Eargo launched the Eargo 8 in May 2025, its latest flagship OTC hearing aid promising significant advancements in self-fitting hearing technology and user convenience. With a price of $2,699 (pair and charger), the device is marketed toward adults experiencing mild to moderate hearing loss, aiming to balance advanced features, ease of use, and affordability.

The Eargo 8 introduces several noteworthy features, according to company claims, including "Smart Sound Adjust," which automatically adapts to changing sound environments without manual intervention. The new "Device Scan" feature—patented exclusively to Eargo—allows users to perform routine checks on device health, potentially helping extend device lifespan through timely maintenance.

Additionally, Eargo highlights improvements in audio fidelity with its "Superior HD Sound" and "Premium Environmental Adaptation," which the company claims enhances the quality of conversations, music, TV dialogue, and phone calls. The Eargo 8 also expands its fitting range, covering a broader spectrum of hearing loss, and incorporates robust IP68 dust and water resistance.

Battery life remains a significant selling point, with the Eargo 8 claiming up to 16 hours per charge and a charging case providing up to two weeks (14 recharges) of power—currently one of the longest available in the OTC category. The device also ships with a generous two-year warranty, a 45-day risk-free trial, and lifetime customer support from Eargo's team of experienced hearing aid professionals.

Eargo also offers a pared-down version of this hearing aid with its Eargo SE model. You can think of this as the "economy" version of Eargo 8, as it lacks Smart Sound Adjust, and it carries a lower IP54 water and dust resistance rating versus Eargo 8’s IP68.

Eargo claims their new rechargeable hearing aids can run for 2 weeks away from a power source.

Eargo 7 vs Eargo 8

Compared to its predecessor, Eargo 7, the new Eargo 8 claims several significant upgrades. Most notably, Eargo 8 introduces automatic sound environment adjustments with "Smart Sound Adjust," potentially improving real-time adaptation to noisy surroundings. It also adds the patented "Device Scan" feature, aiming to ensure device longevity through proactive maintenance checks.

Eargo claims their new "Device Scan" feature can tell you if your speaker or microphones have technical issues—both are common problems for in-the-ear style hearing aids due to wax and moisture.

While both devices emphasize discretion with their virtually invisible design, the Eargo 8 expands the fitting range for a broader spectrum of mild-to-moderate hearing loss and offers improved environmental sound processing, particularly for music and phone calls. However, like the Eargo 7, the latest model still does not support Bluetooth audio streaming, relying instead on Eargo's proprietary wireless control system.
