Cearvol Diamond X1 vs Oticon Real
Side-by-side HearAdvisor lab results with SoundGrades, expert pick badges, and the same visualizations we use in product reviews.

Cearvol Diamond X1
The Cearvol Diamond X1 is a budget-priced OTC hearing aid that earned a B grade with a SoundScore of 3.7/5 in our lab testing, placing it in the top 45% of OTC devices. At $199, it represents an accessible entry point for those exploring hearing amplification. The Diamond X1's standout performance is in music streaming, scoring 4.1/5—a strong result that sits 2.18 points above the OTC category average. This makes it notably capable for users who prioritize audio entertainment through their hearing devices. Feedback handling is also excellent at 4.5/5, meaning users should experience minimal whistling during normal use. However, speech performance presents limitations. Speech in quiet scores a mixed 2.8/5, and speech in noise registers at 1.7/5. While both metrics technically sit above category averages (+0.03 and +0.22 points respectively), they remain low in absolute terms—important context for anyone prioritizing conversation clarity. Own-voice comfort is another weakness, scoring 1.7/5, which is 0.81 points below the category average and may affect how natural users sound to themselves. The Diamond X1 is best suited for budget-conscious consumers who value music streaming quality and aren't heavily reliant on challenging listening environments. Those who prioritize speech understanding in noise or natural own-voice perception may want to consider alternatives in this price range, such as the higher-scoring Elehear Beyond or Apple AirPods Pro 2.
Choice
Oticon Real
The Oticon Real is a premium prescription behind-the-ear hearing aid released in 2023, priced at $4,798. In HearAdvisor's lab testing, it earned an A grade with a SoundScore of 4.7/5, placing it in the top 10% of the 39 prescription hearing aids tested and ranking #5 in its category. Speech performance is a clear strength for the Oticon Real. Speech in quiet scored a strong 4.0/5, sitting 0.64 points above the category average. Speech in noise measured 2.9/5—above the category average by 0.82 points, though still mixed in absolute terms. This combination makes it a solid choice for listeners prioritizing conversation clarity across different environments. Feedback handling scored a strong 4.0/5 in absolute terms, though this falls 0.72 points below the category average of 4.72/5. Own voice comfort scored 2.4/5, which is 0.30 points below the category average—a potential consideration for those sensitive to how their own voice sounds. Music streaming performance was mixed at 2.8/5, essentially matching the category average. The Oticon Real is a two-time Expert's Choice Award winner (2023, 2024) and offers flexible power options with both rechargeable and disposable batteries. It supports iPhone and Android streaming along with hands-free calling. Within its premium price tier, it faces strong competition from devices like the Phonak Sphere Infinio and Oticon Intent, but remains a compelling option for users who prioritize speech intelligibility and are willing to invest in top-tier technology.
