The FDA's over-the-counter rule put hearing aids on the open market, and the Mercury is the top model in LINNER's curated hearing-aid collection: a rechargeable mini-RIC pair with 16-channel processing and app tuning at $229.99.
Since the FDA's over-the-counter hearing aid category took effect in October 2022, adults have been able to buy hearing aids off the shelf, no prescription or audiologist visit required. LINNER, a brand launched in 2021 by Epha Medtech, a Santa Clara company founded in 2016, builds for this category, and the Mercury is the top model in the brand's curated hearing-aid collection: a receiver-in-canal (mini-RIC) pair in beige gold at $229.99 against a $299.99 list price. (A step-up Clarity model sells for $299.99 on the wider site, outside the main lineup.)
The spec sheet is solid for the price band. Sound processing runs through 16 WDRC channels (wide dynamic range compression, the same basic architecture prescription aids use to amplify soft sounds more than loud ones), with what the brand calls advanced noise reduction and 3 customizable listening modes. A short press of the rocker steps through 9 volume levels. The rechargeable cells run a brand-claimed 20 hours per charge, the USB-C case holds 3 more full charges, and fitting is self-serve through the LINNER HA app, which adjusts amplification to your hearing profile. LINNER backs the purchase with a 45-day free trial and a 1-year warranty, and the listing is marked FSA and HSA eligible.
Where it gives ground: the Mercury does not stream Bluetooth audio, and that is not us guessing, the brand's own product FAQ states it plainly. Calls, TV, and music stay on your phone or separate hardware. There is one color and one variant. And note a category wrinkle: LINNER's own product page pitches the Mercury's fitting range as moderate to severe in one answer and mild to severe in another, while the FDA defines the OTC category around perceived mild to moderate loss in adults 18 and up. Treat that fitting-range language as a brand claim, and know that self-fitting through an app is the trade you make for skipping the clinic and its four-figure price tags.
At $229.99 with a 45-day return window, the cost of finding out whether an OTC device suits you is about as low as this category gets.

LINNER Mercury mini-RIC - buyer FAQ
How much do the LINNER Mercury hearing aids cost?
The Mercury mini-RIC pair sells for $229.99 against a $299.99 list price, verified August 2026 on linnerlife.com. The purchase includes a 45-day free trial and a 1-year warranty, and the listing is marked FSA and HSA eligible, so pre-tax health dollars can cover it.
Are the LINNER Mercury hearing aids FDA over-the-counter devices?
They sell under the FDA over-the-counter hearing aid category, which since October 2022 covers adults 18 and up with perceived mild to moderate hearing loss. LINNER pitches a wider fitting range on its own page, in one answer moderate to severe, in another mild to severe, so treat the fitting-range language as a brand claim. Fitting is self-serve through the LINNER HA app.
Do the LINNER Mercury hearing aids stream Bluetooth audio?
No, and the brand FAQ states it plainly. The app connection is for fitting and tuning only: 16 WDRC processing channels, 3 listening modes, and 9 volume levels adjusted from the rocker. Calls, TV, and music stay on your phone or separate hardware, which is the biggest trade-off at this $229.99 price.
How long does the battery last on the LINNER Mercury?
LINNER claims 20 hours per charge, with a USB-C charging case that holds 3 additional full charges and a 2-hour recharge time. That is a claimed full day of wear per charge and roughly four days of use before the case itself needs power.
Can I return LINNER hearing aids if they do not work for me?
The product page advertises a 45-day free trial alongside a 1-year warranty, verified August 2026. Forty-five days covers the adjustment period audiologists usually recommend for new hearing aid users, so you can judge them against real daily use, not a showroom minute.
