Product Description
Additional Information
  • Product Description

    The Blue Microphones B4 is a perspex sphere pressure omni small diaphragm. The big omni.

    Sonic Character

    Sweet highs and robust lows with a unique design and sound perfect for ambient recording.

    Suggested Applications

    Captures the atmosphere of orchestral sounds, classical instrumentation, background vocals, organ, accordion, distant miking of any source, particularly bowed strings, and drums.


    Based on the most sought-after omni tube mics, B4 delivers a very smooth sonic character with a slight boost in the bottom end around 80Hz. But unlike its predecessors that were inaccurate when miked in stereo, each B4 is sonically matched together.

    The Bottle Cap Series offers an unprecedented creative palette for Bottle and Bottle Rocket Stage One mics. Inspired by the most coveted mics in recording history and forged for modern applications, the Bottle Caps embrace the past to define the future. The series delivers an extraordinary variety of timbres and polar patterns—with options ranging from vintage to modern—forming a world-class collection that would cost tens of thousands of dollars to obtain with individual mics. With the Bottle Caps, you can capture the unique character, dimension, and nuances of timeless performances from any vocalist or instrument.
