Multi-mode intercom
The 60S combines Wave Intercom, Mesh Intercom 3.0, and Bluetooth Intercom in one unit, so it covers different riding situations instead of locking you into a single communication style.
That matters because a rider who splits time between one passenger, a small group, and broader riding circles gets more flexibility from one purchase. The practical trade-off is that the feature set is more than many casual riders need, which makes the price easier to absorb only if those modes will actually be used.
