SennheiserSoundScore 4.4Grade A

Sennheiser All Day Clear

The Sennheiser All Day Clear is a mid-priced OTC hearing aid that earns an A grade with a SoundScore of 4.4/5, placing it in the top 8% of all OTC hearing aids tested in our lab. At $949, this behind-the-ear device delivers strong overall performance that stands out in a crowded category. In our testing, the All Day Clear excels at speech clarity in quiet environments, scoring 4.0/5—a full 1.25 points above the OTC category average. Music streaming is another highlight, with a solid 3.3/5 score that's 1.38 points above average, making it one of the better choices for listeners who want quality audio beyond speech. Feedback handling is excellent at 5.0/5, meaning users shouldn't experience whistling issues during normal use. Speech in noise presents a more nuanced picture. At 1.9/5, the score sits 0.39 points above the category average, but remains low in absolute terms—a common challenge across OTC devices. Own-voice comfort scores at 2.5/5, essentially matching the category average. The Sennheiser All Day Clear is well-suited for users who prioritize clear speech understanding in everyday quiet-to-moderate listening situations and value high-quality audio streaming. Those frequently in noisy environments may want to manage expectations, though this limitation is shared across most OTC alternatives.

SigniaSoundScore 4.1Grade A

Signia Pure C&G IX

The Signia Pure C&G IX is a premium behind-the-ear prescription hearing aid released in 2023, currently available at $3,298. In HearAdvisor's lab testing, it earned an A grade with a SoundScore of 4.1/5, ranking #22 among 39 prescription hearing aids tested. This device demonstrates notable strengths in speech clarity and feedback control. Speech in quiet scored 4.0/5, which is 0.57 points above the category average—a meaningful advantage for everyday conversations. Feedback handling achieved a perfect 5.0/5, sitting 0.28 points above the already-high category average of 4.72/5. Own-voice comfort also performed well at 3.2/5, exceeding the category average by 0.50 points. Speech in noise presents a more mixed picture. While the 2.2/5 score is technically above the category average by 0.10 points, it remains modest in absolute terms—something to consider if challenging listening environments are a priority. Music streaming scored a solid 3.0/5, sitting 0.24 points above average. The Pure C&G IX features rechargeable batteries and supports streaming to both iPhone and Android devices, including hands-free calling. At this premium price point, competitors like the Phonak Sphere Infinio (4.98/5) and Oticon Intent (4.83/5) achieve higher overall scores. This device may suit those who prioritize clear speech in quieter settings and excellent feedback stability, though buyers seeking stronger noise performance may want to compare alternatives.
