Bosch manufactures a broad range of professional microphones designed for public address (PA), paging, voice evacuation, and commercial audio systems.

A primary category is tabletop paging microphones, such as the LBB1950/10. These are typically unidirectional condenser microphones with a flexible gooseneck stem and stable base. They are ideal for offices, schools, and retail environments, offering clear speech reproduction. Common features include phantom power from the amplifier, a press-to-talk (PTT) button with priority control, and LED status indicators. Their directional design helps reduce background noise and improve intelligibility.

Another key group is call station microphones, including the PLE-1CS, PLE-2CS, and PLN-6CS, designed specifically to integrate with Bosch Plena mixing amplifiers. These expand functionality by allowing zone selection and system control, enabling announcements to specific areas or entire facilities. They are widely used in larger venues like leisure centres, airports and warehouses.

Bosch also offers handheld and gooseneck microphones for portable or lectern use, suitable for conferencing and presentations.

Bosch places strong emphasis on durability, ease of use and system integration. Common technologies include balanced audio outputs for noise immunity, monitored microphone lines for fault detection, and compatibility with EN 54 voice alarm standards. Overall, Bosch microphones are engineered to deliver clear, intelligible speech and dependable performance in professional and life safety audio applications.
