## What reviewers say

**DJI Mic 3** — Two whitelisted testers (TechRadar, SoundGuys) hands-on reviewed the DJI Mic 3; both are qualitative with no lab-measured numbers. TechRadar names it Editor's Choice, calling it a class-leading upgrade over the Mic 2 that is also cheaper at launch. SoundGuys rates it 7.8, praising the sound and small size but faulting the dropped 3.5mm jack, obvious branding, and the DJI MIMO app, framing it as effectively a 'DJI Mic Mini 2 in disguise.'
