Shure MV7+

USB now, an XLR interface later.

Razer Seiren V3 Pro

A dynamic hybrid microphone for direct USB or an XLR interface.

Before you choose

Shure MV7+

The catch: Use USB for the microphone’s DSP and headphone features. On XLR, plan processing and monitoring at the interface; those USB features do not follow the analog cable.

You need:

  • A microphone stand or boom arm

Check first:

  • For USB: a USB-C port on your computer

Razer Seiren V3 Pro

The catch: Use USB when you want the microphone’s software processing. On XLR, add an interface and do the processing there; the USB features don’t carry over to the XLR output.

Check first:

  • For USB: a USB port that fits the cable

Everything to check before you buy

Where they differ

SpecsShure MV7+Razer Seiren V3 Pro
Stand in the boxNoYes
Razer Seiren V3 Pro comes with a desk stand; Shure MV7+ needs a stand or boom arm.
Best USB recording format24-bit, 48 kHz32-bit, 96 kHz
Over USB, Shure MV7+ records up to 24-bit, 48 kHz and Razer Seiren V3 Pro up to 32-bit, 96 kHz. Both are more than a stream carries (Twitch takes AAC audio at up to 160 kbps), so the difference matters for recordings you edit.

Not enough data to compare

We haven’t confirmed a figure for one or both models on: Preamp gain needed, USB cable in the box. The site leaves these out rather than guess.

What else each needs

Shure MV7+

MV7+
For USB: a USB-C port on your computer
For XLR: an audio interface or mixer with an XLR microphone input
For XLR: an XLR cable
A microphone stand or boom arm
Wired headphones with a 3.5 mm plug
  • Check first: For USB: a USB-C port on your computer. The cable in the box has USB-C at both ends. If your computer only has USB-A ports, you need a USB-C to USB-A cable rated for the same speed.
  • Optional: For XLR: an audio interface or mixer with an XLR microphone input. A computer has no XLR input. The interface’s preamp raises the microphone’s signal and sends it to the computer over USB.
  • Optional: For XLR: an XLR cable. None comes in the box.
  • You need: A microphone stand or boom arm. No stand comes in the box; it mounts on a 5/8-inch thread.
  • Optional: Wired headphones with a 3.5 mm plug. Its headphone socket lets you hear yourself straight from the microphone, before the computer adds delay.

A boom arm, if you want it closer
Wired headphones with a 3.5 mm plug
  • Check first: For USB: a USB port that fits the cable. A USB cable is in the box, but its ends are not listed. Check it against your computer’s ports.
  • Optional: For XLR: an audio interface or mixer with an XLR microphone input. A computer has no XLR input. The interface’s preamp raises the microphone’s signal and sends it to the computer over USB.
  • Optional: For XLR: an XLR cable. None comes in the box.
  • Optional: A boom arm, if you want it closer. A desk stand is in the box. An arm lets you bring the microphone nearer your mouth without it sitting in the camera shot; check the arm fits its 5/8-inch thread.
  • Optional: Wired headphones with a 3.5 mm plug. Its headphone socket lets you hear yourself straight from the microphone, before the computer adds delay.
