CearvolSoundScore 3.7Grade B

Cearvol Diamond X1

The Cearvol Diamond X1 is a budget-priced OTC hearing aid that earned a B grade with a SoundScore of 3.7/5 in our lab testing, placing it in the top 45% of OTC devices. At $199, it represents an accessible entry point for those exploring hearing amplification. The Diamond X1's standout performance is in music streaming, scoring 4.1/5—a strong result that sits 2.18 points above the OTC category average. This makes it notably capable for users who prioritize audio entertainment through their hearing devices. Feedback handling is also excellent at 4.5/5, meaning users should experience minimal whistling during normal use. However, speech performance presents limitations. Speech in quiet scores a mixed 2.8/5, and speech in noise registers at 1.7/5. While both metrics technically sit above category averages (+0.03 and +0.22 points respectively), they remain low in absolute terms—important context for anyone prioritizing conversation clarity. Own-voice comfort is another weakness, scoring 1.7/5, which is 0.81 points below the category average and may affect how natural users sound to themselves. The Diamond X1 is best suited for budget-conscious consumers who value music streaming quality and aren't heavily reliant on challenging listening environments. Those who prioritize speech understanding in noise or natural own-voice perception may want to consider alternatives in this price range, such as the higher-scoring Elehear Beyond or Apple AirPods Pro 2.

JabraSoundScore 4.1Grade A

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.
