Eargo hearing aids are designed to last roughly 3 to 5 years with proper care, similar to most modern hearing aids. The rechargeable batteries inside are typically the limiting factor, as lithium-ion cells gradually lose capacity over hundreds of charge cycles. Beyond battery degradation, the lifespan depends heavily on how well you maintain the devices and protect them from moisture and earwax buildup.
Battery Life Per Charge vs. Overall Lifespan
These are two different questions people often conflate. On a single charge, Eargo devices generally deliver around 16 hours of use, though this varies by model and your volume settings. That per-charge runtime will slowly shrink over the life of the device as the internal battery ages, just like a smartphone battery. After a year or two of daily charging, you may notice sessions getting shorter.
The overall lifespan of the device is harder to pin down because Eargo doesn’t publish a specific number of years. The rechargeable battery cannot be swapped out by the user, so once it degrades enough that a full charge only lasts a few hours, the device is effectively at the end of its useful life. For most users, this point arrives somewhere in the 3 to 5 year range depending on charging habits and environmental conditions.
What the Warranty Covers
Eargo’s warranty length depends on the model. The Eargo 7 and Eargo 7-Rx come with a two-year warranty, while the Eargo SE, SE-Rx, Link by Eargo, and Eargo 6 come with one year. Coverage starts the day you receive the device, not the purchase date.
During the warranty period, you get unlimited repairs and one-time loss or damage coverage per unit. Eargo will also repair or replace devices damaged by earwax buildup up to three times for the same system. A few important exclusions to know: devices bought from unauthorized sellers like eBay have no warranty at all, and damage from chemicals, rough handling, or third-party repairs is not covered.
Water damage rules differ by model. The Eargo 7 line is rated IPX7, meaning it can handle submersion in up to one meter of water for 30 minutes. Its warranty only excludes “prolonged immersion.” The Eargo SE and Link models are less forgiving. Any water immersion at all voids their coverage.
How Water Resistance Affects Durability
If you’re choosing between models, water resistance is a real factor in long-term durability. The Eargo 7’s IPX7 rating means accidental exposure during a shower, a sweaty workout, or getting caught in the rain won’t damage the device. Eargo’s own guidance says to simply take them out and wipe them off if this happens. That level of protection makes the Eargo 7 meaningfully more durable over years of daily use compared to the SE or Link, which lack that same water resistance and can be damaged by any submersion.
Maintenance That Extends Lifespan
The single biggest threat to Eargo’s longevity is earwax. Wax clogs the microphone caps and petal tips, degrading sound quality and potentially damaging internal components. Eargo recommends a daily cleaning routine: brush the mic cap and petal tip with the included cleaning tool to remove wax and debris, then wipe the entire device with the cleaning cloth. They stress doing this even when the devices look clean, since not all buildup is visible.
Two parts need regular replacement. Petal tips and mic caps should both be swapped roughly every month, or sooner if you notice sound quality dropping. Between replacements, you can soak the petal tips in warm soapy water for 3 to 5 minutes, rinse them, and let them dry completely before reattaching. For mic caps, wipe the sound inlet on the device and brush away debris before putting a fresh cap on. Keeping up with these small tasks prevents the kind of wax damage that shortens a device’s life, and earwax-related repairs are limited to three per system even under warranty.
Cost of Ownership After Warranty
Once your warranty expires, repairs come out of pocket, and Eargo devices aren’t designed to be user-serviceable. Because the batteries are sealed inside, there’s no option to pay for a battery swap and extend the device’s life the way you might with traditional hearing aids. If a device fails after the warranty period, you’re likely looking at purchasing a replacement rather than repairing it.
This makes the warranty period a useful benchmark for thinking about your investment. With the Eargo 7’s two-year warranty, you’re guaranteed coverage for roughly the first half of the device’s expected useful life. For the one-year warranty models, you have less of a safety net. Buying directly from Eargo (rather than a third-party marketplace) is essential, since unauthorized purchases void all warranty coverage regardless of the device’s age.
