SteelSeries Alias vs Alias Pro: USB mic or XLR mixer kit?
Choose the Alias for a USB mic that plugs straight into a Windows PC. Choose the Alias Pro as the whole kit: its XLR mic plugs into the Stream Mixer in the box, which needs power and connects to one or two Windows PCs. The Pro's mic doesn't plug into USB by itself, and we don't pick a winner for sound or value.
Compared by the connections, controls and parts each maker lists. No hands-on sound ranking.Updated Oct 10, 2026How we choose
Alias plugs straight into a Windows PC with the USB-C-to-USB-A cable in the box. Mute, gain, a headphone jack and headphone volume are on the mic, and SteelSeries GG and Sonar add routing and effects on Windows.
The Alias Pro mic works through the XLR cable and powered Stream Mixer in the box, with the mixer plugged into your PC by USB. Mute and the headphone jack are on the mixer, and it can connect a second PC. Full routing, two-PC Streamer mode and the line output need GG and Sonar.

SteelSeries GG with Sonar for full mixing, the two-PC Streamer mode and the line output; without it the mic still works as a basic Windows input
The Alias Pro mic plugs into a mixer, not your PC
The regular Alias plugs into a USB-A port on a Windows PC with the cable from the box. The mic is what you pick on the PC, and it has its own headphone jack and controls on the front.
The Alias Pro mic plugs into the Stream Mixer with an XLR cable. The mixer runs on its own power adapter, also in the box, and connects to the PC by USB; you pick the mixer in Windows and Discord. An XLR-to-USB cable can't stand in for the mixer, and SteelSeries' manual gives the mic no way to plug into USB by itself.
The regular Alias has mute, gain and a 3.5 mm headphone jack with its own volume dial on the mic, so you mute and hear yourself right there. SteelSeries GG and Sonar add routing and effects on Windows, but SteelSeries doesn't list them as needed just to use the mic.
On the Alias Pro, the mute button and 3.5 mm headphone jack are on the Stream Mixer, and its programmable dial sets headphone volume by default. The manual says the mixer works as a basic input and output on PC1 without Sonar; full routing, two-PC Streamer mode and the line output need GG and Sonar. In Discord, pick the device you're actually using: the Sonar one or the mixer itself.
The Alias Pro's Stream Mixer has two USB-C ports for computers, and the kit comes with two USB-C-to-USB-A cables. With one PC, use PC1. With two, connect the second to PC2 and use Streamer mode in GG and Sonar for the full two-PC setup SteelSeries describes.
Two ports still leave choices to make: decide which PC runs Discord, which runs the game or the capture, where your headphones plug in, and which Sonar mix goes to each PC. If you don't use a second PC or need routing on a mixer, the Pro's extra hardware does nothing for you.
Sketch the setup: mic, XLR cable, mixer, power, PC1 and, if you use one, PC2.
Note which input you pick in Windows and Discord on each PC.
Test the mixer's mute and headphone jack before turning on Sonar routing.
Turn on Streamer mode only if you use two PCs, then test in Discord again.
Both come with a stand; the Pro adds a mixer that needs power
The regular Alias comes with the mic, a desk stand, a shock mount, a boom-arm adapter for 3/8-inch and 5/8-inch threads, a USB-C-to-USB-A cable and a guide. On Windows it needs no separate interface.
The Alias Pro comes with the XLR mic, the Stream Mixer, a stand, a shock mount, a boom-arm adapter, two USB-C-to-USB-A cables, an XLR cable, a power adapter with regional plug clips and a guide. You need desk space and a power socket for the mixer as well as a spot for the mic. SteelSeries doesn't say whether the mic needs phantom power on its own, so we can't tell you whether it works with another interface.
SteelSeries' manuals list Windows PCs for both. They don't mention macOS, PS5, Xbox or Nintendo chat, and the USB plug on the Alias or the USB ports on the Pro's mixer don't tell you either way.
SteelSeries lists both as cardioid condenser mics. We haven't tested either, and the Pro's bigger kit, XLR connection, capsule descriptions and software don't prove better voice quality, less room noise or better value.
Two complete setup examples
Regular Alias direct to one Windows Discord PC
Plug the Alias into the Windows PC with the USB cable from the box, plug headphones into the mic if you want to hear yourself, and pick Alias in Windows and Discord. Test the mute and headphone volume on the mic before adding Sonar effects or routing.
