Overview

The Elgato Wave Mic Arm LP White is a studio-grade boom arm engineered specifically for creators who need their microphone close but out of sight. Its defining feature is the low-profile design, which routes the arm below the user's shoulder line rather than arching overhead. This keeps the arm and microphone out of webcam frames and camera shots — a meaningful advantage for streamers, podcasters, and video call professionals who want clean visuals without sacrificing audio quality. The 740mm (29.1-inch) horizontal reach is generous enough to span most desks, bringing the microphone from a rear-mounted clamp to a comfortable speaking position.

Build quality is a clear priority in the design. The all-metal construction incorporates anti-torsion engineering to prevent the arm from sagging, twisting, or drifting once positioned, even under the full 2 kg load capacity. Cable management is handled through integrated channels with magnetic covers that snap on and off, keeping XLR or USB cables hidden inside the arm while making them accessible for setup changes. The arm offers 360-degree horizontal rotation at both the base and elbow joints, along with 90 degrees of upward and 60 degrees of downward vertical rotation, providing precise control over microphone placement. The expandable desk clamp fits surfaces up to 60mm thick and holds securely without marking the desk surface.

Pros & Cons

👍 Pros

  • Low-profile design sits below the shoulder line, keeping webcam and camera views unobstructed
  • 740mm horizontal reach comfortably spans large desks without repositioning the clamp
  • All-metal, anti-torsion construction prevents unwanted drooping or twisting under load
  • Magnetic cable channel covers keep wiring hidden while remaining easy to open for adjustments
  • 360-degree horizontal and 90-degree vertical rotation provides precise microphone positioning

👎 Cons

  • 2 kg maximum load excludes heavier professional microphones and heavy shock mount combinations
  • Low-profile positioning may require the microphone to be further from the mouth compared to overhead boom arms
  • White matte finish, while clean-looking, may show desk scuffs or marks over time
  • The desk clamp's 60mm maximum limits use on thicker desks or countertops without modification
