Choice

Apple AirPods Pro 2
The Apple AirPods Pro 2 is a budget-priced OTC hearing aid that earned an A grade with a SoundScore of 4.0/5 in our lab testing, ranking #18 among 65 OTC hearing aids tested. At $249, it offers hearing assistance through Apple's familiar true-wireless earbud design. In our testing, the AirPods Pro 2 demonstrated strong performance in speech clarity during quiet listening situations, scoring 4.2/5—a full 1.38 points above the OTC category average. Music streaming quality is a standout strength at 4.4/5, exceeding the category average by 2.48 points and delivering strong linear fidelity for phone audio. Feedback handling earned a perfect 5.0/5, indicating excellent stability during movement. Speech understanding in noisy environments scored 2.3/5, which is above the category average by 0.77 points but remains mixed in absolute terms—users in challenging acoustic situations may find performance adequate rather than exceptional. Own-voice comfort is a limitation, scoring 1.9/5 and falling 0.61 points below the category average, which may result in noticeable occlusion effects when speaking. The AirPods Pro 2 is best suited for iPhone users seeking a discreet, multipurpose device that combines solid speech clarity in quieter settings with excellent music streaming. Those who prioritize own-voice naturalness or need stronger noise performance may want to explore alternatives.

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.
