   Good point. Since it's compulsory to wear a helmet on a bike here (both   
   pedal and motor) wearing earbuds within your helmet is fairly common.   
   Whether it's a good idea on the road is another matter, but I doubt it's any   
   worse than having the same music SPL at your ears, just because it's coming   
   from speakers. If the level is high enough it will mask most external sounds   
   in any case. Something easily possible with most cars if you have both the   
   stereo and windows up.

   It is here, but it may be hard for him to reach that limit with anything he   
   can carry on a bike (as he mentioned) Possible on a motorbike however, and   
   with a car it's not at all difficult.
