Compact Boom Arm Extension for Studio and Live Use
The K&M 21431 Mini Boom Arm is a compact, adjustable microphone boom arm designed to mount directly onto standard mic stands. This boom arm provides essential flexibility when you need additional reach or need to reposition a microphone for overhead, side-address, or off-axis capture. Whether you're working in a professional studio, a live venue, or on-location, this is an essential tool for dialing in precise mic placement without compromising stability or space.

Perfect for Overhead and Close-Miking Applications
Engineers and musicians will appreciate how this mini boom arm helps navigate tight spaces or crowded setups. With its extendable design, it enables precise positioning for overhead drum mics, acoustic instruments, vocals, and room capture. It’s also ideal for podcasting and voiceover setups where flexible but secure boom placement is required. Its sleek black finish blends unobtrusively into both studio and stage environments.

Rugged Steel Construction Built for Reliability
Constructed from durable steel, the K&M 21431 boom arm delivers long-lasting performance and dependable support for various microphone weights. The arm holds its position once tightened and resists drift or sag over time. It's engineered for touring, studio installs, and broadcast use, where repeated setup and breakdowns demand consistent performance and reliability.

Tool-Free Adjustability and Quick Mounting
Setup is quick and simple thanks to the boom's ergonomic clutch and locking mechanisms. You won’t need tools to attach or adjust this boom arm—just thread it onto any mic stand with a 5/8" connector and you’re ready to go. The adjustable length allows for easy repositioning, so you can fine-tune your microphone angle and distance to suit changing needs on the fly.

Professional Grade for a Wide Range of Microphones
Whether you’re using lightweight pencil condensers or heavier large-diaphragm microphones, this boom arm handles it with ease. It provides the reach and control needed for stereo miking techniques, ensemble setups, drum overheads, and more—especially in studio and broadcast settings where clutter-free mic placement is critical to sound quality and visual cleanliness.

Optimized for Tight Spaces and Multi-Mic Setups
This mini boom is particularly useful in multi-mic configurations or when floor space is limited. Instead of adding an extra stand, simply extend from an existing one to get your mic where it needs to go. It’s a space-saving solution that’s especially helpful in drum rigs, orchestral recording sessions, or crowded podcast tables.
