Premium Performance for Stage and Studio

Whether you deploy it onstage or in the studio, the Shure KSM137 delivers premium performance. This end-address, small-diaphragm condenser microphone boasts a gold-layered, low-mass Mylar diaphragm for superior transient response along with a transformerless preamplifier for super-transparent audio reproduction. The KSM137’s highly consistent cardioid polar pattern offers exceptional isolation, while a built-in subsonic filter eliminates unwanted low-frequency rumble. A 3-position pad and a 3-position highpass filter round out the KSM137’s impressive feature set. The KSM137 possesses the coveted trifecta of versatility, durability, and precision, making it an excellent choice for live and studio applications alike.

Superior build quality ensures top-shelf sound

Over 90 years of mic-building experience went into the KSM137’s design, and it shows. Its super-thin, 2.5-micrometer, 24-karat gold-layered, low-mass Mylar diaphragm exhibits superior transient response, while its Class A, discrete, transformerless preamplifier yields incredible transparency, lightning-fast transient response, near-zero crossover distortion, and minimal harmonic and intermodulation distortion. Premium electronic components, including gold-plated internal and external connectors, add to the KSM137’s superior build quality.

A secret sonic weapon with pro-level features

The Shure KSM137 is jam-packed with the pro-level features you’d expect from a microphone of this caliber. A built-in subsonic filter eliminates the sub-17Hz low-frequency rumble caused by mechanical vibration. You also get a 3-position pad (0dB, -15dB, and -25dB) for handling high-SPL sources plus a 3-position highpass filter switch for counteracting proximity effect and reducing stand-vibration noise. At Sweetwater, we’ve found the KSM137 to be a top performer — a serious sleeper hit — on acoustic guitars and drum overheads. If you’re looking for a secret sonic weapon, then the KSM137 definitely fits the bill.

What is Certified Open Box Gear?

At Sweetwater, we're so picky that what we call "Certified Open Box" is actually better than what most music retailers sell as "new" gear! Our gear hasn't endured hundreds of people a week plunking away at all the keyboards, fumbling through Stairway to Heaven on every guitar or playing with every fader and knob on a mixer or control surface.

Certified Open Box (also known as a demo) means we’ve had it out of the box for our YouTube channel, displayed at events, tested in our studio, or maybe it was in a customer’s hands for a few days and isn’t ‘factory fresh’ as a result. Every Certified Open Box item we sell has Sweetwater’s 2-year Total Confidence Coverage™ warranty and has been tested and verified up to ‘new’ specs by our factory-authorized technicians to make sure it’s in perfect working order before we ship it to you.

When you buy a Certified Open Box item at Sweetwater, you get:
  • 2-year Total Confidence Coverage Warranty™!
  • Products inspected and tested by our factory-authorized techs, guaranteed to function like new (or better)!
  • FREE shipping on most items
  • Equipment that will MEET or EXCEED your expectations!

Reviews

Excellent little mic
I bought these on the recommendation of a soundtech pro I know. We needed them to mic orchestral instruments for a Christmas program, and then I turned around the next week and used the same mics for our children's choir Christmas musical. The mics worked awesomely in both contexts. no regrets with the purchase, and I plan on purchasing more of the same if we need additional mics in the future.

Shure KSM137
This is an outstanding pair of condensers having replaced my sE Electronics SE8 mics which I used for roughly five years. These Shures have a flatter frequency response, more accurate transients, and the low-end is impressive. The included A27M Mounting bar is perfect for me as I mount these in XY configuration 36" above my snare. A great package!

Great overhead pair!!
These are a great pair for drum overheads; simple yet utilitarian! Built in pad and HPF work like a charm. I'm just a bedroom studio guy, but these will forever be in my mic locker as I move forward in life.
KSM137
Fantastic.
Great Choice
I love my KSM 137's. I've been getting great results using them as overhead mics. I like how flat they are and how versatile they can be. Definitely recommended if you're looking for a matched set of overhead mics for under $1000.
