Signia Styletto C&G IX vs Sontro Soundwave

The Signia Styletto C&G IX is a premium prescription behind-the-ear hearing aid released in 2024, priced at $3,398. In HearAdvisor's lab testing, it earned an A grade with a SoundScore of 4.6/5, placing it in the top 25% of prescription hearing aids and ranking #10 of 36 devices in its category. This device demonstrates strong performance across most sound quality metrics in our testing. Speech in quiet scored 3.9/5, which is 0.62 points above the category average of 3.32/5. Speech in noise came in at 2.5/5—above the category average by 0.58 points, though only mixed in absolute terms. Own-voice comfort was a particular strength at 3.7/5, exceeding the category average by 0.95 points. Music streaming quality scored a solid 3.1/5, sitting 0.46 points above the category average. However, feedback handling measured 3.6/5, which while solid in absolute terms, falls 1.11 points below the category average of 4.71/5. This represents the device's primary weakness relative to competitors. The Styletto C&G IX features rechargeable batteries, iPhone and Android streaming, and hands-free calling capability. It has earned HearAdvisor's Expert's Choice Award in both 2023 and 2024. Consumers seeking similar sound performance at lower prices may want to compare the Rexton Reach R-Li T80 at Costco or the Lexie B2 Plus. This device is best suited for those prioritizing speech clarity and own-voice comfort who can accept slightly below-average feedback performance.

The Sontro Soundwave is a mid-priced OTC hearing aid priced at $849, earning a B grade with a SoundScore of 3.1/5 in HearAdvisor's lab testing. This behind-the-ear device uses disposable batteries and ranks #61 of 65 OTC hearing aids tested, placing it in the top 92% of its category. In our lab testing, the Soundwave shows a notable strength in own-voice comfort, scoring 3.6/5—a solid result that sits 1.09 points above the category average. This suggests users may experience less of the "talking in a barrel" sensation that can occur with some hearing aids. However, the device faces challenges in other key areas. Speech in quiet scores 2.7/5 (mixed, 0.12 points below average), while speech in noise registers at 1.2/5 (low, 0.28 points below average), indicating potential difficulty in challenging listening environments. The most significant limitations appear in music streaming and feedback handling. Music streaming scores 0.0/5, falling 1.92 points below the category average—a notable weakness for users who value audio entertainment. Feedback handling scores 2.5/5, which is 2.04 points below the category average of 4.54/5, suggesting the device may be more prone to whistling issues. At this price point, competitors offer substantially stronger performance. Devices like the Sony CRE-E10 and Lexie B2 Plus deliver significantly higher sound scores in the same price range. The Sontro Soundwave may suit those prioritizing own-voice comfort over speech clarity and streaming quality, but most users would benefit from exploring higher-performing alternatives at similar or lower prices.
