Pros:
- Excellent sound.
- Good active and passive acoustic insulation.
- Also works properly without active-attenuation (volume one can put stronger at source)
- Comfortable
Cons:
- The command works only for stop / start and answer / end. The double-click does not work very well. I tried several android software, but nothing to do. Unable to move it from one track to another or change the volume.
- In the subway there are acute screeching. They are mitigated by the good insulation of the helmet but not actively.
