The brushed aluminum finish really remember Apple products. The clean and simple design won me over from the first touch. The arch of the setting is a little tricky (you have to go gently, gently what :)) but once set, it stops moving, which is a good point. The fact that it is foldable and comes with a storage bag is also very practical.
As for the sound, it is certainly less powerful than other competing brands, but through proper insulation and excellent clarity, I will say that this helmet is just nearly perfect.
Amazon delivery was made on time, what more?
NEGATIVE:
After 7 months of current and reasonable use, the helmet failed me. The two screws holding the left atrium were unscrewed at progressively, but at the time I realize it, they had already disappeared. And given their size, can not hope to find them repair the helmet ...
Ultimately, the strength of the construction of this helmet is relatively more questionable than the sound quality it offers.
The good side is that Amazon has agreed that I return the defective helmet and paid me back the purchase price.
CONCLUSION:
I think if you have to spend so much on a helmet, do not buy the KEF M500.
