Really pleased with this purchase. Went to the Preston shop, had the hat fitted properly as I wear glasses to ride, and everything has to go together. Got them to fit the electronic kit. Sadly the Schuberth system doesn't pair with the DJI as it does with GoPro, but I've attached the magnetic fastener inside the helmet with a Bostik Glu Dot, as shown in the photo, and the DJI mic sits on that, so that I have voice control over the Osmo Action 5. Big thanks to the guys at Preston for being so helpful
