Give your ride a whole new sound with an easier, safer alternative:
AudioPLUX™ speakers are an "away from the ear" speaker system that delivers good quality audio near the ear while not suppressing ambient sounds around you.
This video depicts Lou Tortola, inventor of the AudioPLUX™, on a Sunday ride with his speakers on. Note the position of the speakers in relation to the ear for an optimal sound experience. Affixed to the sunglasses rather than a higher helmet may work best.
