OtofonixSoundScore 2.7Grade C

Otofonix Groove

The Otofonix Groove is a behind-the-ear prescription hearing aid priced at $795, earning a C grade with a SoundScore of 2.7/5 in our lab testing. This rechargeable BTE ranks #38 of 39 devices in the prescription hearing aid category, placing it in the bottom 5% of its class. In our testing, the Groove demonstrated excellent feedback handling at 5.0/5, scoring 0.28 points above the category average. This represents a genuine strength, with the device maintaining stability during our standardized challenge motions. However, speech performance was significantly limited, with speech in quiet scoring 1.0/5 (2.40 points below the category average of 3.40) and speech in noise also at 1.0/5 (1.11 points below average). Music streaming was not functional in our tests, scoring 0.0/5 against a category average of 2.76. Own-voice comfort also fell well below typical prescription hearing aid performance at 0.4/5, which is 2.30 points below the category average. At this price point, several lower-cost alternatives delivered stronger overall performance in our testing. Consumers seeking value in the prescription category may want to explore other options, though those requiring robust feedback control in a rechargeable BTE format may find the Groove's stability noteworthy despite its other limitations.

ZeppSoundScore 3.9Grade B

Zepp Clarity One

The Zepp Clarity One is a mid-priced OTC hearing aid with an invisible-in-ear design, priced at $699. In HearAdvisor's lab testing, it earned a B grade with a SoundScore of 3.9/5, ranking #23 among 65 OTC hearing aids tested—placing it in the top 34% of the category. This device demonstrates notable strengths in speech clarity during quiet environments, scoring 3.7/5—nearly a full point above the category average. Own-voice comfort is another highlight at 3.8/5, measuring 1.29 points above average, which suggests reduced occlusion effects that many users find bothersome with in-ear devices. Feedback handling is excellent at 5.0/5 in the tuned configuration. However, the Clarity One has significant limitations. Speech understanding in noisy environments scores just 1.4/5, slightly below the category average. Most notably, music streaming scored 0.0/5—nearly 2 points below the category average—indicating this device does not support audio streaming functionality, a feature some competitors in this price range offer. The Zepp Clarity One is best suited for users who prioritize clear speech in quieter settings and natural own-voice quality, and who do not need music or media streaming capabilities. Those seeking better noise performance or streaming features should consider alternatives, including options like the Olive Union Air, which offers similar overall sound quality at a lower price point.
