Otofonix Helix vs Rexton Reach R-Li T80 at Costco
Side-by-side HearAdvisor lab results with SoundGrades, expert pick badges, and the same visualizations we use in product reviews.

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.

Rexton Reach R-Li T80 at Costco
The Rexton Reach R-Li T80, available at Costco for $1,500, is a behind-the-ear prescription hearing aid that earned an A grade with a SoundScore of 4.6/5 in our lab testing. This places it in the top 28% of the 39 prescription hearing aids we've tested and earned it our 2024 Expert's Choice Award. In our testing, this device demonstrated solid speech clarity performance. Speech in quiet scored 3.9/5, which is 0.46 points above the category average. Speech in noise measured 2.5/5—above the category average by 0.39 points, though still mixed in absolute terms. Own-voice comfort was a particular strength at 3.6/5, scoring 0.90 points above the category average, which may appeal to users sensitive to how their own voice sounds while wearing hearing aids. Feedback handling proved excellent at 4.8/5, just above the category average of 4.72/5. Music streaming scored 2.7/5, which is 0.06 points below the category average—a minor gap but worth noting for users who frequently stream audio content. The Reach R-Li T80 features rechargeable batteries and supports both iPhone and Android streaming with hands-free capability. At its price point, it outperforms same-priced competitors like the Jabra Enhance Pro 20 at Costco (4.01/5) and the Orka Two (4.00/5). This device is well-suited for users seeking strong overall sound performance with excellent feedback stability and above-average speech clarity through the Costco channel.
