Its done guys, H1 ordered!
As soon as I get them (week or 2) I will give my impressions compared to the XBA3 and re400.
Pretty sure the headphone jack on the PC is altering my sound... How common is this, and would a Fiio E6 be a good buy to remedy it? Nevermind that the E6 is a great buy regardless... Now I'm beginning to feel it: <good gear ---> upgradeitis>
Sound output through digital such as HDMI is more neutral...
Long time lurker, first time poster, I picked the H1's today and after an afternoon listening to them I would say compared to the xba-3's they have a much better soundstage ,better (slightly north of neutral but not by too much) bass and more natural highs, but don't have the detail or separation that the xba-3's have. Overall I would say they're a solid side-grade and well worth the money, but not necessarily a definite upgrade.
Examples of songs where better separation shines:
Note that this is nitpicking and I'm still very heavily considering replacing the xba-3's with the H1's as my walking around 'phones.
Edit: should probs mention that all listening has so far been performed form my phone (HTC One V) which is not a particularly good source.
I would say the H1's are a slight downgrade in technical ability but superior in sound signature lol, it's a bit of a dilemma for me now which to keep as my everyday 'phones =S. I guess it depends on what aspects of sound your priorities lie in.
