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.

VivtoneSoundScore 3.1Grade B

Vivtone Xpure Hearing Aid

The Vivtone Xpure is a behind-the-ear OTC hearing aid priced at $549, earning a B grade with a SoundScore of 3.1/5 in HearAdvisor's lab testing. This places it in the lower tier of the OTC category, ranking #57 of 65 devices tested. The Xpure demonstrates a notably uneven performance profile. Its standout strength is music streaming, scoring an excellent 4.4/5—a remarkable 2.48 points above the category average. This makes it one of the better choices for users who prioritize audio entertainment through their hearing aids. Speech in quiet performs just slightly above category average at 2.9/5, though this remains mixed in absolute terms. However, the device shows significant weaknesses in several areas. Own-voice comfort scores a low 0.8/5, falling 1.71 points below the category average—a notable concern for users sensitive to how their own voice sounds. Speech in noise at 1.2/5 sits below the category average, and feedback handling, while solid at 3.3/5, still falls 1.24 points below what typical OTC devices achieve. The Xpure improves meaningfully with professional tuning, jumping from a normalized Initial Score of 3.0/5 to a Tuned Score of 3.5/5. Shoppers prioritizing music streaming may find value here, but those seeking balanced speech performance or natural own-voice quality should consider alternatives like the Linner Nova Earbud or Nuheara IQBuds Max, which offer higher overall scores at lower prices.
