Bi-directional ribbon microphone provides premier, symmetrical audio with off-axis rejection and consists of a shock mount and a case. It features increased durability and a dual-sided transformer to minimize signal loss and stop RF interference.

Main Features

  • Bi-directional polar pattern delivers premier, completely symmetrical audio with superior off-axis rejection
  • Revolutionary Roswellite™ proprietary ribbon material replaces traditional foil ribbons with high tensile strength, toughness and shape memory that provides superior resilience at extreme SPLs
  • Custom ribbon motor assembly tailors bass response without attenuating the overall output for full low and mid ranges, and superior upper range presence from a rising frequency response
  • Double-shielded matched full-sized transformer minimizes signal loss and maximizes output while reducing magnetic and RF interference from 90 degree placement, offset relative to the ribbon
  • 146 dB SPL across 30 – 15,000 Hz frequency response ideal for capturing fast transients in vocals, acoustic instruments and concert halls
  • Legendary Shure quality and superior construction from hand-assembly of machined steel, silver, gold and aluminum materials, and housed in a pure stainless steel casing
  • Spring-loaded suspension shock mount for flexible, fully-isolated stand mounting
  • Upright protective wood case included for storage when not in use


What is the KSM353/ED best suited to?

The KSM353 is best suited to intimate vocal applications.

How is the KSM353/ED different to other ribbon microphones?

Ribbon microphones are renowned for being extremely delicate. The KSM353’s high-tensile strength, toughness and shape memory of Roswellite™ ribbon material replaces traditional foil ribbons for superior resilience at extreme SPLs and allows the microphone to be more durable.

The KSM313/ED and KSM353/NE microphones are both hand assembled in the USA from state-of-the art transducers, transformers and metals
