MLE, I had the HE400s for a brief time and my experience was nowhere near as positive as yours. I couldn't put my finger on it exactly, but it seemed like there were sections of the highs that were completely missing. Like the FR dropped off and then spiked back up.
I don't know, I read everywhere how people are loving the HE400s and I really wasn't that impressed. I am starting to think my pair was defective.
Do you notice anything missing or dips in the treble on your HE400s?
Treble's smooth and sparkly as can be for me. Anything more pronounced, especially in the lower treble, could easily be called bright. As it stand the he-400 is already a bit of bright. Are you referring to the 5khz upper midrange? The he-400s are a bit tamed down there-- the area where you typically hear the slap of drums.
A quick way to tell if you have older or newer he-400 is to take the pads off. Black magnetic structure is old, white is new.
I always found the AD700 to have trouble distinguishing front and back when people are in close proximity, but I remember you said that was just a weakness of dolby headphone in general, and takes a while to get used to.
Man with hearing how good the ad700 sounds at positional cues, the a900x must be even better, put I just can't get past their cheap wing headband. If only Audio-Technica would fix the headband, I would probably snap the headphones up in an instant.
Send them an email about it, I did.
