Phonak Sphere Infinio
The Phonak Sphere Infinio is a premium behind-the-ear prescription hearing aid released in 2024, priced at $4,898. In our lab testing, it earned an A grade with a SoundScore of 5.0/5, placing it at #2 among 39 prescription hearing aids tested—within the top 3% of its category. The standout performance comes in speech clarity. Speech in noise scores an excellent 4.7/5, a remarkable 2.59 points above the category average of 2.11/5. Speech in quiet also impresses at 4.5/5, sitting 1.07 points above average. For anyone who struggles to follow conversations in restaurants, gatherings, or busy environments, this device delivers measurably superior intelligibility compared to most alternatives we've tested. Music streaming quality is strong at 4.0/5, exceeding the category average by 1.24 points—a meaningful advantage for users who value audio fidelity when streaming from phones. However, own-voice comfort is mixed at 2.3/5, falling 0.40 points below the category average, which may affect how natural your own speech sounds. Feedback handling, while solid in absolute terms at 3.6/5, sits 1.12 points below the category average of 4.72/5. The Sphere Infinio is best suited for users prioritizing exceptional speech understanding, particularly in challenging noise environments, and who are willing to invest at the premium tier. Those especially sensitive to own-voice quality or requiring maximum feedback stability may want to compare alternatives like the similarly-priced Oticon Intent or the lower-priced Phonak Audéo EON Sphere.

RCA In-Ear
The RCA In-Ear is a budget-priced OTC hearing aid available for $249, earning a C grade with a SoundScore of 2.8/5 in our lab testing. This places it near the bottom of the OTC hearing aid category, ranking 64th out of 65 devices tested. In our standardized testing, the RCA In-Ear shows a mixed performance profile. Its standout strength is excellent feedback handling, scoring a perfect 5.0/5—0.46 points above the category average. This means users are unlikely to experience whistling or squealing during normal wear. Own-voice comfort scores 2.6/5, which is essentially at the category average (+0.09 points), offering mixed but acceptable performance for how your own voice sounds while wearing the devices. However, the core speech performance metrics present significant limitations. Speech in quiet scores just 1.0/5, falling 1.79 points below the category average, and speech in noise also scores 1.0/5, sitting 0.48 points below average. Music streaming scored 0.0/5, indicating this device is not suitable for audio entertainment purposes. At this price point, buyers have considerably stronger options. Competitors like the Lucid Enrich Pro and JLab Hear OTC offer better sound performance at lower prices. The RCA In-Ear may appeal to those prioritizing feedback-free wear above speech clarity, but most users seeking meaningful hearing benefit should consider higher-performing alternatives in this budget segment.
