SOLD
I have a slightly used HBC100 Plus for sale on ebay if anyone is interested. I have used it a few times but never even took the backing off the velcro pads that hold the speakers in. The boom-less microphone system for the phone works amazingly well even through loads of full face helmet pads. I was surprised about that but since I don't commute and have zero friends interested in using comm systems this has been sitting in a box in my closet. My loss is your gain.
This does work with other brands.
This works for music, phone and communications
Retail is anywhere from $129 to $149.99 + Shipping. My auction starts at $75 plus $5.95 shipping and it's in the original box with all the stuff that came with it.
