Special mount 304 for SENA SMH10 Bluetooth headset for special helmets. The 304 mount does not include speakers, but comes with a flexible gooseneck microphone and a cable microphone that can be positioned freely. The SMH10 mount SMH-A0304 is optional and not included in the set. Purchasing a new or second SMH-A0304 mount is advisable if the original mount is damaged (for example, if the helmet has fallen and landed on the mount) or if you want to equip a second additional helmet. With multiple helmets that have a mount installed, the Bluetooth unit can be easily and conveniently switched. The Bluetooth unit can simply be attached to the desired helmet. This mount is primarily suitable for helmets with open ears (e.g., braincaps). It is delivered with a individually positionable gooseneck microphone and a cable microphone. Speakers are not included. For use, additional earphones or other speakers are required, which can be connected to the mount via a standard 3.5 mm jack. This mount is exclusively for the SENA SMH10!.
