The Phonak Audéo Lumity is a premium prescription behind-the-ear hearing aid released in 2022, priced at $4,398. In HearAdvisor's independent lab testing, it earned an A grade with a SoundScore of 4.1/5, ranking #23 among 39 prescription hearing aids tested. This device demonstrates particular strength in music streaming, scoring 4.1/5—a strong result that sits 1.34 points above the category average. Feedback handling is excellent at 5.0/5, providing reliable stability during wear. Speech clarity in quiet environments is solid at 3.7/5, measuring 0.29 points above average for prescription aids. However, the Lumity shows notable limitations. Own-voice comfort scores just 1.0/5, falling 1.70 points below the category average—a significant weakness that may affect user satisfaction during conversations. Speech understanding in noisy environments, while technically above average by 0.04 points, remains mixed in absolute terms at 2.1/5. The Audéo Lumity includes rechargeable batteries, streaming compatibility with both iPhone and Android devices, and hands-free calling capability. It received HearAdvisor's Expert's Choice Award in both 2023 and 2024. This hearing aid may suit users who prioritize music enjoyment and streaming quality, though those sensitive to own-voice perception or frequently in noisy environments may want to explore alternatives in this price tier.

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.
