Buying a hearing aid starts with one key decision: whether your hearing loss is mild enough for an over-the-counter device or significant enough to need a prescription one. Since October 2022, the FDA has allowed adults 18 and older with perceived mild to moderate hearing loss to buy OTC hearing aids directly from stores or online retailers, no exam or prescription required. For anything beyond moderate loss, or for anyone under 18, you’ll need to go through a licensed hearing professional.
Know Your Level of Hearing Loss First
Hearing loss is measured in decibels (dB), and the severity determines which devices will actually help you. The American Speech-Language-Hearing Association classifies it this way: mild is 26 to 40 dB, moderate is 41 to 55 dB, severe is 71 to 90 dB, and profound is 91 dB or higher. If you’re struggling to follow conversations in noisy restaurants or turning the TV up louder than others prefer, that often falls in the mild to moderate range. If you have trouble hearing people even in quiet rooms, or you can’t follow speech without reading lips, you’re likely dealing with severe or profound loss.
You don’t technically need a hearing test to buy an OTC device, but getting one is still smart. An audiogram maps your hearing ability across different frequencies, showing exactly where your hearing drops off. Without that information, you’re guessing at what you need. Many audiologists offer standalone hearing evaluations, and some OTC brands include app-based hearing assessments to help you get started.
OTC vs. Prescription Hearing Aids
OTC hearing aids are designed for adults with mild to moderate hearing loss. You can pick them up at pharmacies, electronics stores, or online without a medical exam or fitting appointment. They’re limited in maximum output by FDA regulation, which means they won’t be powerful enough if your loss is more severe. Prices for OTC models typically start around $200 to $800 per pair, making them significantly cheaper than prescription options.
Prescription hearing aids are available through audiologists or hearing instrument specialists and can treat all levels of hearing loss. These devices get programmed to your specific audiogram, physically adjusted to your ear, and verified with measurements that confirm sound is being delivered correctly. The tradeoff is cost and time: you’ll need appointments, and the devices themselves are more expensive. But for moderate to profound loss, prescription aids are the only category that can adequately treat the problem.
Choosing a Style
Hearing aids come in several physical styles, and the right one depends on your degree of hearing loss, your comfort preferences, and how visible you want the device to be.
- Behind-the-ear (BTE): The largest style, with all components housed in a case that hooks over your ear. Best for moderate to profound hearing loss. Durable and easy to handle.
- Receiver-in-canal (RIC): Similar to BTE but smaller, with a tiny speaker that sits inside your ear canal connected by a thin wire. Covers mild to severe loss and is the most popular style sold today.
- In-the-ear (ITE): Fills the outer bowl of your ear. Works for mild to severe loss and is easier to insert than smaller models.
- In-the-canal (ITC) and completely-in-canal (CIC): Smaller, more discreet options that sit partially or fully inside the ear canal. Best suited for mild to moderate loss. Smaller batteries mean shorter runtime.
- Invisible-in-canal (IIC): The smallest available, sitting deep in the ear canal where others can’t see it. Only works for mild to moderate loss and requires a normal-sized ear canal.
Smaller styles are more cosmetically appealing, but they sacrifice battery life, feature options, and power. If you have significant hearing loss, a BTE or RIC will serve you far better than trying to squeeze into a CIC for appearance reasons.
Features Worth Paying For
Modern hearing aids come packed with technology, but a few features stand out as genuinely useful rather than marketing fluff.
Bluetooth connectivity lets your hearing aids receive audio directly from your phone, TV, or computer. This makes a real difference for phone calls and streaming, because the sound bypasses background noise entirely and goes straight into your ears. Both devices need Bluetooth enabled and must be paired, and the connection works within roughly 30 feet.
A telecoil (or T-coil) picks up signals from hearing loop systems installed in many theaters, airports, churches, and public buildings. Unlike Bluetooth, which connects one device to one person, a telecoil lets you tap into a room-wide loop that serves everyone in the space. Having both Bluetooth and telecoil gives you the widest range of direct-sound options. Some hearing aids let you toggle between a telecoil-only mode that blocks background noise and a mixed mode that lets some ambient sound through.
