Pros
Pro Bass and treble are emphasized
These headphones have what is called a V-shaped sound signature where the bass and treble are boosted while the mids take a backseat. The bass is powerful, deep and satisfying. In-game explosions will sound powerful and have a lot of rumble. The boosted treble makes audio detail up front, so nuances in the audio can be clearly heard.
Pro Not tiring to wear
The HD681 will not put a lot of strain to your neck and head, even for long periods. Coming in at around 220 g, they are relatively light. This is due to the use of plastic as the primary build material, along with small metal tubes on the headband frame instead of large plastic or metal parts.
Cons
Con Thin ear pads may cause comfort issues
The ear pads are made of cheap feeling synthetic leather which can get warm rather quickly. To potentially add more discomfort, the cushioning inside these ear pads is quite thin, and can hurt the area around your ears when worn for many hours straight.
