Cardo JBL Audio Set
JBL has been delivering premium sound to audiophiles for decades. Cardo partnered with JBL to create the best sound possible from a set of Bluetooth speakers. These 45mm speakers taper to a 42mm diameter at their base so they can fit in most helmets. This speaker set is compatible with the entire Cardo lineup as well as any other communicator that uses a standard 3.5mm audio jack. Cardo Packtalk, Smartpack, SMARTH and Freecom series owners can upgrade their firmware to attain an audio profile that's optimized for this unique speaker set. Firmware updates are available through Cardo's site.
