Questions about this item

Does the KA-538 need a separate power outlet or does it draw power from the USB or Type-C port?

It draws power directly from the USB or Type-C port on your computer, monitor, phone or tablet, so no separate power adapter is required.

Will the spring-loaded clip fit a monitor bezel that is 1.26 inches thick?

Yes, the clip is designed to attach securely to bezels up to 1.26 inches thick on monitors, laptops or gaming displays.

How can I confirm the speaker is receiving audio and the mute function is off after plugging it in?

Turn the volume wheel until sound is audible; the one-touch mute button silences audio instantly when pressed, so you can verify it is active or inactive by listening.
