This two-time Expert's Choice Award winner (2023 and 2024) delivers consistently strong performance across multiple listening scenarios. In our testing, the Omni 2 demonstrated particular strength in speech clarity during quiet environments, scoring 4.2/5—a strong result that sits 1.38 points above the category average. Music streaming quality also impressed at 3.6/5, exceeding the category average by 1.68 points. Speech understanding in noisy environments scored 2.3/5, which is above the category average of 1.48 but represents mixed performance in absolute terms—meaning challenging noise situations may still prove difficult. The device offers flexible power options with both rechargeable and disposable batteries, and supports streaming from both iPhone and Android devices with hands-free capability. Feedback handling is excellent at 4.5/5, essentially matching the category average, while own-voice comfort scores a solid 3.0/5. The Audicus Omni 2 is best suited for consumers seeking a premium OTC option with strong everyday speech clarity and quality streaming capabilities.
