## What reviewers say

**Saramonic Ultra** — Only one whitelisted tester (TechRadar) published a hands-on Saramonic Ultra review, based on a week of real-world use with an iPhone 13 and Lumix GH6. It rates the kit a viable, affordable pro-friendly option, praising crisp customizable 24-bit audio (Vocal Boost adds heft), 32-bit float onboard recording, timecode support and rain-proof IPX5 transmitters, but flags weak noise cancelling that still leaves traffic and wind audible at the top setting. No lab measurements were taken. (1 sourced review.)
