I'm still writing up my Alpha Dog impressions.
My Intended Use:
From the portable rig, which was what I was originally intending to use the Alpha Dog for, the sound was not too bad. Of course it does not sound as good as the desktop rig (see Objective 2 vs C5 comparisons), but it's still quite passable in terms of sound quality. Now I'm not saying this is a really portable headphone to bring along with you. The cables are thick, non-pliable, hard to manage (the Y-split of the cable reaches my navel), and have lots of cable microphonics (I think the connection from the cable to the earcup wiggles, so you hear all the noise from there); you can see the sides of the earcup when you turn your eyes to the side; the 3.5 mm adaptor sticks out like a sore thumb (unless you use an extended adaptor); and the whole rig is just big and heavy with signs of it being anything but portable. If you consider this a portable headphone, then you're crazy. On the other hand, these headphones are really, really comfortable to wear! Despite its large mass, the earcups have just enough clamping force to stay on my head comfortably and they is plenty of room for my ears.
Sadly they don't sound that outstanding from a desktop rig. They are hard to flaw but not that special IMO.
I wear DT150 outside, the Alpha Dog is actually lighter and easier to wear outside than SRH840 too... Yes, I am crazy. x3
