The SM81 is ruggedly constructed. It operates on phantom power and performs over a wide range of temperatures and humidity conditions. It is furnished with a swivel adapter, attenuator-switch lock, foam windscreen, and case for carrying and storage. Other accessories are available.

What We Think - Shure SM81 Review

"The Shure SM81 is a classic microphone that finds new relevance and necessity in the modern digital recording world. It's smooth response and non-hyped top-end make the SM81 a go-to mic for classic sounding acoustic guitars, drums and percussion recording. Feed the SM81 into a nice preamp, point it at an acoustic guitar, press record, and sit back and enjoy. It's really that simple. Live sound engineers have known for years that the SM81 is a flat out killer on drum overheads. My experience with them in that context is that they show the steely body of the cymbals, again, without the annoyingly bright over-emphasized top-end that a lot of modern condenser mics do. There's a kind of 'meaty-air' of the kit that comes across. All in all, the SM81 is required equipment."

new set is better than old October 8, 2014
Reviewer: Stuart Martin from Leesburg, VA United States  
I have an old pair ('80's) of SM81's that work; but one of them has an 8 Hz oscillation (I just need to fix it).  Since they are a favorite of mine for many situations, I wanted to get a new pair while my others were awaiting repair.  I gotta say that I prefer the smooth clarity of the new ones compared to the old ones.  Thanks to Alan for making this happen.

Sm81 September 28, 2014
Reviewer: phil perkins from saranac lake, NY United States  
So far have been very satisfied using a a pair of these as overheads for acoustic ensembles at wedding ceremonies in outside environments. My consumers have been very complimentary on the quality of sound.  My partner said " they were a good purchase",  I very much agree.

Best Mic on Acoustic Instruments December 2, 2011
Reviewer: Bas  
The title says it all! This is the best mic for the price that I've ever used on acoustic instruments. This works great on acoustic guitar, cymbals and piano! Don't even hesitate to buy this microphone.
