FAQs

Bidirectional microphones pick up sound from the front and back while rejecting noise from the sides. They are widely used in headworn microphones, pilot headsets, and face-to-face communication devices.

Unlike omnidirectional microphones that capture sound from all directions, and unidirectional microphones that focus on the front, bidirectional microphones have a figure-8 pattern that isolates side noise while capturing sound from both the front and back.

We offer a range of sizes, with common options like 9.7 × 5.0mm. All models are designed to fit headset structures or compact housings and can be tailored to your required acoustic and mechanical specifications.
