Elgato Wave Mic Arm Low Profile

The headline says it all. You can tighten down this arm until it doesn't fall under its own weight. Once the mic is locked, the arm still can be moved easily and smoothly without falling. The screw hardware is high quality and allows swivelling the microphone and locking down the clamp in tight spaces. (The tightening lever can be pulled up, temporarily disengaging the lever from the clamp.) There aren't any parts that will bend like the spring holder plates on cheap boom arms.

A thick microphone cable can be run along the internal channel (covered by magnetic plates) and the holes at each end are large enough for an XLR connector to pass through.

The arm fits right between a computer display and keyboard and is low enough to stay out of a display-mounted camera's field of view. This is especially true using a low-profile shock mount like the Shure A55M, Gefell EH93, or one of the Studio Projects mounts e.g. Halo or B mount.
