AudienSoundGrade 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 HearAdvisor's lab testing. At $89, it's positioned as an entry-level option in the visible-in-ear category, ranking #52 of 65 OTC hearing aids tested. In our testing, the Atom demonstrates mixed results across key performance areas. Its standout strength is excellent feedback handling, scoring a perfect 5.0/5—0.46 points above the category average. This means users can expect stable performance without whistling or squealing during typical wear. However, speech clarity metrics fall below category averages: speech in quiet scores 2.6/5 (0.15 points below average) and speech in noise scores a low 1.0/5 (0.48 points below average), which may limit effectiveness in challenging listening environments. The Atom does not support music streaming, scoring 0.0/5 in this category—1.92 points below the OTC average. Own-voice comfort is mixed at 2.1/5, sitting 0.41 points below the category average. These limitations are notable when compared to similarly-priced alternatives like the Elehear Beyond (4.36/5) or Apple AirPods Pro 2 (4.06/5), which offer substantially stronger overall performance. This device may suit budget-conscious consumers who prioritize basic amplification and feedback-free wear over speech clarity in noise or streaming capabilities. Those seeking stronger speech performance or music features should consider higher-scoring alternatives in this price range.

PhonakSoundGrade A

Phonak Audéo EON Sphere

The Phonak Audéo EON Sphere is a premium behind-the-ear prescription hearing aid priced at $4,398. In HearAdvisor's lab testing, it earned a SoundScore of 5.0/5 and an A grade, placing it among the top performers in the prescription hearing aid category. Speech performance stands out as this device's greatest strength. Speech in noise scored an excellent 4.5/5, a full 2.53 points above the category average of 1.96/5—a substantial margin that makes this one of the strongest performers in challenging listening environments. Speech in quiet also performed well at 4.3/5, nearly a full point above the category average. These results suggest the Audéo EON Sphere may be particularly well-suited for users who frequently encounter noisy social settings or group conversations. Music streaming delivered a solid 3.7/5, more than a point above the category average of 2.64/5, indicating above-average audio fidelity for phone-streamed content. Own-voice comfort scored 2.8/5, which sits just above the category average but reflects mixed absolute performance—users sensitive to occlusion effects should discuss this with their hearing care provider. Feedback handling scored an excellent 4.6/5 in absolute terms, though it lands slightly below the category average of 4.71/5. The Audéo EON Sphere represents Phonak's latest premium technology and delivers strong results across most metrics in our standardized testing. It's best suited for users prioritizing speech clarity in difficult listening situations who are prepared for the premium price point.
