Cardioid Condenser Microphone

Scarcely larger than a standard mic clip, the K-Micro is a mini-condenser microphone.

It made news when introduced for $0.99 apiece. The product has been improved to handle louder sources (rated at 145dB SPL) and the price has been adjusted to approximately $13 when purchased in pairs, or $11.50 when purchased in the 7-piece “drum pack.”

Karma K-MicroNote that, despite being advertised as a cardioid microphone, the absence of any venting to the rear of the capsule suggests that these mics have an omnidirectional pickup pattern.

The K-Micro is currently available in two packages:

  • In a “blister pack” of two mics, for $26.
  • In the 7-piece “Silver Bullet Drum Pack” for $80. This includes 7 mics, 7 clips, and a slim flightcase.

Sound On Sound - 2011
Despite their small size and laughably low cost, the Silver Bullets are more than capable of delivering solid results in the home studio. A pair of these mics may not be matched quite as well as more sophisticated models, but although some aspects of the spec could be better, the results are surprisingly good

The Karma Audio K-Micro is also known as: Micro, Silver Bullet.
