Fortell AI Hearing Aids vs Signia Styletto AX

The Fortell AI Hearing Aids are a premium prescription behind-the-ear device priced at $6,800, earning an A grade with a SoundScore of 6.0/5 in HearAdvisor lab testing—an exceptional result that places this device at the top of the prescription hearing aid category. Speech performance is where the Fortell AI truly distinguishes itself. Speech in noise scores an outstanding 6.0/5, a full 3.89 points above the category average of 2.11/5—the kind of margin that represents a meaningful difference in challenging listening environments like restaurants or group conversations. Speech in quiet also excels at 4.6/5, sitting 1.20 points above the category average. Music streaming performs strongly at 4.2/5, coming in 1.44 points above average for the category. The device does have a notable limitation: own-voice comfort scores just 1.5/5, falling 1.20 points below the category average. This low absolute score suggests wearers may notice occlusion effects when speaking. Feedback handling is excellent at 4.8/5, essentially matching the category average. Best suited for: Users who prioritize understanding speech in difficult listening situations and value streaming quality, and who can tolerate potential own-voice occlusion. Given the premium price point, buyers should weigh whether the exceptional speech-in-noise performance justifies the investment compared to alternatives like the Oticon Intent or Oticon Zeal, which offer strong performance at lower price points.

Priced at $4,398, this 2022 release features a distinctive slim design with rechargeable batteries and iPhone streaming capability. In our testing, the Styletto AX demonstrated strong speech clarity in quiet environments, scoring 4.0/5—0.63 points above the category average. Speech in noise performance was above average at 2.3/5 (+0.17 vs category), though this remains mixed in absolute terms, suggesting challenging listening situations may still require additional strategies. Own-voice comfort scored a solid 3.0/5, sitting 0.30 points above average. Music streaming quality measured 3.1/5, performing 0.34 points above the category average for solid audio fidelity when streaming from compatible devices. Feedback handling scored 3.9/5—solid in absolute terms, though 0.82 points below the category average of 4.72/5, which is worth noting if feedback stability is a priority. The Styletto AX has earned Expert's Choice Awards in both 2023 and 2024. However, buyers in this premium price tier should be aware that several competitors offer higher SoundScores, including the Phonak Sphere Infinio (4.98/5) and Oticon Intent (4.83/5). The Styletto AX may appeal most to those prioritizing its sleek aesthetic and strong quiet-environment speech performance over maximum scores in noise or feedback handling.
