- Preamp bypass switch to revert to original SM7B performance.
- Bass roll-off and mid-range emphasis (presence boost) EQ switch controls.
- Superior rejection of electromagnetic hum, optimized for shielding against broadband interference emitted by computer monitors.
- Internal "air suspension" shock isolation virtually eliminates mechanical noise transmission.
- Highly effective pop filter eliminates need for any add-on protection against explosive breath sounds, even for close- up vocals or narration.
- Yoke mounting with captive stand nut for easy mounting and dismounting provides precise control of microphone position.
- Classic cardioid polar pattern, uniform with frequency and symmetrical about axis, to provide maximum rejection and minimum coloration of off-axis sound.

Hey guys, it's Luis from zZounds with some things to know about the Shure SM7DB vocal dynamic microphone.
The biggest update with this model is that it now has a built-in preamp. In the past, you would have needed an external preamp like a Cloudlifter to boost the signal, but now it's built right in—making it much easier to use.
You also get the option for +18dB or +28dB of gain, giving you plenty of flexibility depending on your setup.
Whether you're a podcaster, musician, or streamer, this mic delivers pro-level sound in a simple, convenient package.

"Absolutely Incredible"
Verified Purchaser
zZounds has verified that this reviewer purchased this specific product from us.
I've owned this microphone for a little over a year now. I've previously owned the Shure SM7B, but never had enough headroom for the microphone to shine to its full potential with the interface I was recording through. This micrphone changes all that completely. I am recording through a Scarlett 2i2 interface and I couldn't be happier with the results. My vocals range from everything from RnB to pop, metal with false chord screams, hip hop, and so on, and this microphone shines in quality with all of those genres. I use it as a daily voice comms microphone for both work and when gaming while in Discord. The great thing about the Shure SM7dB is it removes the need for the Cloud Lifter. Sure, you might save a few bucks buying the SM7B and the Cloud Lifter, but this is one less thing you have to worry about in the chain.
