Choose Alias for one direct Windows USB microphone path. Choose Alias Pro only as the documented kit: its XLR microphone connects to the included powered Stream Mixer, and the mixer connects to one or two Windows PCs. The Pro microphone is not a direct USB device, and this comparison makes no sound or value winner.
Compared by documented connections, controls and parts. No hands-on sound ranking.
We earn a commission from qualifying purchases made through the Amazon links on this page. It costs you nothing, and it never changes which microphone the path checker returns.
Alias connects straight to a Windows PC with the included USB-C-to-USB-A cable. Mute, gain, headphone output, and headphone level are on the microphone, with GG and Sonar available for supported Windows routing and effects.
Alias Pro requires its included XLR cable, powered Stream Mixer, and USB host connection. The mixer owns mute and headphone monitoring and provides the documented second-computer path. Full routing, dual-PC Streamer mode, and line output require GG and Sonar.

Regular Alias connects from the microphone's USB-C port to a Windows PC USB-A port with the included cable. The microphone is the computer input and carries its own headphone output and front controls.
Alias Pro connects microphone XLR output to the included Stream Mixer XLR input. The mixer requires its included power adapter and connects to the PC by USB. Select the mixer endpoints in Windows and Discord. A passive XLR-to-USB cable cannot replace the mixer, and the microphone itself has no direct USB host path in the reviewed manual.
Regular Alias has a microphone mute control, on-device gain, and a 3.5 mm headphone output with its own level dial. That makes mute and monitoring local to the direct USB microphone path. SteelSeries GG and Sonar add supported Windows routing and effects but are not listed as required for the basic physical connection.
Alias Pro places the microphone mute button and 3.5 mm headphone output on the included Stream Mixer. Its programmable volume dial defaults to headphone level. The manual documents a basic PC1 input and output path without Sonar, while full routing, dual-PC Streamer mode, and line-output operation require GG and Sonar. Keep Discord's selected input aligned with the intended Sonar or hardware endpoint.
Alias Pro's Stream Mixer provides two USB-C computer ports, and the standard kit lists two USB-C-to-USB-A cables. A one-PC setup uses PC1. A two-PC setup adds PC2 through the second port and uses GG and Sonar Streamer mode for the documented full workflow.
Two ports do not remove routing choices. Record which computer runs Discord, which runs the game or capture workload, where headphones connect, and which Sonar mix reaches each destination. If you do not need a second computer or mixer-level routing, the added Pro path solves no stated requirement.
Regular Alias includes the microphone, desktop stand, shock mount, boom-arm adapter for 3/8-inch and 5/8-inch threads, USB-C-to-USB-A cable, and guide. The direct Windows path needs no separate interface.
Alias Pro includes the XLR microphone, Stream Mixer, stand, shock mount, boom-arm adapter, two USB-C-to-USB-A cables, XLR cable, power adapter and regional clips, and guide. Reserve desk space and a power outlet for the mixer as well as a position for the microphone. The reviewed evidence does not establish use with an alternate interface because the microphone's standalone phantom-power requirement remains unknown.
The exact manuals list Windows PC compatibility for both models. macOS, PS5, Xbox, and Nintendo chat paths remain unknown, so the USB connector on Alias and the USB ports on the Pro mixer do not establish those hosts.
Both are documented as condenser microphones with cardioid pickup, but GamingMics has not tested either unit. The larger Pro system, XLR connection, capsule descriptions, and software options do not prove better voice quality, room rejection, or value.
Connect Alias directly to the Windows PC with its included USB cable, connect headphones to the microphone when direct monitoring is required, and select Alias in Windows and Discord. Test the on-mic mute and headphone level before adding Sonar processing or routing.
Connect the Alias Pro microphone to its Stream Mixer by the included XLR cable, power the mixer, then connect PC1 and PC2 with the two included USB cables. Install GG and Sonar for the documented Streamer mode, define which PC owns Discord, and test mixer mute, headphone monitoring, and each routed endpoint separately.
