Audicus Omni 2
The Audicus Omni 2 is a premium-priced behind-the-ear OTC hearing aid available for $1,898. With a SoundScore of 4.6/5 and an A grade, it ranks #5 among 65 OTC hearing aids tested, placing it in the top 6% of its category. In our lab testing, the Omni 2 demonstrates strong speech clarity in quiet environments, scoring 4.2/5—well above the category average by 1.38 points. Speech in noise performance is more modest at 2.3/5, which is above the category average by 0.79 points but mixed in absolute terms. This pattern suggests the device handles everyday conversations well while challenging listening situations may still present difficulty. Music streaming is a particular strength, scoring 3.6/5 and exceeding the category average by a substantial 1.68 points. Feedback handling is excellent at 4.5/5, virtually matching the category average. Own-voice comfort scores a solid 3.0/5, which is 0.49 points above average for OTC devices. The Omni 2 offers both rechargeable and disposable battery options, along with streaming compatibility for iPhone and Android devices with hands-free capability. It has earned Expert's Choice Awards for both 2023 and 2024. Consumers seeking alternatives in this price range may also consider the similarly-priced Lucid Tala, while the lower-priced Lexie B3 offers competitive performance for those with tighter budgets.

Autiphon U0 Series
The Autiphon U0 Series is a budget amplification product priced at $99, earning a C grade with a SoundScore of 2.9/5 in HearAdvisor's lab testing. This visible-in-ear device ranks #6 of 8 amplification products tested, placing it in the top 63% of its category. In our testing, the U0 Series demonstrates a mixed performance profile. Its standout strength is excellent feedback handling, scoring a perfect 5.0/5—well above the category average by 0.72 points. This means users are unlikely to experience whistling or squealing during normal use. Speech in quiet environments scores 2.3/5, which is 0.22 points above the category average, though still only mixed in absolute terms. The device shows notable limitations in other areas. Speech in noise performance is low at 1.0/5, falling 0.37 points below the category average—meaning challenging listening environments like restaurants or gatherings will be difficult. Music streaming capability is essentially non-functional, scoring 0.0/5 and sitting 1.16 points below category average. The Autiphon U0 Series is best suited for budget-conscious users who primarily need basic amplification in quieter settings and prioritize freedom from feedback issues. Those who frequently encounter noisy environments or want to stream music should consider alternatives. At this price point, the HSKLock Hearing Aid offers slightly higher overall performance at 2.98/5.
