Side-by-side HearAdvisor lab results with SoundGrades, expert pick badges, and the same visualizations we use in product reviews.

Elehear Alpha
The Elehear Alpha is a budget-priced OTC hearing aid released in 2023, earning a B grade with a SoundScore of 3.3/5 in our lab testing. At $299, it sits in the most affordable price tier for over-the-counter devices, though its overall performance ranks #44 of 65 OTC hearing aids tested. This behind-the-ear device presents a distinctive performance profile with notable strengths and weaknesses. Music streaming stands out as exceptional, scoring 4.2/5—a strong result that's 2.28 points above the category average. Feedback handling is also excellent at 5.0/5, meaning users can expect stable performance without whistling issues. However, core speech understanding metrics fall below category norms: speech in quiet scores a mixed 2.1/5 (0.73 points below average), while speech in noise is low at 1.0/5 (0.48 points below average). Own-voice comfort is a significant limitation, scoring just 0.7/5—a low result that's 1.81 points below the category average. This suggests users may experience noticeable occlusion effects when speaking. The Elehear Alpha is best suited for budget-conscious consumers who prioritize music and media streaming over speech clarity in challenging environments. Those needing stronger speech performance should consider alternatives like the Elehear Beyond or Olive Union Air, which offer better sound scores at similar or lower price points. For users primarily streaming podcasts, audiobooks, or music who have modest speech amplification needs, the Alpha's excellent streaming quality and feedback stability may justify its trade-offs.
Choice

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.