Rechargeable batteries are now standard on most mid-range and premium models. You drop the aids into a charging case at night and they’re ready in the morning. The convenience is real, but rechargeable battery capacity does decrease after two to three years, which may mean shorter runtime as the devices age. Disposable battery models (using size 312 batteries, for example) typically last four to nine days per set depending on usage and streaming habits. Neither option is clearly superior; it comes down to whether you prefer nightly charging or occasional battery swaps.
Where to Buy
You have three main channels, each with distinct tradeoffs in price, selection, and service.
Private Audiology Clinics
Audiologists in private practice offer the widest selection of brands and the most personalized service. They typically spend more time per appointment, perform comprehensive hearing evaluations, and use real-ear measurements to verify your devices are calibrated correctly. Real-ear measurement involves placing a tiny microphone in your ear canal alongside the hearing aid to confirm the amplification matches your hearing loss profile at each frequency. Not every provider does this, so it’s worth asking. The downside: follow-up visits for adjustments and cleanings may be billed separately, and the overall cost tends to be highest here.
Big-Box Retailers
Costco is the most prominent example. Their hearing aid centers carry reputable brands like Phonak and ReSound alongside their in-house Kirkland brand, which consistently gets strong reviews. Prices are typically lower than private clinics, and the package usually includes free follow-up appointments and cleanings. Costco also offers a 180-day return window, which is exceptionally generous. The limitation is less one-on-one time with the hearing specialist and a somewhat narrower product selection compared to a private audiologist.
Online and OTC Retailers
If your hearing loss is mild to moderate, OTC devices purchased online or from a drugstore can be a reasonable starting point at a fraction of the cost. The tradeoff is that no professional is fitting or verifying the device for you, so results depend heavily on how well the product matches your specific loss pattern.
What Hearing Aids Actually Cost
A single prescription hearing aid typically costs between $1,500 and $4,350, and most people need two. That price usually includes the device, the fitting appointment, and some level of follow-up care (a “bundled” model). Broken down by technology tier, you’re looking at roughly $83 per month for essential-level technology up to $231 per month for top-of-the-line devices, assuming a standard replacement cycle.
Original Medicare (Parts A and B) does not cover hearing aids or the exams needed to fit them. You pay the full cost out of pocket. Some Medicare Advantage plans (Part C) do include hearing benefits, so check your specific plan. Private insurance varies widely. Some employers offer a hearing aid allowance every few years, while many plans cover nothing at all.
Several strategies can reduce costs. Costco’s bundled pricing is consistently among the lowest for prescription-quality devices. Many audiologists offer financing plans. Some states have vocational rehabilitation programs that help cover hearing aids for working adults. And OTC aids, while limited in power, can work well for mild loss at a much lower price point.
The Fitting and Adjustment Process
If you go the prescription route, expect the process to take at least two appointments. The first is a comprehensive hearing evaluation that produces your audiogram. The second is the fitting itself, where your audiologist programs the hearing aid based on your audiogram results, physically adjusts it for comfort, and walks you through daily use and maintenance.
The initial settings rarely feel perfect. Your brain needs time to readjust to sounds it hasn’t been processing fully, and certain environments will reveal where the programming needs tweaking. Most people return for one or more follow-up adjustments in the first few months. This is normal and expected. Fine-tuning is an ongoing process, not a sign that something is wrong.
Trial Periods and Returns
Most states require hearing aid sellers to offer a trial period, though the length and terms vary. Connecticut, for example, mandates a 30-day trial with the right to return devices for a refund minus a cancellation fee of up to 12%. Many sellers offer longer windows voluntarily. Costco’s 180-day policy is the industry benchmark for generous returns.
Before you buy from any provider, ask three questions: How long is the trial period? Is there a restocking or cancellation fee? And what follow-up appointments are included in the purchase price? Getting clear answers upfront protects you from surprises and gives you a genuine opportunity to evaluate whether the devices work in your real life, not just in the quiet of a fitting room.
