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

Signia Silk Charge&Go IX
The Signia Silk Charge&Go IX is a premium prescription hearing aid featuring an invisible-in-ear design, currently available at $3,298. In HearAdvisor's lab testing, it earned a B grade with a SoundScore of 3.7/5, ranking #32 of 39 prescription hearing aids tested. This device demonstrates a notable strength in speech clarity for quiet environments, scoring an excellent 4.6/5—well above the category average by 1.22 points. Speech in noise performance is mixed at 2.2/5, though this still edges slightly above the category average. Feedback handling is strong at 4.3/5, providing reliable stability during typical wear, even if it falls just below the category average. The Silk Charge&Go IX has significant limitations to consider. Own-voice comfort scores low at 1.5/5, falling 1.20 points below the category average—a trade-off that may relate to the invisible form factor. Most notably, the device does not support music streaming, scoring 0.0/5 in that metric, which is 2.76 points below the category average. At this premium price point, several competitors deliver substantially higher overall performance, including the Phonak Sphere Infinio (4.98/5) and Oticon Intent (4.83/5). The Silk Charge&Go IX is best suited for users who prioritize an invisible, rechargeable design and primarily need clear speech understanding in quieter settings, while having minimal need for streaming audio content.

Starkey Genesis AI
The Starkey Genesis AI is a premium behind-the-ear prescription hearing aid released in 2023, priced at $4,798. In HearAdvisor's lab testing, it earned a B grade with a SoundScore of 3.7/5, ranking #33 of 39 prescription hearing aids tested. In our testing, the Genesis AI demonstrated excellent feedback handling, scoring a perfect 5.0/5—0.28 points above the category average. This makes it exceptionally stable during movement and physical activities. Speech in quiet performance is solid at 3.5/5, sitting 0.05 points above the category average. Speech in noise scores 2.3/5, which is 0.21 points above the category average but remains mixed in absolute terms. Own-voice comfort is a weaker area, scoring 2.2/5—0.50 points below the category average. Users sensitive to the sound of their own voice may notice this limitation. Music streaming quality is mixed at 2.8/5, essentially matching the category average with a +0.04 point difference. The Genesis AI shows meaningful improvement with professional tuning, with the normalized score rising from 3.5/5 at initial fit to 4.2/5 when tuned—a 0.8-point gain. The device offers rechargeable batteries and streaming compatibility with both iPhone and Android, plus hands-free functionality. However, at this premium price point, several competitors in the same range deliver notably higher sound performance scores, which prospective buyers should consider when evaluating options.
