I'd like to preface this by saying that i already have the HiFiMAN HE 400's. I need a pair of headphones that I can take outside with some good isolation. However, I don't want to lose much audio quality by going portable. I have a FiiO E17 for portable use, so amping shouldn't be a problem. This post is mainly for me to know what to expect with the Mad Dogs w/ Alpha Pads in comparison to my HiFiMAN HE 400's. More specifically, I'd like to know about: treble, mids, bass, soundstage, imaging, impact, and comfort. Isolation would also be nice, but it wouldn't be much of a comparison to the HiFiMAN's.
Thanks very much all,
