A studio and stage standard small-diapghram condenser, the Shure SM81's detailed, flat response will give you an accurate sonic picture of acoustic sources and more. This workhorse mic has a switchable low cut and 10 dB pad, and of course, includes a clip, windscreen, and case.

The Shure SM81 has long been a must-have microphone for capturing the unique timbre and characteristics of acoustic instruments.

The Shure SM81 is that microphone. It's also plenty tough enough for the stage, which is why you'll often see a pair of SM81s hanging over a drum kit.

The SM81 is a cardioid condenser with a wide frequency response and low RF susceptibility that makes it perfect for guitars, pianos, cymbals, mandolins and any other acoustic instruments.

About Shure

S.N. Shure began his company's relationship with the products of personal sound by launching a one-man operation in 1925 that sold radio parts kits. Since then, Shure microphones and audio electronics have been the tools of choice for politicians, musicians, corporations, churches, and broadcasters across the world. Anyone who considers sound to be an important part of his or her self-expression has probably used one of Shure's microphones, phonograph needles, or other professional audio products.

"Save your money for the thing"
This review has been selected by our experts as particularly helpful.
I need to purchase two more because I know that someday the two I have had for 20+ years are just going to die. I have played with many other fine microphones, but none are a substitute. it's kinda like your favorite pizza. there's all kinds but you know exactly the one that satisfies you every time.

Sound
If your looking for an absolutely true sounding mic you'll be thrilled with the SM81. It is clean and transparent thanks to its proven rugged construction and Flat 20-20khz capability.

Features
I have used this mic for drum overheads (outstanding imaging). One of the few condensers that I would use on Snare (on top or underneath). It's Low Freq. roll-off switch is very smooth sounding and makes it an extremely versatile mic. If you do Live recordings, just pop two of these babies up in the room (I prefer using a Near-coincident pair technique) and wait till you hear the spacial realism. Also great for acoustic guitars. No self respecting studio should be without a pair of these. They once came in matched sets, but these mics are so consistent that is not necessary. Sure has some outstanding good mics over the year but the SM81 is in my opinion a Hall of Fame mic.

Ease of Use
Even if your technical mic skills are lacking, the SM81 is very simple just point it at what you want to hear. The Unidirectional nature of this mic helps to reject sounds from the side and read more from in back. With that in mind you can use your creativity to either focus what your recording or depending on proximity capture an area of sound. Shure includes very useful specifications and you can find micing tips on-line.

Quality
The SM81 is supremely reliable and the product meets the specifications that accompany the mic. I purchased my first SM81 in 1985 after years of on-the-road and in studio use it is still operational today.

Value
This is a microphone worth saving your money for. The SM81 is a classic great. I other condenser mics that cost more than double the price of the SM81 and in certain applications, it my mic of choice.

Manufacturer Support
I once knew some of the folks at Shure and I can tell you they are passionate about their mics, and their customer's satisfaction. I have not used their customer support channel though.

The Wow Factor
In my opinion the SM81 is one of my favorite condensers for drum, live and acoustic micing period. It reliable and true. How much more sexy could you get when making music.
