Hi there! Unfortunately, it cannot. The second you plug in the wire, a hardware cutoff switch turns off the wireless functionality.

The only SteelSeries products I’m aware of that allow mixing of multiple signals are the Arctis 3 Bluetooth, Arctis 9X, and Arctis Pro Wireless. In all three of those cases, you can use one Bluetooth signal and one other signal.

The Arctis 3 Bluetooth was advertised early on as being a great choice for Switch gameplay since you could hear game audio wired from the Switch and use the Bluetooth for chat on your phone, so that’s probably the one worth looking into…though you will be wired to the Switch.

Hope that helps you out! Thanks for reading.
