The NT-USB Mini is more compact than the NT-USB. It also has an in-built pop filter, a magnetic base that is easily detachable, a 360-degree swing mount, and more streamlined, straightforward controls. This makes it a great portable, easy-to-use option. The NT-USB Mini also features built-in DSP that allows it to run the complex processes in RØDE Connect in real-time.  The NT-USB features a removable pop shield, a locking thread base for mounting to external shock mounts, along with a monitor mix control knob to fine tune your mic input/device output mix. Both microphones deliver pristine, studio-quality audio.
