Signia Styletto AX Hero
SigniaSoundScore 4.3Grade A

Signia Styletto AX

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.

Starkey Edge AI RIC Hero
StarkeySoundScore 4.3Grade A

Starkey Edge AI RIC

The Starkey Edge AI RIC is a premium prescription hearing aid released in 2024, priced at $5,000 and earning an A grade with a SoundScore of 4.3/5 in our lab testing. This behind-the-ear device ranks #20 of 39 prescription hearing aids tested, placing it in the top 49% of its category. In our testing, the Edge AI RIC demonstrates notable strengths in speech clarity and music streaming. Speech in quiet scores a strong 4.1/5, measuring +0.68 points above the category average. Music streaming stands out at 3.8/5, a solid score that sits +1.04 points above what we typically see in prescription devices—making it a compelling choice for users who value phone audio quality. Speech in noise scores 2.6/5, which is above the category average by +0.54 points but remains mixed in absolute terms. Feedback handling is excellent at 4.7/5, though this sits just below the category average of 4.72/5. Own-voice comfort scores 2.8/5, slightly above average but mixed overall—something to consider if own-voice naturalness is a priority. The device showed meaningful improvement from tuning: the normalized Initial Score of 4.2/5 rose to 4.7/5 after professional fitting, a +0.5 point gain. As a 2024 Expert's Choice Award winner, the Edge AI RIC offers strong everyday speech performance and standout streaming capabilities. However, buyers in this premium price tier should note that several competitors—including the Phonak Sphere Infinio and Oticon Intent—achieve higher overall scores. The Edge AI RIC is best suited for users who prioritize music streaming quality and strong speech clarity in quieter environments.
