This is the mount for a Sena DWO-1 Motorcycle helmet bluetooth comms unit and the partial-face helmet mic. It may or may not work for other Sena products. If you've got a DWO-1 and have a different helmet you want to wire up or something, you're welcome to these for free. Wind guard for the mic is a bit torn, but that's easily replaced or it may be fine depending on the helmet. This is *not* a generic headset microphone, this is specific to the Sena DWO-1 motorcycle helmet bluetooth system.
