What reviewers say
Sourced tester consensus for each — the "what people who used it think" layer, not just specs.
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, 1 lab-tested.)
Praised: Crisp, customizable 24-bit audio; Vocal Boost adds heft and body to speech; Pro features included: 32-bit float onboard recording and timecode support; IPX5 rain-proof transmitters, uncommon among rival wireless mics.
Flagged: Weak noise cancelling; traffic noise still loud even at top setting; Charging case has no room for windshields or cables; Only sold as a two-transmitter kit; no Bluetooth and no backup/safety recording.
