Jabra Enhance Select 300 Hero
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.

Otofonix Helix Hero
OtofonixSoundScore 2.6Grade C

Otofonix Helix

The Otofonix Helix is a behind-the-ear amplification product released in 2021, priced at $695. In HearAdvisor's lab testing, it earned a C grade with a SoundScore of 2.6/5, ranking #7 of 8 devices in the Amplification Product category. The Helix demonstrates one clear strength: excellent feedback handling at 5.0/5, which is 0.72 points above the category average. This means users are unlikely to experience whistling or squealing during typical use. However, the device shows significant limitations in other areas. Speech clarity scores are low in both quiet (1.0/5) and noisy (1.0/5) environments, falling below category averages by 1.11 and 0.37 points respectively. Own-voice comfort is notably weak at 0.3/5 in the tuned configuration, measuring 2.34 points below the category average. This suggests users may find their own voice sounds unnatural or boomy. Music streaming capability scored 0.0/5, indicating this device is not suitable for those who want to stream audio content. Consumers in this price range have substantially higher-performing alternatives available. The Sennheiser Conversation Clear Plus scores 4.04/5, while the HearingAssist Micro achieves 3.54/5. Those seeking similar performance at a lower price point might consider the Otofonix Encore or RCA Micro. The Helix may appeal to users who prioritize feedback-free amplification over speech clarity or streaming features, but most shoppers will find better value elsewhere in this category.
