Excellent microphone, great price

By Kenneth G.

I have been looking for a directional lav to help with room noise problems for TV recording. This works great.

Audio-Technica AT831B Cardioid Condenser Lavalier Microphone - SKU#1954682 Features

  • Miniature Capsule: The miniature, unobtrusive capsule allows for easy concealment underneath clothing
  • Cardioid Polar Pattern: The cardioid polar pattern is effective in minimizing audio signal at the off-axis sections of the capsule. This provides high gain-before-feedback response while using nearby monitors and speakers
  • High Sensitivity: The frequency and sensitivity response of the AT831 result in transparent, pristine audio signal reproduction with low noise floor
