We are looking forward reading your comparaison between HE1000 and HEX.
I also have a HE1000 that I also love. Could you tell us what headphone Amp are you using (or you prefer) with your HE1000 ?
Well they arrived today and the build quality is excellent and they are lighter than the HE1000s and very comfortable. Out of my iPhone 6, they are excellent. Tonight I'm using my AK240SS with them and there is plenty of headroom...so yes, they are quite a bit more efficient too. Sound so far is similar to the HE1000s as you can tell the family resemblances. More to come....(especially on me review
My Hugo TT is excellent with the HE1000s, but when paired with the GS-X MK2, the HE1000s truly shine!
