JabraSoundScore 3.7Grade B

Jabra Enhance Plus

The Jabra Enhance Plus is a mid-priced OTC hearing aid priced at $799, earning a B grade with a SoundScore of 3.7/5 in our lab testing. This visible-in-ear device ranks #28 of 65 OTC hearing aids tested, placing it in the top 42% of its category. In our testing, the Enhance Plus demonstrated notable strengths in speech clarity and audio streaming. Speech in quiet scored a strong 4.2/5, measuring 1.36 points above the category average. Music streaming performance was equally impressive at 3.8/5, a full 1.88 points above average—making this a solid choice for users who prioritize phone audio streaming. Feedback handling was excellent at 4.7/5. However, the device has a significant weakness: own-voice comfort scored just 0.3/5, falling 2.21 points below the category average. This suggests pronounced occlusion effects that may make the user's own voice sound boomy or unnatural. Speech in noise performance was mixed at 2.1/5—above the category average by 0.62 points, but still limited in absolute terms for challenging listening environments. The Enhance Plus showed meaningful improvement with tuning, jumping from a normalized Initial Score of 3.6/5 to a Tuned Score of 4.2/5. Buyers should note that several competitors in the same price range score higher, including the Sony CRE-E10 at 4.66/5. This device is best suited for users who prioritize music streaming and speech clarity in quieter settings, and who can tolerate own-voice occlusion.

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.
