MX153 Earset Microphone

The Shure Microflex® MX153 is a professional subminiature earset headworn microphone for use in speech and other applications requiring low profile, discreet placement where improved gain-before-feedback over lavalier microphones is desired.

Best suited to: Speech

Condenser Omnidirectional

The Shure Microflex® MX153 is a professional subminiature earset microphone ideal for speech and other applications requiring low-profile discreet placement where improved gain before feedback over lavalier microphones is desired. Delivering exceptional speech clarity, the MX153 is ideal for corporate presentations, houses of worship, A/V conferencing and live sound reinforcement. Additionally, Commshield® Technology offers superior RF immunity from cellular devices and digital bodypack transmitters. Available in three color options and direct TA4F connectivity to Shure bodypacks, the MX153 provides outstanding clarity in an extremely comfortable, over the ear design.

Features
  • Subminiature, omnidirectional cartridge offers superior speech clarity and enhanced plosive protection with no proximity effect
  • Terminated with TQG/TA4F connector for direct connectivity to Shure wireless bodypack transmitters
  • Ultra-Lightweight, Comfortable, Flexible design is stable and easy to place over either ear
  • CommShield® Technology guards against interference from Cellular RF devices and digital bodypack transmitters
  • Kevlar® Reinforced, Soft Flex Cable
  • Matte Black, Tan, and Cocoa color options available
  • Includes protective storage pouch, 3 windscreens, and collar clip

Remarks:

MX153 performs optimally with 1-5V DC bias. Some bodypacks (like AXT100) may output more than 5V DC resulting in poor audio quality. Please check the bodypack data sheet if this problem occurs on MX153.
