Sena 60S coming

[Sidekick]

Could it be background wind and road noise of all of the bikes combined?

I have had complaints about my 1300's engine when my helmet is open.

I mainly ride with other ST and BMW bikers, and we’ve all experienced some form of radio interference at times. It’s not wind noise from open visors but more like a fluctuating hum tied to engine revs. My theory is that Sena units might lack sufficient radio insulation, which makes them prone to interference from the bikes' electronics.
