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

Jabra Enhance Select 700
The Jabra Enhance Select 700 is a premium-priced OTC hearing aid available at $1,795, earning a B grade with a SoundScore of 3.8/5 in our lab testing. This behind-the-ear device ranks #26 of 65 OTC hearing aids tested, placing it in the top 38% of the category. In our testing, the Enhance Select 700 showed notable strengths in comfort-related metrics. Own-voice comfort scored a solid 3.7/5, measuring 1.19 points above the category average—a meaningful advantage for wearers sensitive to the sound of their own voice. Feedback handling was excellent at 5.0/5, well above the 4.54 category average, indicating reliable stability during typical wear. Speech performance presented a mixed picture. Speech in quiet scored a solid 3.1/5, sitting 0.27 points above average. However, speech in noise was a weakness at 1.0/5, falling 0.48 points below the category average—an important consideration if challenging listening environments are a priority. Music streaming scored 2.5/5, which is above the category average by 0.58 points but only mixed in absolute terms. At this price point, several alternatives delivered stronger overall performance in our testing, including the Lucid Tala (4.61/5) and Audicus Omni 2 (4.59/5). The Jabra Enhance Select 300 and Lucid Engage also achieved higher scores at lower prices. The Enhance Select 700 may suit those prioritizing own-voice comfort and feedback stability over speech-in-noise performance, but shoppers should weigh these trade-offs carefully given the premium pricing.

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.
