Review on High-Quality Superlux HD 681 Dynamic Semi-Open Headphones - Boost Your Audio Experience by Nguyn Hong Qun  (Qun ᠌

Revainrating 3 out of 5

It's not a bad product, nothing extraordinary.

While the bass may use some work, for the price, the quality is adequate. The quality is poor at first, but improves after 10-20 hours of listening (after you've had a chance to "warm up").

Pros
  • In terms of cost, the sound quality is adequate.
Cons
  • No special effects, just the vile odor of shoddy Chinese construction! When I used headphones with the same design but a "F" index but made a year earlier, I didn't notice any odor.
