Quick Answer: Hearing aid trial periods range from 30 days (the minimum required by many states for clinic-fitted aids) up to 180 days at Costco. Among direct-to-consumer and OTC brands, Jabra Enhance Select offers a 100-day risk-free trial — the longest of any major OTC seller — while Eargo, Lexie and MDHearing each offer 45 days. State-mandated trials for prescription hearing aids are shorter and sometimes come with a cancellation fee: Connecticut law permits sellers to keep up to 12% of the purchase price even during the trial window. Before buying anywhere, confirm the exact trial length, whether shipping is refunded, and whether the window shrinks if you buy through a third-party marketplace instead of direct.

Hearing aids are one of the few health purchases where “try before you buy” is written into law — but the length of that trial varies by a factor of six depending on where and how you buy. A 30-day state minimum and a 180-day Costco return window are not the same product decision, and most buyers never compare the two before paying.

  • If a long, no-questions-asked trial matters most to you, Jabra Enhance Select's 100-day window gives you roughly triple the trial length of most competing OTC brands.
  • If you're buying through Costco, factor in the 180-day return window alongside the 3-year repair warranty — it's the most forgiving purchase in the category.
  • Whichever brand you choose, keep the original packaging and all accessories until the trial window closes; incomplete returns can forfeit part of the refund.

Trial periods this long mean you’ll likely need replacement domes or wax guards before you’ve even decided whether to keep the aids — try Amazon Prime free for 30 days to get accessories in two days instead of waiting on a slow reorder.

Why the trial period matters more than the price tag

A hearing aid that fits perfectly in the store often doesn’t perform the same in a noisy restaurant, on a phone call, or after a week of all-day wear. That’s precisely why these laws and brand policies exist — hearing aid fit is something you can only really evaluate by living with the device, not by trying it on for ten minutes. A shorter trial period puts pressure on you to decide fast; a longer one lets real-world use surface problems (feedback, discomfort, poor speech clarity in noise) before your money is locked in.

This is also why trial length is a legitimate factor in choosing a brand, not just a fallback if something goes wrong. If you’ve never worn a hearing aid before, or your hearing loss is asymmetric or noise-dependent, a 100-day or 180-day trial gives you multiple seasons and social situations to test the fit. If you’re replacing a device you already know works well for you, a 30–45 day trial is plenty.

A quick health note

Trial periods are a purchasing safeguard, not a substitute for medical evaluation. If your hearing loss is sudden, one-sided, accompanied by pain or drainage, or your tinnitus pulses or is one-sided, see a hearing professional before trying any device, OTC or prescription. Over-the-counter hearing aids are intended for adults 18 and over with perceived mild-to-moderate hearing loss in both ears.

The bottom line

Match the trial length to your confidence in the fit, not just the price. State law guarantees a 30–45 day floor for clinic-fitted hearing aids, but the real spread runs much wider: Jabra Enhance Select’s 100-day risk-free trial and Costco’s 180-day return window both give you far more time to live with a device than the legal minimum, while Eargo, Lexie, MDHearing and ELEHEAR’s direct-purchase channel cluster around 45 days. Whatever you choose, confirm the number in writing, buy through the channel that keeps the longer window intact, and compare current OTC pricing on Amazon before your trial clock starts.
