HD 660 S : Outstanding Quality All Round

As a birthday gift for myself, I puchased these alongside a Focusrite Scarlett Solo and an AT2035. While certainly on the more expensive side, I went with these because of their relatively low impedance level (the Solo can only power phones up to 200 Ohms).

I would have to get incredibly nit-picky to find faults with the 660 S. The build is solid as a rock; they rest comfortably on my head for hours, which is helped by their open design; the presence and the space of the sound when listening to proper music or watching Blu-rays is incredible.

Certainly, matter of comforts and the type of sound you want are subjective. But these headphones are undeniably well-crafted. The only 'con' I suppose I could provide would be the price. However, you definitely get what you pay for here.
