Lucid Ultra 128  Hero
LucidSoundScore 4.4Grade A

Lucid Ultra 128

The Lucid Ultra 128 is a premium behind-the-ear prescription hearing aid priced at $5,000, earning an A grade with a SoundScore of 4.4/5 in our lab testing. It ranks #17 among 39 prescription hearing aids tested, placing it in the top 41% of its category. Speech performance is where the Lucid Ultra 128 truly excels. In our lab testing, speech in quiet scored a strong 4.3/5, which is 0.95 points above the category average. Speech in noise performance reached 2.7/5, which sits above the category average by 0.59 points, though it remains mixed in absolute terms. This suggests the device handles conversational clarity well in our test scenarios, particularly in quieter environments. The device does face some challenges. Feedback handling scored just 1.7/5, falling 3.02 points below the category average of 4.72/5—a notable weakness compared to other prescription aids in our testing. Music streaming also came in below average at 2.3/5, which is 0.46 points under the category norm. Own-voice comfort scored a mixed 2.9/5, slightly above average. At this price point, several competitors in our database achieved higher overall scores, including the Phonak Sphere Infinio and Oticon Intent. The Lucid Ultra 128 features disposable batteries and supports both iPhone and Android streaming. It may appeal to users who prioritize speech clarity in quiet settings and are less concerned about feedback stability or music streaming fidelity in our standardized tests.

Signia Pure C&G BCT IX Hero
SigniaSoundScore 4.4Grade A

Signia Pure C&G BCT IX

The Signia Pure C&G BCT IX is a premium behind-the-ear prescription hearing aid released in 2025, earning an A grade with a SoundScore of 4.4/5 in our lab testing. Priced at $3,398, it ranks #16 among 39 prescription hearing aids tested. In our standardized testing, this device demonstrates particular strength in own-voice comfort, scoring 3.8/5—a solid result that sits 1.10 points above the category average. This makes it a noteworthy option for users who prioritize natural sound quality when speaking. Speech clarity also performs well, with speech-in-quiet at 3.8/5 (+0.39 points above average) and speech-in-noise at 2.5/5 (+0.43 points above average), though the latter remains mixed in absolute terms despite beating the category benchmark. Feedback handling presents an interesting picture: at 4.2/5, it's strong in absolute terms, though it falls 0.52 points below the category average of 4.72/5. Music streaming scores 2.7/5, essentially matching the category average. The device features rechargeable batteries, iPhone and Android streaming, and hands-free functionality. While the Pure C&G BCT IX delivers solid overall performance, shoppers in this premium price tier should note that competitors like the Phonak Sphere Infinio and Oticon Intent score higher in our testing. Budget-conscious buyers may also find comparable sound quality at lower price points from options like the Rexton Reach R-Li T80 at Costco. This hearing aid is best suited for users who value own-voice naturalness and reliable speech clarity in everyday listening situations.
