SUNMON Mic Boom Arm for Blue Yeti & QuadCast — Pre-installed 3/8–5/8 Adapter, Reinforced Springs

The SUNMON QuadCast Boom Arm is a heavy-duty, adjustable desk-mounted microphone arm that holds Blue Yeti, HyperX QuadCast, SoloCast, Fifine and most condenser or dynamic podcasting mics securely and with smooth positioning.

Built for streamers, podcasters and remote professionals who need a stable, flexible mic mount, this scissor-style boom arm adds reach and tidy cable routing to your desk setup. It ships with a pre-installed adapter that converts between 3/8" and 5/8" threads, a padded clamp that fits most desks, and reinforced springs for reliable height and angle retention.

How easy is it to mount and position the SUNMON mic arm?

Mounting is a quick, tool-minimal process: attach the desk clamp, thread the arm assembly in place, and connect your microphone using the included thread adapter if needed. The arm swivels at the base and the joints lock with thumbscrews so you can dial in tilt and reach without drifting.

• Desk clamp fits tabletops up to 1.89" (4.8 cm).
• Pre-installed 3/8" to 5/8" adapter for broad mic compatibility.
• Swivel base and adjustable thumbscrews for precise positioning.
• Padded clamp surface prevents desk scratches.

Will this boom arm keep my HyperX QuadCast or Blue Yeti steady during long sessions?

Yes — the SUNMON arm uses reinforced knobs and dual suspension springs to maintain position under the weight of larger condenser microphones. That reduces sag and vibration so your mic stays where you set it without producing unwanted noises from movement.

• Dual springs on each arm provide counterbalance and smooth motion.
• Reinforced tension knobs lock joints firmly in place.
• Robust metal construction minimizes wobble and flex.
• Compatible with shock mounts and common mic models to reduce handling noise.

Which microphones and accessories work with this mic arm?

The arm supports a wide range of USB and XLR microphones commonly used for streaming, podcasting and voice-over work. Because the adapter is already fitted, you can quickly connect models like HyperX QuadCast, Blue Yeti, Fifine series, Shure MV7 and SM7B (with appropriate shock mount or adapter).

• Compatible brands: HyperX, Blue, Fifine, Shure, Rode, Razer and more.
• Includes 3/8"–5/8" screw adapter for shock mounts and mic threads.
• Works with many shock mounts, pop filters and XLR/USB mics.
• Pre-installation reduces assembly steps out of the box.

How does the arm help keep a clean desk and cables under control?

The SUNMON boom arm includes integrated routing options and a slim profile that lifts your microphone off the desk, freeing valuable workspace. Cable channels and clips along the arm let you guide USB or XLR wires neatly to your interface or computer.

• Built-in routing clips tuck cables along the arm's length.
• Elevates the microphone to clear desk space and monitor areas.
• Padded clamp prevents damage to desk surfaces during adjustments.
• Swivel and tilt range reduce the need to reposition other gear.

Who is this for? The SUNMON QuadCast Boom Arm is designed for content creators, gamers, live streamers, podcasters and home office professionals who need a reliable, adjustable mic mount for heavier USB or XLR microphones. If you use a Blue Yeti, HyperX QuadCast, SoloCast, Fifine AM8 or similar mic and want improved ergonomics, reduced desk noise and cleaner cable management, this arm is an affordable, ready-to-use solution.
