Eargo Launches Eargo 8 with Smart Sound Adjust, Improved Self-fitting System, and Innovative Device Scan

San Jose-based Eargo, known for its tiny and discreet completely-in-canal (CIC) hearing aids, has launched its most advanced over-the-counter (OTC) hearing aid yet: Eargo 8. With upgraded technology that expands the fitting range, enhances environmental adaptability, and introduces a new system that assesses the mechanical wellness of the hearing aid called “Device Scan,” Eargo 8 is designed to address some of the most persistent challenges in hearing care—particularly for users seeking invisible, user-friendly, OTC hearing solutions.

Available for $2,699, the new Eargo 8 will complement the company’s two other products, the Eargo SE ($1,699) and LINK by Eargo ($799). As the new flagship and successor to Eargo 7, Eargo 8 is the first hearing aid launched since Eargo merged with LXE Hearing, a company that includes hearX, the maker of Lexie hearing aids.

Eargo notes that the timing of the launch is significant, as interest in affordable, premium hearing solutions is steadily increasing. Although the OTC hearing aid market is still taking shape, Eargo has addressed several key shortcomings: many consumers are dissatisfied with the limited performance of existing OTC options as well as the lack of meaningful support after purchase—something especially important for first-time users.

Eargo 8: Smarter, More Responsive, and Versatile

Eargo 8 introduces Smart Sound Adjust, an environmental classification system that analyzes noise levels and automatically adapts sound processing without requiring any manual input. Whether entering a noisy restaurant or a quiet office, the device responds dynamically to provide more comfortable and intelligible sound.

“Smart Sound Adjust plays a very important role,” Eargo’s Director of Acoustic Engineering and Clinical Research Ganesh Swaminathan told HearingTracker. “But what’s truly exciting is how all the algorithms—fitting range, feedback cancellation, noise reduction—are working together in harmony. It’s really the entire ecosystem of features that makes Eargo 8 a leap forward.”

The device also includes a redesigned charging case with an extended battery life—up to 14 full recharges, the most in its class. The hearing aids themselves provide up to 16 hours of use per charge, and the case is recharged via USB or a wireless mat. “You can take it on vacation and not worry about recharging for two weeks,” said Eargo VP of Brand and Content Kyong Coleman. “And it’s a sleek black case with the added option of wireless charging, which adds to the convenience.”

Expanding Clinical Utility for Mild to Moderate Loss

One of the standout features of Eargo 8 is its improved fitting range, an area where CICs can often fall short. According to Swaminathan, Eargo 8 consistently meets NAL-NL2 prescription targets for the N3 audiogram [typical for people with mild-to-moderate hearing loss], without triggering feedback or compromising sound quality. This is done via the in-app self-fitting program from Eargo, which adjusts the amplification for the unique hearing needs of the user.

“In our clinical study, we saw that the device could hit N3 targets with precision, and we didn’t have to make sacrifices in other areas,” he said. “To my knowledge, there isn’t another CIC product out there today that achieves this level of performance while still maintaining such a discreet form factor.”

In a study conducted by Eargo, which involved 35 subjects over 16 to 18 weeks using Eargo 8, the vast majority (97%) described a comfortable, feedback-free listening experience. Users also reported significant improvements in Abbreviated Profile of Hearing Aid Benefit (APHAB) scores and reductions in listening fatigue, as measured by the Vanderbilt Fatigue Scale (VFS). Under self-guided conditions, most participants reported wearing their devices 5-7 days a week, often for 8 hours or more per day—suggesting both meaningful and seamless integration into their daily lives, according to Eargo.

“These benefits were not just statistical; they were sustained across the full study period,” said Swaminathan. “Participants wore the devices for 8 to 10 hours daily and still reported high comfort and satisfaction.”

“We’re incredibly proud to unveil Eargo 8—this isn’t just another hearing aid, it’s a leap forward in technology, user experience, and accessibility,” said LXE Hearing Chief Technology Officer Tim Trine in a press statement. “With Eargo 8, we’ve achieved an extraordinary breakthrough in sound quality and user experience that redefines what OTC hearing aids should be. We’ve done the research, pushed the technology, and listened to our customers to deliver a smarter, sleeker, and more accessible model.”

