Ok here is what I did.I use a sony sports Discman that has anti skip.It is velcro'd to my tank but you have to make some sort of a shock absorber for it.I used a 1 inch thick piece of foam and superglued velcro to both sides of it.It sits just behind the steering head at the front of my tank and the discman is velcro'd on top of it. On the headsets you have to make sure you have the speakers that are about the size of your ears ( not the little ones that go in your ears)You have to carefully remove the plastic band between the speakers so they are connected by cord only.With your helmet you will have to take apart the inner liner and fit each speaker inside the liner where your ear sits.You will most likely have to trim some padding and styrofoam out.Next use silicone to hold your speakers in place inside the cheekpiece and fold your liner back around it.Then just tuck excess speaker wire inside your helmet and put the cheek piece back in the helmet. All that should be hanging out is a small portion of the connection part of the cord. I found an extension cord that was compatible with the discman and I use that to connect my helmet to the discman. This sounds complicated but its not.As far as the extension it is the same cord used by chatterbox.This takes about an hour to do and works pretty good. If you need pictures let me know and I'll send some to ya.Hope this helps.
LuyMyF41, I wonder whether all this would compromise the safety aspect of your helmet. Would the ear pieces go into your skull if you hit the pavement hard? Not to discourage you on your music listening pleasure while riding, but you might want to consider this.
aravindgr,You have a valid point.I'm not a ballistics expert but to be honest with you I dont think the speakers would make much of a difference in a wreck. They are secure within the cheekpad.I guess maybe in a highspeed blow to the side of the head they could cause additional injury,but from a few of the motorcycle fatalities that I have seen up close it doesnt make much difference.If you take a hard enough blow to the side of the head; helmet or no helmet its lights out.
