Shure SM27 Multi-Purpose Microphone

A rugged and versatile large-diaphragm, side-address cardioid microphone, with low self-noise and extended frequency response, the Shure SM27 Condenser Microphone picks up vocal and instrument nuances with clarity. Durable Shure construction features three separate mesh layers that reduce wind and breath noise. The SM27 is equally comfortable on stage or in the studio and works just as hard as you do.


- Uniform cardioid pattern for superior off axis rejection
- Superior transient response from a low-mass large Mylar diaphragm
- Flat, neutral frequency response for natural reproduction on stage or in the studio
- 3-position switchable low-frequency filter helps reduce unwanted background noise or counteract proximity effect for consistent, extended low-end
- Durable metal construction
- Three separate mesh layers reduces wind and breath noise
- 15dB pad for performance consistency across a wider range of high SPL sources

NOTE: The SM27 SC version includes a rubber suspension shock mount, and velveteen storage pouch (U.S. Only).

"A Great Mic"
Verified Customer zZounds has verified that this reviewer made a purchase from us.
The SM27 is a versatile, ruggedly built microphone. I have used this mic to record vocal's and acoustic instruments. The acoustic recordings sounded much, much better than I was anticipating and for vocals this mic proved to be a good match for my voice. Trying to match a mic to a singers voice can be a difficult process, so I did get lucky with this Shure mic, It may not be a great match for every style of singing, no mic truly is, but this mic shouldn't disappoint anyone, especially at the 299.00 price point. For acrostics it's great! Try it for vocals and you decide. At worst it will be adequate, in my case it was perfect.
