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.

Otofonix Helix
The Otofonix Helix is a behind-the-ear amplification product released in 2021, priced at $695. In HearAdvisor's lab testing, it earned a C grade with a SoundScore of 2.6/5, ranking #7 of 8 devices in the Amplification Product category. The Helix demonstrates one clear strength: excellent feedback handling at 5.0/5, which is 0.72 points above the category average. This means users are unlikely to experience whistling or squealing during typical use. However, the device shows significant limitations in other areas. Speech clarity scores are low in both quiet (1.0/5) and noisy (1.0/5) environments, falling below category averages by 1.11 and 0.37 points respectively. Own-voice comfort is notably weak at 0.3/5 in the tuned configuration, measuring 2.34 points below the category average. This suggests users may find their own voice sounds unnatural or boomy. Music streaming capability scored 0.0/5, indicating this device is not suitable for those who want to stream audio content. Consumers in this price range have substantially higher-performing alternatives available. The Sennheiser Conversation Clear Plus scores 4.04/5, while the HearingAssist Micro achieves 3.54/5. Those seeking similar performance at a lower price point might consider the Otofonix Encore or RCA Micro. The Helix may appeal to users who prioritize feedback-free amplification over speech clarity or streaming features, but most shoppers will find better value elsewhere in this category.
