how mics are made. Watch the video.

Meet the Dualdyne

Achieving the sound quality demanded by elite performers and venues no longer requires sacrificing the rugged reliability of a dynamic microphone.

The KSM8 Dualdyne features a patented cartridge design with two ultra-thin diaphragms and groundbreaking reverse airflow technology.

Here are a few more of the technological advancements that make the KSM8 Dualdyne a game-changer in live sound:

  • Unmatched control of proximity effect means a huge sweet spot
  • Accurate, flat frequency response greatly minimizes the need for EQ and processing
  • Truest cardioid polar pattern available controls bleed for a more natural sound

77 Years in the Making

The KSM8 Dualdyne. A dynamic microphone revolution that only Shure could stage.


Shure develops Unidyne® cartridge technology, which rejects sound from the rear of the microphone to reduce signal feedback.


Shure advances dynamic cartridge technology with the Unidyne III cartridge in the SM58®, featuring the pneumatic shock mount, which drastically reduces handling noise.


Shure Dualdyne™ cartridge technology provides unmatched sonic accuracy in a dynamic cartridge while all but eliminating proximity effect.

How it Works

Dent-resistant, hardened carbon-steel grille

Lined with hydrophobic woven fabric for exceptional protection against wind, plosives and water, the KSM8 Dualdyne grille is durability redefined.

Patent-pending Diaphragm Stabilization System

Protecting and stabilizing the active diaphragm during plosives and impact, the DSS greatly reduces high-frequency handling noise.

Patented cartridge design with two ultra-thin diaphragms and reverse airflow

Controlled proximity effect vastly increases the working distance without on-axis coloration, delivering the most accurate frequency response available in a dynamic microphone.

Reimagined Shure pumping pneumatic shock mount

An elaborate architecture of tuned cavities, specific resistances, and precisely machined components is fully integrated into the cartridge’s acoustic properties, dramatically reducing handling noise without loss of low-end response.

Acclaim for the Dualdyne

The KSM8 is a very full-throated mic. It captures all the warmth and depth of Jennifer's vocal without losing the crispness of a lightly sung lyric, all the while maintaining its composure as she struts in front of the PA. The only feedback I’ve had isn’t from the mic – it’s from people talking about the mic!

Gordon Mack FOH Engineer for Jennifer Lopez

The first thing I noticed about the KSM8 was how nice it looked; however, its good looks were very soon eclipsed by how great it sounded. The highs sounded silky and transparent with an equally impressive and very tight low-end response. Proximity effect is greatly reduced, leading me to bypass my compressor for the entire show. This is an excellent microphone and will be my first choice in vocal mic selection going forward.

Al’s mic technique is as varied as his vocal stylings, which range from beatboxing and vocal percussion to quiet whispers. The KSM8 excels across the board at both FOH and monitors, which is rare. This mic makes mixing the band’s IEMs, monitors, and FOH much easier. It brings high-end clarity naturally, without the need for additional processing and EQ.

The KSM8 is stellar. I can say unequivocally that the KSM8 surpasses every other dynamic vocal mic I’ve tried. The polar pattern, proximity control, and flat top-end response give this mic a very wide and deep sweet spot that’s perfect for corporate events.

Harold Blumberg Event Sound Designer

The off-axis rejection is amazing. Low-frequency response is very smooth, and high-frequency response is noticeably enhanced. I definitely noticed nice proximity control, too. It’s an exceptionally well-designed microphone by Shure.

Michael Abbott Broadcast Mixer
The Voice, Shark Tank

The KSM8 is a phenomenal mic for IEMs. It’s the only mic I can use with in-ears that sounds natural in the low end. It’s crazy how little processing and EQ it needs. The off-axis bleed is so clean that it immediately cleared up my in-ear mix.

Jason Batuyong Monitor Engineer
iHeartRadio Stage

The KSM8 capsule is a life-changer in monitor world, especially for in-ears. When Jennifer is moving between the PA, side fills, and the live band, and the audience starts screaming, the KSM8 gives me the clarity and control I need so that her vocal easily cuts through it all without bleeding.

Anne-Lise Coulet Monitor Engineer for Jennifer Lopez

Warm and natural! I barely used any EQ or processing, which is every engineer’s dream! I think you have a real winner here. The KSM8’s versatility sets it apart.

J. Mark King Music/Production Mixer
Dancing with the Stars, Country Music Awards

I used the wireless KSM8 for a corporate gig, and I love the off-axis response! The CEO got far away and off axis with minimal audible change. It was stable even in a very odd PA design. The working distance is huge on this mic and made my job so much easier!
