The GDM HyperSonic is a Bluetooth headset that mounts to a motorcycle helmet for music, calls and rider-to-rider intercom. It is wireless and marketed as a smart unit, in black only. At $79.95 at RideGDM as of November 3, 2026, it is the only new price listed, so it sits at the low end of what helmet intercoms typically cost. That price is worth checking against the brand's own history before you buy, since a single store listing gives no range to compare.
