A boom arm can move a USB microphone closer to your mouth while freeing desk space, but compatibility is not universal. Check microphone plus shock-mount weight, thread size, included adapters and desk-clamp clearance before ordering.
I have not personally tested these arms.
Quick picks
- Best low-profile option — Elgato Wave Mic Arm LP. A creator-desk arm designed to run below monitor level. Check on Amazon Australia.
- Best traditional studio arm — RØDE PSA1. A full-height arm with a clearly defined supported load range. View on Amazon Australia.
- Best budget-style arm with adapters — InnoGear Desk-Mount Boom Arm. A suspension arm supplied with several common thread adapters. See it on Amazon Australia.
1. Elgato Wave Mic Arm LP — best low-profile option
Best for: creator desks where the arm should run below monitor level.
The linked low-profile model uses integrated cable channels and desk-clamp mounting. Check the current Amazon Australia listing for its supported microphone weight and desk-thickness limits before ordering.
Trade-off: low-profile geometry is less suitable if you want the microphone to descend from well above the monitor. Avoid it if your microphone/load or desk falls outside the listed limits.
2. RØDE PSA1 — best traditional studio arm
Best for: buyers who want a traditional full-height studio boom arm with both clamp and desk-insert mounting hardware.
RØDE specifies support for a combined microphone and shock-mount/clip weight of 700g to 1.1kg. The PSA1 includes a desk clamp and threaded desk insert; the clamp supports desks up to 55mm thick and the insert up to 70mm.
Trade-off: its supported load has both a minimum and maximum. Avoid it if your complete microphone setup sits outside the 700g–1.1kg range or your desk cannot accept either mounting method.
3. InnoGear Desk-Mount Boom Arm — best budget-style option with adapters
Best for: buyers who want a conventional suspension arm bundled with several common thread adapters.
The current listing includes 5/8-to-3/8-inch and 5/8-to-1/4-inch adapters and states a supported load around 3.3 lb under its specified conditions.
Trade-off: included adapters do not guarantee every microphone physically fits. Avoid it if your mic exceeds the stated load or requires proprietary mounting hardware.
What to check before buying
- Total load: include the microphone, shock mount, pop filter and any mounting accessories.
- Thread: 3/8-inch and 5/8-inch are common, but adapters or proprietary mounts may be required.
- Desk clamp: check desk thickness, edge shape and clearance underneath.
- Arm geometry: low-profile and conventional arms occupy different areas around monitors.

Buyer’s guide
Choose Elgato when you want the arm below monitor height, RØDE for a traditional studio-style arm with a clearly defined supported weight range, or InnoGear for a simpler adapter-rich suspension setup.
FAQ
Do all microphones use the same thread?
No. Check the microphone, shock mount and arm thread before buying.
How much weight should an arm hold?
The complete mounted setup must stay within the manufacturer’s supported range.
Will a boom arm fit any desk?
No. Clamp opening, desk thickness, edge shape and clearance all matter.
Conclusion
Choose by arm geometry, supported load and mounting compatibility rather than assuming a boom arm is universal.
