HD-681 Evo WH : Great sound and comfort, but flimsy build and cheap-feeling.

Definitely one of the best headphone (along with other superlux headphones) in its price range and even competes in the sound department with more expensive headphones in the 100 Euro range.

--Sound--

Good bass hump, slightly recessed midrange and good high extension (Slight V-shaped sound signature). With the default pleather pads, the sound is 'closer' the mids are a bit more present. With the included velour pads, they sound a little distant, but the velour pads are much more comfortable.

--Comfort--

Great comfort with the included velour pads, the pleather pads are not very soft, and will make your ear sweat. Clamping pressure is fine on my personal use.

--Build--

The white accents are very glossy, which makes them very cheap looking. But otherwise the headband are good and solid, and slightly padded (compared to the non-padded HD 668). The ear cups are very solid as well.
