Listening to the HE-400 as of now.
Treble is a bit recessed.
Bass not as loud as i thought it would be, but the extension is way better than any headphones i've ever tried.
Separation and detail is clearly amazing.
Resolution on these are stellar.
Cans are very very very open. When i put them on, it sounds like it only suppresses 5% of sound from that of bare ears. (I can watch/hear tv while having headphones on)
Not very neutral, more of a fun laid back sound (however not too laid back)
Best way to describe it, they sound like Audioengine A5+ speakers made into headphones with less bass.
0 hour burn in by the way, opened the box and immediately connected them to my NuForce Icon HDP w/ Sigma 11 PSU
Will listen for about 10 hours before switching to Velour pads which i have in hand.
I don't know, but by looking at the pleather & velour, i can tell the velour will be better for my ears (in term of sound quality) Looks like it would give better treble due to it being less enclosed. (stitching)
UPDATE: Sounds better than my AKGQ701 & Sennheiser HD650.
It's a little darker, and not as full sounding as the HD650. HE-400 makes me miss less of the HD650's smooth sound signature.
Gives me enough treble but not overflowing treble like the AKG Q701. treble hurts my ears somewhat (fatigue)
