Jabra Enhance Select 300
The Jabra Enhance Select 300 is a premium OTC hearing aid priced at $1,695 that earns an A grade with a SoundScore of 4.1/5 in our lab testing. This behind-the-ear device ranks #17 among 65 OTC hearing aids tested, placing it in the top 25% of its category. In our testing, the Enhance Select 300 demonstrates notable strengths in speech clarity for quiet environments, scoring 0.85 points above the OTC category average. Feedback handling is excellent at 5.0/5, and own-voice comfort scores a solid 3.5/5—nearly a full point above average for the category. Music streaming performance, while above average for OTC devices, remains mixed in absolute terms at 2.6/5. The device's main limitation appears in challenging listening environments. Speech-in-noise performance scored 1.5/5, which is low in absolute terms and essentially matches the category average. Users who frequently encounter noisy restaurants, busy offices, or crowded gatherings may find this a meaningful constraint. The Enhance Select 300 is best suited for individuals who primarily need improved hearing in quieter settings such as home conversations, one-on-one meetings, or watching television. It offers reliable streaming to both iPhone and Android devices, rechargeable batteries, and hands-free functionality. Shoppers seeking stronger noise performance at this price point may want to compare alternatives like the Lucid Tala or Audicus Omni 2, which scored higher overall in our testing.

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.
