Quick Verdict
All metal, bronze joints, a gear-lock that holds 6.6 pounds and a base wide enough for a desk most arms can’t clamp. The AA Audio Accessory Design boom arm isn’t just a mic arm. It threaded a camera mount on the same bronze fitting, so it doubles as a DSLR arm too.
Buy if you:
- Run a heavy mic like the Shure SM7B or a Blue Yeti that lighter arms sag under
- Have an extra-wide studio desk most clamps won’t fit
- Want one arm that can also hold a DSLR or sports camera for top-down shots
- Hate cables dangling across your desk
Skip if you:
- Want spring-loaded, grab-and-swing movement; the gear-lock settles in 15-degree steps, not free-floating
- Run a mic and camera over the 6.6 lb ceiling
- Dislike any plastic at all; the locking mechanisms use a plastic-feel part

An All-Metal Arm That Doubles as a Camera Mount
The first thing I noticed about the AA Audio Accessory Design boom arm was the weight in my hand, solid metal, no flex, nothing plastic except where the gears lock. This is not plastic. The whole arm is metal, with bronze parts at the joints, and that matters when you’re hanging a heavy mic off the end. You can grab today’s price on Amazon right here if you want to follow along. The headline question is simple: is this thing strong enough for heavy microphones? Short answer, yes. It’s rated to hold 6.6 pounds, and the accessory design here goes further than most arms even bother to.
What’s in the Build
The arm uses a gear-lock system instead of a spring. That’s the whole point. Spring arms weaken and sag over time. This one locks with a large gear knob and stays put. There’s a wide base plate that clamps to the edge of your desk, a long post that drops into a hole on the base, and a knob at the back that stops the arm from lifting off while still letting it spin a full 360 degrees. Universal threading on the mic end means standard mics screw right on.
Mounting It on an Extra-Wide Desk
The base is where this arm beats every competitor I’ve tested: it clamps extra-wide desks most arms physically can’t fit. I’ve got a studio desk that defeats most clamps before they even open all the way, the base plate here clamped it flat on the first try. Push it to the edge, drop the long post into the base hole, and it locks down with zero wobble. Twist the back knob and the arm won’t lift off, but it still spins a full 360 with zero issues.
There are three adjustment points: the base joint for vertical, an elbow in the middle, and the mic-end tilt. I set it up podcast-style, arm angled out at roughly 45 degrees, mic swung toward my face, and dialing in that position took maybe four knob turns total. Once locked, it didn’t move a millimeter. With the 37.4-inch reach you can swing the mic in like an old-school radio show and leave everything under it free for cameras.
The Gear-Lock Settles After You Mount It
Here’s the catch worth knowing. This is a gear-lock arm, not a spring arm, so it adjusts in rigid 15-degree steps rather than floating freely under your hand. It has no rebound, and it may settle slightly after you first mount a mic before it locks firmly in place. So always fully tighten that gear knob. If you’re used to grabbing a spring arm and swinging it anywhere mid-air, this feels different. It’s a deliberate set-and-leave system. Also, while the arm itself is all metal, the locking mechanisms do use a plastic-feel part, so it isn’t 100 percent metal end to end.

Who This Arm Is For
Podcasters and streamers running heavier mics are the obvious crowd. If you own a Shure SM7B, SM7dB, MV7, Blue Yeti, or a Rode PodMic, this is built for that weight class. The kit even includes the special threaded extender for the SM7 and SM7B, the kind of piece you normally have to hunt down online and buy separately. The first time I’ve seen a brand just hand it to you in the box. Thread it onto the bronze fitting and your mic sits a little more extended out, which a lot of SM7 users prefer. I didn’t have an SM7 on hand so I posed a universal mic on instead, but the option is there.
Mic Arm Versus a Spring-Loaded Boom Arm
Spring arms are cheaper and faster to reposition, but they’re borrowing time, the tension bleeds out and your SM7B starts drifting south within months. The gear-lock here doesn’t fade; it holds the same position on day one and day three hundred. You lose the grab-and-swing convenience, and that’s a real trade-off. But if you’re hanging a heavy studio mic, a spring arm was always the wrong tool.
Tips Before You Set It Up
Clamp it right to the edge of the desk and tighten the base plate down hard, because that big plate is what gives the whole arm its pressure and support. Run your XLR and USB-C cables through the built-in groove and the snap-in stoppers before you mount the mic, so the only cable showing is the one dangling out the end. Clean setup, nothing flopping around. And remember the camera trick: that included threading screws onto the bronze fitting, so you can mount a DSLR or sports camera for top-down or secondary angles, as long as you stay under the 6.6-pound limit. That’s the part that makes it more than a mic arm.
Pros
- All-metal arm with bronze joints, rated to hold 6.6 lbs without sagging
- Gear-lock system holds tension long term instead of weakening like a spring
- Wide base plate clamps to extra-wide desks most arms can’t fit
- Spins a full 360 degrees while the back knob keeps it from lifting off
- Includes the SM7/SM7B threaded extender and a camera mount most brands make you buy separately
- Built-in cable groove with stoppers for a clean XLR and USB-C run
Cons
- Gear-lock adjusts in rigid 15-degree steps, not free-floating like a spring arm
- May settle slightly after mounting until you fully tighten the gear knob
- Locking mechanisms use a plastic-feel part, so it isn’t all metal end to end
- Combined mic plus camera load has to stay under 6.6 lbs
Frequently Asked Questions
Will it hold a Shure SM7B without drooping?
Yes. It’s rated for 6.6 lbs and uses a gear-lock instead of a spring, which is exactly what keeps a heavy SM7B from slowly drifting down. It also ships with the SM7/SM7B threaded extender so the mic sits further out.
Can I really mount a camera on this boom arm?
Yes, the box includes a threading piece that screws onto the bronze fitting for a DSLR or sports camera. Just keep the total load under 6.6 lbs. It’s handy for top-down shots or a secondary angle.
What size desk can the clamp fit?
The base is unusually wide, wide enough to clamp an extremely wide studio desk that most boom arm clamps can’t accommodate. Mount it at the very edge of the desk and tighten it down for full support.
Does it use a standard mic thread?
Yes, it has universal threading on the mic end, so standard mics screw right on. For SM7-style mics you add the included extender first, otherwise you thread the mic on directly.
How does the cable management work?
There’s a built-in groove along the arm with snap-in stoppers. You run your XLR or USB-C cables through it so the only cable visible is the one dangling out the end. Route the cables before mounting the mic for the cleanest result.
Why does it move in steps instead of swinging freely?
Because it’s a gear-lock system, not a spring arm. It adjusts in 15-degree increments with no rebound, which is what gives it the long-term hold. If you want instant mid-air free-swinging movement, this isn’t that style.
Can it spin all the way around without coming loose?
Yes. The knob at the back stops the arm from lifting off the base but still lets it rotate a full 360 degrees. So you get the spin without worrying the whole arm pops out.
Is the whole thing metal?
The arm and joints are metal with bronze parts, built from aluminum alloy and glass-fiber nylon composite. The locking mechanisms include a plastic-feel part, so it’s mostly metal rather than 100 percent metal everywhere.
