I live near Succasunna, NJ, about 30 mi from NYC, but close enuf so that most NYC radio stations are full quieting. My NAVA helmet has enuf clearance from earpiece to ear, so that I can just and I mean just, snake the Sony headfones upside down in the right place. Sound quality? OK, but the Sony doesn't have enuf oomph (ie, watts) to drive enuf loudness to overcome a Kawasaki 750 twin at 5000 rpm (about 65 mph) on Rt 80... you can still hear it, but not all that well. However, at 4000 rpm and below (ie, 50 mph and down 5th gear), there are no problems at all, and I really enjoy riding along with music, but knowing that I am not blasting everyone in a three mile radius totally away, as the fairing radios tend to do... As far as permanent mounting is concerned, I would be careful about doing anything to the helmet, to avoid damaging structural integrity. For example, just drilling a mounting hole to mount the earpiece would totally change the stress behaviour of the helmet... Road sounds have never been a problem - I still hear horns, sirens and the like, mainly because the Sony doesn't have enuf power to totally drown anything out, and the headfones are, as you know, very open air... Has anybody else done this???? Mike Sajor, BTL Whippany NJ 201-386-4409 zeppo!mes PS - legality? who knows? I assume that this is ok, but only my local magistrate knows for sure (maybe)...Does anyone know definitively?
