What it does well.
Studio-grade design
An all-tube design with internal springs. Friction hinges are hand-tightened and full 360° rotation covers any application. Caster stays in place after adjusting, and the robust C-clamp locks to your desk.
Hidden cable management
The USB cable runs inside the arm, so nothing hangs loose around your desk or mic.
Game streaming, podcasting & broadcast
