SUNMON Boom Arm for Fifine K688 Mic with Adapter and Cable Sleeve

Made of metal, the SUNMON boom arm gives a Fifine K688 microphone an adjustable position above your desk. Its dual suspension springs support smoother positioning and help protect the mic from shaking or sinking, while the cable sleeve and included ties keep the connection cable organized along your setup.

Choose this arm when you want to move a microphone into position for speaking, rather than keep it fixed on a desk stand. The desk clamp makes it suited to a desktop recording or streaming workspace, and the adjustable arm helps tailor mic placement to the task.

The suspension design is useful when you need to reposition the microphone during a recording session. Its springs help keep the arm steady and reduce shaking, sinking, and unwanted noise. The cable sleeve and ties provide a simple way to route the K688 connection cable neatly instead of leaving it loose across the desktop.

Requirements

This arm is designed for the Fifine K688 mic. The clamp attaches to a desktop up to 1.8"/4.6cm thick, so its mounting point should have enough edge space for a secure fit. Keep the microphone and any attached hardware within the arm’s maximum supported weight of 3 Pound (1.4 KG). The package includes the arm and mounting clamp, the Fifine microphone is not included.

Practical tips

Attach the clamp to a stable desk edge, then position the arm so the microphone can be brought close for speaking and moved aside when you need more workspace. Route the connection cable through the sleeve and use the cable ties to manage slack. This helps keep the area around a keyboard or other desk equipment clearer while allowing the mic to move with the arm.

The included 3/8" to 5/8" adapter supports the listed microphone-arm connection, while the K688-specific fit keeps the product focused on that setup. For a fixed microphone position, a stationary stand offers a different approach, this boom arm is the more practical format when you want to adjust height or angle without relocating the desk mount.

Final verdict

For a Fifine K688 desk setup, this SUNMON arm combines adjustable placement, a clamp-mounted base, and cable management in one focused accessory. Its metal construction, dual suspension springs, adapter, and included cable ties make it useful for keeping a microphone accessible during recording or streaming while preserving more open space on the desktop.
