AudienSoundScore 3.3Grade B

Audien Hearing Atom

The Audien Hearing Atom is a budget-priced OTC hearing aid that earns a B grade with a SoundScore of 3.3/5 in our lab testing. At $89, it represents one of the most affordable entry points into amplification, though its performance reflects that positioning with a rank of #52 among 65 OTC hearing aids tested. The Atom's standout strength is its excellent feedback handling, scoring a perfect 5.0/5—above the category average by 0.46 points. This means users can expect stable amplification without the whistling that can plague some budget devices. However, speech performance is more limited: speech in quiet scores a mixed 2.6/5 (0.15 points below category average), while speech in noise drops to a low 1.0/5 (0.48 points below average). A significant limitation is the complete lack of music streaming capability, scoring 0.0/5—nearly 2 points below the already-modest category average. Own-voice comfort also falls below average at 2.1/5. These results suggest the Atom is designed purely for basic amplification rather than multimedia use. The Atom may suit buyers seeking the most affordable path to mild amplification who prioritize stability over advanced features. However, several competitors in the same price range offer substantially better performance—some scoring a full point higher. Those willing to consider alternatives may find meaningfully better speech clarity and additional capabilities without significant price increases.

PhonakSoundScore 5.0Grade A

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.
