Are the Philips Sonicare S2 Sensitive brush heads compatible with all Sonicare toothbrush handles?

They are compatible with all Philips Sonicare click-on electric toothbrushes, but they are not compatible with Philips One and e-series handles.

How often should I replace the Philips Sonicare S2 Sensitive brush head, and how will I know when it is time?

Philips recommends replacing the brush head every 3 months. With BrushSync-compatible handles, the light on the handle turns on when it is time to replace the brush head, and the blue bristles also turn white as a visual reminder.
