Sony CRE-E10

The Sony CRE-E10 is a mid-priced OTC hearing aid that earns an A grade with a SoundScore of 4.7/5, placing it in the top 3% of the 65 OTC hearing aids tested in our lab. At $998, this visible-in-ear style device delivers performance that competes with the best in its category. Speech performance is a standout strength. Speech in quiet scores a strong 4.3/5, sitting 1.46 points above the category average. Speech in noise reaches a solid 3.3/5, which is 1.77 points above average—a meaningful advantage for conversations in challenging environments. Music streaming quality is another highlight at 4.0/5, exceeding the category average by over 2 points, making it a strong choice for users who value audio fidelity when streaming from their iPhone. The device does have limitations. Own voice comfort scores a low 1.7/5, falling 0.81 points below the category average—users sensitive to the sound of their own voice may find this bothersome. Feedback handling is solid in absolute terms at 3.4/5 but sits 1.14 points below the category average, suggesting slightly less stability margin than many OTC competitors. The CRE-E10 is best suited for users who prioritize speech clarity and streaming quality and are less sensitive to own-voice perception. It has earned HearAdvisor's Expert's Choice Award for three consecutive years (2023–2025), reflecting its consistent strong performance in lab testing.
