Ive got a demo unit of HE5 today, I will bring this one for our coming Tokyo headphone show.
The build quality is fairly nice, woods looks like solid. The plugs are detachable as seen in the picture.
I was told HE5 needs some burnt in, however HE5 sounded damn good even just out of box.
I first felt expansive spatial feeling and large sound staging. Overall sound is rich and I also felt a beautiful timbre.
Highs and bass are very sharp and quick, this is surely a planar characteristic. Violin and wood bass sounding exceptional. At the same time, this is not sibilant. This must be carefully developed, I was impressed.
I have been a bit occupied by photo trip over this weekend, so here is just a quick inpression and only one picture available.
