With regard to the helmet:
The pros:
- The price (although 30 it's not nothing).
- The sound is very good.
- Highly effective insulation.
- Foldable in 2 carrying positions: flat or compact.
- Its weight: 90g (light)
- Comfortable
- 3.5mm jack
The -:
- I had not noticed that it was a helmet with a cable to each ear (but that it was me who did not read carefully enough the product description).
- Due to the fact that it is highly insulating, it is not recommended for use in a discussion or to make music together.
- The framework seems very fragile, to see over time.
- The setting of the arch tends to pinch the hair when the rule.
- Very unpleasant (it hurts) to wear around the neck, due to the lack of padding.
- It captures all cable friction, it can be annoying.
I recommend this product if, in the light of these remarks, it still interests you!
