portable audio just when home audio and car audio is in serious decline (as the sale of Pioneer and Dynaudio companies attest).
I'm afraid the likes of Grado, Ultrasone, Sennheiser, AKG, Audio Technica can and do walk over the 'new kids on the block' (Alpine).
I've owned over 35 pairs of Senn's including the HD-25-1's and HD650, down to just over 10 now, and 10 pairs of Ultrasone's, 7 pairs of Grado/Alessandro, and nothing from the likes of Monster, Focal (owned car audio speakers), B&W. There's a reason for that!!!!
