In summary, Same Sky's electret condenser microphones are used in a broad range of applications and are available in omnidirectional, unidirectional, and noise canceling polarity patterns. Omnidirectional microphones are sensitive to sounds from any angle which makes them prone to picking up background noises. For more directional applications the unidirectional microphones are more desirable as they receive signals primarily from one direction. In noisy environments the noise canceling microphone gives the best results, eliminating undesirable sounds with a two port design. With numerous other options and specifications, Same Sky is sure to have the ideal microphone for the customers audio application needs.
