Well I have had them for a couple of days now and they have received some extensive listening via both my portable rig (ipod & TTVJ Slim) and via my Laptop & Arcam rPac. I'm not really a very good reviewer but here are my initial impressions:
I Like them, in fact I like them a lot. I have found them to be a very enjoyable and easy listen. Bass is good, punchy and not over the top (I did find initially on some tracks the Bass seemed to feel a bit bloated and overpowering via my portable rig, however a couple of changes to the EQ on the Rockbox software and all was fine).
I am finding, to my ears, these are very good with female vocals and have a nice midrange and crispness to the treble. No sign of sibilance at the higher levels. Vocals seem too be well placed against the instruments and have a surprisingly airy sound...especially to say how small they are and the fact they are closed back.
They sound very good straight out of my iPhone and iPod, but do find I get slightly better dynamics when amped either via my TTVJ Slim or from the rPAC if listening via my Laptop.
As mentioned numerous times before by other people, the build quality is exceptional and they feel nice and solid in the hand. I have had these on for upwards of two hours at some points and dont have any issue with the fit of comfort (I'm one of the lucky ones then )
Having listened to these extensively over the last couple of days, I have now decided to actually sell my Grado SR80i, which now sound weak and lifeless. I was contemplating selling these to fund another pair of more upmarket opened back headphones and that decision has now been finalised.
And here is a picture of them with my iPod and TTVJ Slim Portable Amp
