We tried the JH-5Ms with three full-face helmets—an Arai RX-Q, a Shoei QWEST and a Schuberth C3—on both faired and unfaired motorcycles. At moderate volume levels, sound was excellent up to 50-60 mph, depending on the coverage offered by the bike. At higher velocities, wind noise leaked past, overpowering the music; forget listening to a podcast while lapping the Nürburgring. Regardless of the brand or type of helmet, use caution when donning or doffing your lid. Yanking on the cables is a good way to turn the monitors into an expensive pair of earplugs.