Device Scan: A New System for Wax Detection

CIC hearing aids are notoriously susceptible to wax intrusion, which can clog the receiver ports, muffling and degrading sound quality, and sometimes necessitate repairs. Eargo 8 offers an innovative solution to this problem with its new Device Scan feature—a patented wellness-check system that utilizes acoustic signatures to identify blockages.

Using microphones placed in both the hearing aid and the charger, the system compares sound energy to baseline values, identifying when wax has begun to compromise sound quality. Users can initiate a scan through the Eargo mobile app and receive notifications if a cleaning is needed.

“This is a big deal for CICs,” said Swaminathan. “We’re using the physics of sound energy in a very smart way to help maintain long-term performance and reduce support issues. The charger itself plays a critical role—it’s no longer just for power, it’s an acoustic analyzer.”

Enhanced Sound, Especially for Music

In addition to enhancing speech intelligibility, Eargo 8 also improves music enjoyment—a common weakness in many hearing aids. By carefully balancing compression, feedback cancellation, and noise reduction, Eargo has developed a music program that scored higher on the Hearing Aid Speech Quality Index than standard programs across various music genres.

“We didn’t just tweak a few settings,” said Swaminathan. “We developed a music-specific offset that harmonizes all the signal processing components. In blinded comparisons, users consistently preferred the music program.”

Pricing, Support, and Future Direction

Eargo 8 replaces Eargo 7 as the company’s flagship product. The company says it offers more features at a better starting price, while maintaining its premium positioning in the OTC market. The rest of Eargo’s portfolio—including LINK by Eargo and Eargo SE—remains available. Eargo 7 will be gradually phased out, but it continues to receive full support.

“Support has always been central to what we offer,” said Coleman. “We think the post-purchase experience is critical, especially for first-time users navigating OTC hearing aids. With Eargo 8, you still get best-in-class assistance through tutorials, live experts, and proactive device orientation.”

The launch also comes on the heels of the merger between Eargo and hearX, parent company of Lexie Hearing. While Lexie primarily focuses on receiver-in-canal (RIC) OTC devices, Eargo’s CICs expand the combined company’s form factor offerings under the new umbrella of LXE Hearing.

“With the launch of Eargo 8, we pushed the boundaries of what is possible for such a small, compact and nearly invisible design. We remain committed to raising the bar for hearing wellness while delivering incredible value for our customers,” said LXE CEO Nic Klopper in the press statement. “Traditional prescription hearing aids and other nearly invisible options can be prohibitively expensive for consumers, costing upwards of $7,000. This puts quality, comfort, and support out of reach for many. Eargo was founded on a mission to battle this and improve access and affordability for more people. And with Eargo 8, we’ve packed more advancements than ever in our OTC device and are proud to have successfully reduced our pricing to make premium hearing more accessible than ever.”

In a recent interview, Klopper told HearingTracker that he was excited about Eargo’s product launches, which he views as “extremely groundbreaking.” Combined with $100 million in new capital from the recent partnership, innovative products, a strong platform, and an experienced team, LXE Hearing is poised for exceptional growth.

“It’s a great fit,” agrees Coleman, noting in particular the two companies’ traditional emphasis on telecare support. “Both companies have been pursuing accessibility and quality from different angles and form factors. Now, we’ve joined forces to offer a broader, more comprehensive set of solutions.”

Due to its small size, the Eargo 8 is a non-wireless device that does not support audio streaming for music, podcasts, or phone calls. However, it does utilize an app which allows you to personalize settings with Sound Match, as well as control the volume, treble, and bass within each program, as well as adjust other functions.

With Eargo 8, the company has made a compelling case for how innovation in miniaturized hearing technology can drive real-world clinical benefits—without compromising discretion or usability. From its expanded fitting range and superior feedback management to the one-of-a-kind Device Scan system, Eargo 8 stands out in a crowded over-the-counter (OTC) field.

“It’s not just one or two new things in Eargo 8, but everything working together inside this tiny form factor,” said Swaminathan. “It’s addressing stigma, comfort, sound quality, and support—all in one ecosystem. That's what makes Eargo 8 really special.”
