The idea of using ANC while piloting a motorbike makes me cringe.
I can understand that, from many angles. Here’s why I’m going to give it a shot:
1) transparency mode: I have gone shooting with Pro 3’s in. Loud sudden noises are attenuated well, and settings can make the loudest sounds within hearing safe ranges.
2) using a gaiter over the ears AND removable plastic ear clips will drastically reduce the likelihood of an AirPod deciding to bail on me mid-ride. I haven’t had one fall when removing the helmet but I’d park in a dry and clean spot just in case.
3) phone calls seem to work fine with the Pro 3’s stuffed up against the skin / face. No one reports hearing my voice muffled or unintelligible.
Remaining concerns:
crash safety. I’m not sure if slamming my helmet against the ground would cause damage to the ear cartilage. That’s not something I can test really. I can push against my ear and smush the AirPod into it to see if there’s any pain . . . if there is, that would likely be 1000x worse with a major impact.
Battery life and Charging: for longer trips, it would be a PITA to remove the ear clips every time I need to top off the battery, versus running a Cardo and some foamies.
Other Riders: this isn’t a concern right now because I ride solo. But in the future, I may want to get a Mesh-capable comms unit like the Cardo if I’m riding with some friends. I would first try out the Wave Intercom app to see if that does the trick.
Any other concerns are shared with ANY helmet audio system or ear plugs, like not being able to hear horns and sirens as clearly. It’s the contradictory nature of the beast, protecting hearing while keeping situational awareness.
