In summary: a headset, which is probably unique in its price range. The heights come clear and clean, the centers are genuine, bass is impressive without drone. Each at its own listening preferences can carefully engage with a equalizer in the sound. But the headphones already sounds so harmonious that I have turned off the equalizer in this handset by default. The workmanship is good and makes a solid impression. The fit in the ear is perfect and can be adapted by the various sizes supplied with security at each ear size. The headset does not press even after prolonged wear. I am very satisfied.
