How We Test

The Eargo 6 is a premium-priced OTC hearing aid ($2,250) featuring an invisible-in-ear design with rechargeable batteries. In HearAdvisor's lab testing, it earned a B grade with a SoundScore of 3.1/5, placing it in the top 49% of OTC hearing aids tested.

This device shows mixed performance across key metrics. Speech clarity in quiet environments scores 2.9/5, which is 0.26 points above the category average—though still only mixed in absolute terms. Own-voice comfort also performs above the category average by 0.41 points at 2.9/5, suggesting the Eargo 6 handles the common complaint of hearing your own voice somewhat better than typical OTC devices.

However, the Eargo 6 struggles in several areas. Speech in noise scores just 0.6/5, falling 0.53 points below the category average, which may limit its usefulness in challenging listening environments like restaurants or group conversations. Music streaming is notably weak at 0.0/5, scoring 1.93 points below average—those who prioritize phone audio streaming should look elsewhere. Feedback handling, while solid at 3.3/5, still falls 1.23 points below the category average.

At this price point, consumers may want to consider alternatives. Several OTC devices at lower price points deliver similar or better sound performance, including the Sony CRE-C10 and Olive Union Air. The Eargo 6 is best suited for users who prioritize the invisible form factor and reasonable own-voice comfort over streaming capabilities and performance in noisy settings.

Fit Conditions

Eargo 6 Initial and Tuned Fit Summaries

Below you can view separate performance summaries for the Eargo 6 in both its Initial factory configuration and after professional tuning adjustments. Each summary presents the measured outcomes specific to that fit condition.

Lab Test Summary

In initial fit testing with sleeve closed ear coupling, the Eargo 6 achieved a normalized score of 3.1/5. Speech in quiet measured 2.5/5 while speech in noise scored 0.7/5. Feedback handling performed well at 4.4/5, and own-voice comfort scored 2.9/5. Music streaming scored 0.0/5, indicating this configuration does not support quality audio streaming. The initial fit delivers reasonable feedback control out of the box but limited benefit for speech understanding in challenging acoustic environments.

What is HearAdvisor's Initial Fit?

The Initial Fit approximates the most likely settings and eartips for a typical moderate hearing loss. Results are measured across the same 72 acoustic scenes in our custom-built lab, then scored on a 5-star scale using an auditory model.
