Contents
A boom arm keeps the mic closer to your mouth, out of the webcam frame and off the desk surface — often the biggest upgrade after the microphone itself. Scissor, low-profile or gas-spring, clamp size and load rating decide whether the arm holds and whether your sightlines stay clear. This guide covers the criteria and five models currently available on Amazon.de.
Transparency: We have not tested these arms ourselves. Specs and features come from Elgato, TONOR, CAHAYA and RØDE product pages plus verified Amazon.de listings (as of October 2026). We do not list prices because they change constantly.
Why a boom arm instead of a desk stand?
The included stand works, but it eats desk space and often sits too far away. An arm:
- puts the capsule at a close working distance (clearer voice, less gain)
- keeps the mic out of the webcam and monitor sightline
- helps isolate keyboard/desk thumps (especially with a shock mount)
- swings aside when you need the desk clear
For the mic itself: Gaming Microphone Buying Guide. Framing: Gaming Webcam. Desk thickness and clamp clearance: Gaming Desk.
What matters most
1. Load capacity vs mic weight
Manufacturers publish a maximum load (mic + shock mount + pop filter + cable pull). USB desktop mics are often a few hundred grams; broadcast dynamics plus a mount can be much heavier. Leave headroom: pick an arm rated above your full setup. Elgato Wave Mic Arm LP lists up to 2 kg; Wave Mic Arm Pro up to 3 kg; TONOR T20 up to 1.8 kg; T40 2 kg at 90°; CAHAYA CMC0500 up to 2.5 kg (manufacturer/Amazon figures).
2. Scissor vs low-profile vs gas spring
| Type | Typical trait | Choose when… |
|---|---|---|
| Scissor (spring) | high arc, classic studio look | you want the mic over keyboard/monitor |
| Low-profile | arm sits below shoulder/webcam line | you need clear facecam and dual-monitor view |
| Gas spring (e.g. Pro) | holds smoothly without constant screw tweaks | you reposition often and want quiet motion |
Low-profile arms (Elgato LP, CAHAYA) stay flatter on the desk — important for webcam framing. Classic scissors need more vertical clearance.
3. Clamp: thickness, overhang, grommet
Most gaming arms use a desk clamp. Typical openings: Elgato LP/Pro and TONOR T20 up to about 60 mm desk thickness; TONOR T40 up to 6 cm; CAHAYA lists 0–10 cm. Also check:
- underside clearance (cross-bracing, wall-flush desks)
- rubber/silicone pads to protect the surface
- whether a grommet mount is included instead of (or as well as) a clamp — some pro arms (e.g. RØDE PSA1+) ship both
Verify glass tops and unusually thin/thick desks before buying.
4. Cable management
Built-in cable channels (open, covered or magnetic) keep USB/XLR runs along the arm. Elgato LP/Pro use channels with magnetic covers; CAHAYA an open channel plus tray; TONOR often includes cable ties. Without channels, use ties or Velcro — or the cable ends up in the webcam shot.
5. Thread adapters (3/8″–5/8″)
3/8″ and 5/8″ are standard; many arms include adapters. Elgato arms often start at 1/4″ on the ball head and include 3/8″ and 5/8″ adapters. Match shock mount and mic threads to what’s in the box.
6. Desk clearance and camera sightlines
Low-profile: Elgato publishes lower/upper arm desk clearance (LP: about 70 mm / 160 mm per specs). Scissor arms rise higher — sketch monitor height and facecam angle first. Horizontal reach is typically about 65–78 cm depending on model.

Matching audio interface
If you mount an XLR mic on the arm, you also need an audio interface. What matters there (gain, phantom power, loopback) is covered in the audio interface buying guide. One example that pairs well with the Elgato arms (specs per manufacturer, not tested by us):
Example model
Interface for dynamic mics: Elgato Wave XLR MK.2
One XLR input with 80 dB of gain according to Elgato, switchable phantom power, tap-to-mute and the Wave Link software as a mixer. Sold and shipped by Amazon, in stock (checked October 2026).
- Input
- 1 × XLR
- Gain
- 80 dB
- Connection
- USB-C
- Weight
- 320 g

Checklist before you buy
- Weighed mic + shock mount + pop filter — is the arm rated above that?
- Scissor (high) or low-profile (under the camera)?
- Measured desk thickness and underside overhang?
- 3/8″ / 5/8″ / 1/4″ — which adapters ship, what does the mount need?
- Need a cable channel for a clean webcam frame?
- Sketched facecam and monitor sightlines?
FAQ
Is the included desk stand enough?
For a start, yes. Once the mic sits too far away or blocks the shot, an arm usually helps more than a pricier mic alone.
Scissor or low-profile?
Low-profile when webcam/monitors need a clear view. Scissor when you want a classic overhead approach to the mouth.
What about threads?
Many mounts use 3/8″ or 5/8″. Check the box — Elgato typically includes 3/8″ and 5/8″ for a 1/4″ head.
Will it hold heavy broadcast mics?
Only within the stated load and reach. For heavy kits prefer higher ratings (e.g. Pro up to 3 kg) and set spring/gas tension correctly.
Do I still need a shock mount?
Yes for keyboard and desk thumps. Some USB mics have built-in isolation; external mount plus arm is the studio combo.
