Here's a good way to encourage use in your rig. Remove all of the speakers from your stereo system, connect jacks for each seat, and get one of the Azonic helmets for each. No helmet, no tunes!! And, no, you would not HAVE to wear the helmet (unless you like music).
I'm just going to put my Sub woofer on my head. Looks good, very fasionable, Excellent protection, and the sound quality is superb.
I agree BigMike. It should be a
Choice!
