The Signia Styletto AX is a premium prescription behind-the-ear hearing aid that earned an A grade with a SoundScore of 4.3/5 in our lab testing, ranking #21 of 39 prescription hearing aids tested. 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.

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.
