The Cardo 40mm JBL Speakers are built for riders who want stronger, clearer sound at speed. Tuned by JBL, these speakers deliver rich, dynamic audio that keeps music, GPS directions, and intercom conversations sharp and easy to hear, even in demanding riding conditions. Designed as a direct replacement or upgrade for Cardo communication systems, these 40mm speakers strike the right balance between performance and fit, sliding easily into most helmet speaker pockets. Proper placement near ear level enhances volume and bass response, giving you a more immersive listening experience. With a universal 3.5mm jack, they’re also compatible with most communicator brands, making them a simple and effective upgrade for almost any setup.
