Signia Styletto C&G IX vs Sontro Soundwave

The Signia Styletto C&G IX is a premium prescription hearing aid released in 2024, priced at $3,398. In our lab testing, it earned an A grade with a SoundScore of 4.6/5, ranking #11 among 39 prescription hearing aids tested. This behind-the-ear device delivers strong performance across several key metrics. Speech clarity in quiet environments scores 3.9/5, which is 0.54 points above the category average—a solid result for everyday conversations. Own-voice comfort is a particular highlight at 3.7/5, scoring a full point above average, suggesting natural sound quality when speaking. Music streaming also performs above average at 3.1/5. Speech understanding in noisy environments scores 2.5/5, which is above the category average by 0.43 points but remains mixed in absolute terms—worth considering if challenging listening situations are common. Feedback handling at 3.6/5 is solid in absolute terms, though it falls 1.12 points below the category average of 4.72/5. The Styletto C&G IX is well-suited for users who prioritize natural own-voice quality and reliable speech clarity in quieter settings. Those frequently in noisy environments or particularly sensitive to feedback may want to compare options. At this price point, competitors like the Phonak Sphere Infinio and Oticon Intent score higher overall, while alternatives like the Rexton Reach R-Li T80 at Costco offer similar sound performance at a lower price.

The Sontro Soundwave is a mid-priced OTC hearing aid that earns a B grade with a SoundScore of 3.0/5 in our lab testing. At $849, this behind-the-ear device uses disposable batteries and sits in the lower tier of OTC performance, ranking #61 of 65 devices in its category. The Soundwave's strongest attribute is own-voice comfort, scoring 3.6/5—a solid result that sits 1.09 points above the OTC category average. This makes it relatively comfortable for wearers who are sensitive to hearing their own voice sound unnatural or boomy. However, other performance areas present significant limitations. Speech clarity scores are below average in both quiet and noisy environments. Speech in quiet scores 2.7/5 (0.12 points below average), while speech in noise drops to 1.2/5 (0.28 points below average). Feedback handling is a notable weakness at 2.5/5, falling 2.04 points below the category average of 4.54/5. Perhaps most limiting is the music streaming score of 0.0/5, indicating this device does not support phone audio streaming—a feature many competitors in this price range offer. Consumers prioritizing own-voice comfort on a moderate budget may find the Soundwave acceptable, but those seeking strong speech clarity or streaming capability should consider alternatives. Several higher-performing OTC devices are available at similar or lower price points, including options like the Lexie Lumen or HearingAssist Control that deliver comparable or better overall sound quality.
