Speech in noise performance is more modest at 2.3/5, which is above the category average by 0.79 points but mixed in absolute terms. This pattern suggests the device handles everyday conversations well while challenging listening situations may still present difficulty. Music streaming is a particular strength, scoring 3.6/5 and exceeding the category average by a substantial 1.68 points. Feedback handling is excellent at 4.5/5, virtually matching the category average. Own-voice comfort scores a solid 3.0/5, which is 0.49 points above average for OTC devices.

Consumers seeking alternatives in this price range may also consider the similarly-priced Lucid Tala, while the lower-priced Lexie B3 offers competitive performance for those with tighter budgets.

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.
