I have the 5pin DIN to 3.5 adapter from Wingstuff because I only needed a short line. It works great with both the corded line to my Helmet (Half Helmet with speakers) or my Blue Tooth (through a Sena unit to my Full Face). Both get run through that adapter depending on what Helmet I plan to use that day.
