Interesting about the rules in France.
I always wore earplugs whilst riding a bike, noise fatigue is a real issue and noise levels in a full face helmet can be very high.
I wear hearing aids which have a significant noise cancelling option, would they be allowed in France?
They also bluetooth to my phone, so I can listen to music or answer the phone. Would they be legal?
I too have bluetooth hearing aids linked to my phone which is great for the navigation app. How would they know if you were using your hearing aids with the phone?
