Some will simply sell you parts while others want you to send your helmet for their installation. Often the installation requires cutting away some of the liner which might slightly distract from the safety and comfort of the helmet. Most use adhesive backed speakers though I have heard of one which requires drilling holes in the helmet (which probably reduces safety considerably). These are very special, ultra thin speakers. I suspect Walkman headphone speakers would be too thick for this application. What I use is a special liner/speaker combination make by Nava for use in their helmets only. As the liner is thicker than the regular liner, it is harder to hear street noises even when the thing's turned off. As for legality, that varies from state to state. They're illegal in Illinois (except for the police). ihtnt!niel
