Okay, we've hit a wall here and a search didn't show any similar problems.
We have two of the Shoei Multitec helmets, and a couple of the Autocomm type B helmet speaker and microphone setups.
Speakers went in with no problem, but we're stuck on the microphone install. We've tried a number of configurations, and none have been satisfactory.
First, the Multitec is noted for having a microphone hole all cut out in the chin piece, ready for simple insertion of the mike. It seems like a good idea, but when wearing the properly-fitted helmet the hole for the mike is a full inch lower than the mouth. If that weren't bad enough, there is no apparent way to get the mike into the hole without taking apart the helmet or possibly cutting the mike wire and then soldering it back together after insertion. All of which would be do-able, but we'd still end up with an improperly-positioned microphone which wouldn't trigger on the sound of our voice.
Okay, not knowing all of this, we removed the "boom" from the mikes and tried the install by putting tape over the hole and then velcroing the mikes to the tape in the correct position relative to our mouthes. This worked so-so, in that the wiring to the mike had to be taped along its entire path, and the mike would periodically come loose from its velcro mooring.
Now we're at the point of fabricating new booms with some stiff wire and some heat-shrink tubing, and installing the mikes as one would in a 3/4 helmet.. with the boom in front of the mouth. We assume we'll completely ignore the hole the mike is supposed to fit into. This seems a shame, as it would seem like it would be such a nice and clean install if that hole could be used.
I've seen postings by others with Multitecs saying how the hole is in exactly the correct position, and all I can do is scratch my head.
So, before we attack the problem once more, creating new booms and abandoning the idea of using the Shoei mike hole, does anyone have any insights they might share as to where our understanding of all of this is flawed?
BTW, we love the Multitecs, although I'd be interested in a regular full-face Shoei now that I've realized that a geezer can wear contacts. I was stuck with glasses, which is why I went for a flip-up in the first place. But that's all an aside. We own the Multitecs now, and it will be a few years before we'll want to replace them ($$$), so need to solve this problem somehow.
Thanks for listening to my rambling. It's early for me.
