I did a search and didn’t find much. Google hasn’t been much help either - all I seem to find is stuff from Sena (which is way more than I need, I don’t need comms or anything just in helmet speakers). The only thing I really found was some cheaply made looking stuff designed for snowboarding helmets. There’s gotta be more out there. What’s everyone using?
I use a Senna, but only for Siri to allow me to send voice texts, Siri reads the text for me, and make and answer phone calls- via Siri- And, for the voice operated directions on GPS. All the time while riding! It's awesome! I don't listen to music when I ride. YMMV
No help from the old dinosaur here. But... I like the sound of the wind around my Bell. Don't do intercom or music or such.
There is a simple one available - I can’t remember offhand what it is but I’m headed to the shop in a minute, I’ll inspect my helmet and report back.
No information on the unit looks like it will be Tuesday when I get back to work before I can tell you what brand.
