OliveSoundScore 3.4Grade B

Olive Union Max

The Olive Union Max is a behind-the-ear OTC hearing aid priced at $190, earning a B grade with a SoundScore of 3.4/5 in HearAdvisor's lab testing. This budget-friendly device ranks #41 of 65 OTC hearing aids tested. In our lab testing, the Max shows a distinctive performance profile with clear strengths and limitations. Music streaming stands out with a strong 4.0/5 score, measuring 2.08 points above the OTC category average—making it one of the better choices for audio entertainment. Feedback handling is excellent at 5.0/5, meaning the device maintains stability without whistling during typical daily activities. However, speech performance presents challenges. Speech in quiet scores a mixed 2.6/5, falling 0.21 points below the category average, while speech in noise is low at 1.0/5, measuring 0.48 points below average. Own-voice comfort also scores low at 1.6/5, sitting 0.91 points below the category average—users may notice their own voice sounds unnatural or hollow. The Olive Union Max is best suited for budget-conscious consumers who prioritize music and media streaming over demanding listening environments. Those who frequently need to follow conversations in noisy settings like restaurants or social gatherings may find the speech-in-noise limitations frustrating. For basic amplification in quieter environments with excellent streaming quality at an accessible price point, the Max offers reasonable value despite its speech performance trade-offs.

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.
