Certainly, it is not totally cut off from my outside, especially if you listen to soft music or low volume, but the attenuation is still quite perceptible.
The sound reproduction is perfect for me, even if it is a little less satisfactory than an open helmet.
The headset is provided with an extension cord and adapter 6.3 mm, which is a nice touch.
Small details:
- Ears warm and tend to sweat after some time of use (especially in summer).
- The helmet does not bend.
- The colors on the screen are very different from reality (more supported and more saturated).
Conclusion: excellent quality / price for a headset perfectly meets my expectations, the Amazon service bonus!
