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.

VivtoneSoundGrade B

Vivtone Xpure Hearing Aid

The Vivtone Xpure is a mid-priced behind-the-ear OTC hearing aid priced at $549 that earns a B grade with a SoundScore of 3.1/5 in our lab testing. Ranking #57 of 65 OTC hearing aids tested, this 2023 release offers a mixed performance profile with one notable strength. The Xpure's standout feature is its music streaming quality, scoring an excellent 4.4/5—a full 2.48 points above the OTC category average. For users who prioritize listening to music or audio content through their hearing aids, this represents genuinely strong performance. Speech clarity in quiet environments scores 2.9/5, slightly above the category average but mixed in absolute terms. However, the Xpure shows limitations in several key areas. Speech understanding in noisy environments scores just 1.2/5, falling 0.29 points below the category average. Own-voice comfort is notably low at 0.8/5, sitting 1.71 points below average—users may find their own voice sounds unnatural or boomy. Feedback handling scores a solid 3.3/5 in absolute terms, though this still falls 1.24 points below the strong OTC category average of 4.54/5. The Xpure improves with professional fitting, with the normalized score increasing from 3.0/5 initially to 3.5/5 when tuned. Buyers seeking similar sound quality at lower prices may want to consider alternatives like the Linner Nova Earbud or Nuheara IQBuds Max, both of which scored higher in our testing at lower price points. The Xpure is best suited for users who prioritize excellent music streaming and can accept trade-offs in speech-in-noise performance and own-voice comfort.
