At least the discription on the web site for the HC2 said the right things. I called and talked to the manger. He was cooperative to the point that he wrote in an e-mail that I could buy and test it and if it did not work the way I wanted, I could return it for a full refund. On that basis, I bought one. I connected it to the Switched-Accessory-Power-Outlet that is factory provided. the dongle turned on, and finally paired to my O'neal Azonic SC1 helmet with a Blinc bluetooth. Every thing worked fine in my garage. A few days later, when I took the bike on a road trip, I experienced that, at speeds above 50 MPH, the bluetooth communication from the dongle becomes annoyingly staticy and impractical. Since bluetooth communication from my cellphone was ok at that speed, I knew it was the dongle and not the headset. I spoke with the manager again, and he said the cause is probably the AVC, the Automatic Volume Control, on the bike. we lowered the AVC and tested again. it worked fine. So I went ahead and bought a Scala Rider G4 and found out that it does not work with the AKE dongle at all. Again, the manager at Spoiled Biker agreed to exchange my Scala G4 with a Sena SMH 10 bluetooth headset. Now, I can tell you, the AKE HC2 Dongle paired with the Sena SMH10 headset works just fabulously and I am pleased to have gone the length to get rid of the cord.
I gave the dongle a 4 star rating, because the combination of the dongle with the DIN plug is not convenient. the body of the dongle and the din plug should be one peice. but it works well after all.
