MDHearing sells low-cost over-the-counter hearing aids direct and on Amazon. The VOLT 4 is its behind-the-ear model: rechargeable, button-controlled, with no app needed.
MDHearing makes some of the most affordable rechargeable hearing aids you can buy without seeing an audiologist, and the VOLT 4 is the model we recommend most older buyers start with. It sits behind the ear, which makes it far easier to handle with stiff fingers than a tiny in-canal aid. It charges overnight and runs about 20 hours. Everything is controlled with two buttons, so there is no app or Bluetooth pairing to wrestle with.
Be clear about the trade-offs. MDHearing aids are basic. Independent lab testing by HearAdvisor gave the tiny NEO XS a C grade and found little speech benefit in noise. They are only for mild-to-moderate hearing loss. Their “sale” pricing is permanent enough that reviewers have called it misleading. If you want the best sound an OTC aid can deliver, our top pick in the best hearing aids for seniors guide scores far higher in independent tests.
For a simple, low-cost, no-phone hearing aid backed by a 45-day trial, the VOLT 4 is a sensible place to start.

Buy it if…

- You do not want an app, Bluetooth or a smartphone involved
- You find small in-ear aids fiddly to insert and remove
- You want to try hearing aids at low cost before considering clinic-fitted ones
Look elsewhere if…
- You have severe hearing loss, sudden loss, pain, drainage or loss in one ear only: see a doctor first
- You want phone calls and TV streamed into your ears: look at Bluetooth models in our hearing aid guide
- You want the best sound in noisy restaurants: higher-graded OTC aids do better in independent tests
- You want an aid tuned to your own hearing test: choose a self-fitting OTC aid or see an audiologist
Who MDHearing is
MDHearing (formerly MDHearingAid) was founded in Chicago by Dr. Sreekant Cherukuri, a board-certified ear, nose and throat surgeon. The idea was to sell hearing aids directly to consumers at a fraction of clinic prices. Since the FDA created an over-the-counter hearing aid category in October 2022, MDHearing’s aids have been sold as OTC devices for adults with perceived mild-to-moderate hearing loss.
You buy them online, from MDHearing or on Amazon, with no hearing test or prescription required. You fit them yourself using silicone domes in several sizes. Support is by phone, and MDHearing sells an optional paid VIP Care plan for video help from a licensed professional.
Every current MDHearing model compared
MDHearing’s range changes often and its model names are confusing. This is the current line-up as reported by NCOA in September 2026, with prices per pair from MDHearing. Prices on Amazon can differ, and MDHearing frequently advertises these as “sale” prices.
Which to pick: for most older buyers, the VOLT 4. Behind-the-ear aids are easier to handle and see, and it has the longest battery life. Choose the NEO XS only if invisibility matters more than ease of handling, and read the lab results below first. Choose the VOLT MAX only if you want app control.
| Model | Style | Battery | App / Bluetooth | Price |
|---|---|---|---|---|
| VOLT 4 | Behind the ear | ~20 hours | No | ~$397 |
| AIR | Behind the ear | ~16 hours | No | ~$297 |
| VOLT MAX 2 | Behind the ear | ~15 hours | Yes | ~$597 |
| NEO | In the canal | ~17 hours | No | ~$297 |
| NEO XS | Completely in the canal | ~18 hours | No | ~$297–$397 |
| NEO XS PRO | Completely in the canal | Not stated | Yes | ~$597 |
The VOLT 4 in detail
The VOLT 4 is a behind-the-ear (BTE) aid: the electronics sit in a small curved case behind the ear, and a thin tube carries sound to a soft dome in the ear canal. That makes it the easiest MDHearing model to pick up, put on and take off, and it sits comfortably with glasses.
- Battery: rechargeable, about 20 hours per charge. Put it in its charging case overnight. The Amazon listing describes a portable charging case.
- Controls: two buttons on each aid, for volume and for switching between four programs: Quiet, Social, Noisy and Restaurant.
- Sound features: dual microphones, background noise reduction and feedback cancellation, which reduces whistling.
- No app, no Bluetooth: nothing to pair, update or lose. The flip side is no streaming of phone calls or TV.
CompareHearingAids called it plain, with “no standout features,” and that is fair. For many older buyers, plain is the point.
Are MDHearing aids any good? What independent tests found
Most hearing aid reviews describe the product. HearAdvisor, an independent lab, actually measures it, using a manikin in realistic sound environments. Its results for the NEO XS were poor: a SoundGrade C (2.5 out of 5), with little speech benefit in quiet rooms and none in noise, although feedback control scored full marks. HearingTracker’s reviewer also found the sound muffled, with background hiss.
We could not find published HearAdvisor scores for the VOLT 4. BTE aids generally have more room for microphones and amplification than tiny in-canal aids, but that is not a measured result. Assume MDHearing aids are basic amplifiers with presets, not precision devices.
What that means for you: if your main problem is the TV and one-to-one conversation in a quiet room, a basic aid can still help a lot. If your main problem is following conversation in noisy places, look at the higher-graded OTC aids in our best hearing aids for seniors guide.
Price, the “sale”, trial and warranty
MDHearing’s prices per pair currently run from about $297 to $597, compared with several thousand dollars for many clinic-fitted pairs. The catch is presentation: MDHearing shows these as discounts from much higher “regular” prices, which NCOA described as deceptive pricing. Ignore the crossed-out figure and compare the price you actually pay.
- Trial: 45 days. Return the aids within 45 days of delivery for a refund. NCOA notes return shipping is not covered.
- Warranty: 1 year. The optional VIP Care plan (about $200 one-time) extends it and adds video or phone support from a licensed professional.
- Protection plans: MDShield damage cover is sold monthly.
- Paying: OTC hearing aids are usually FSA and HSA eligible; check your plan. Original Medicare does not cover hearing aids, though some Medicare Advantage plans include an allowance.
Getting used to them: the first two weeks
Most returned hearing aids go back because the first week feels strange, not because the aids are faulty. Expect everyday sounds such as running water, rustling paper and your own voice to seem too loud at first. Your brain has stopped noticing them.
- Start with a few hours a day in a quiet room, and increase over one to two weeks.
- Try every dome size. A dome that is too small causes whistling, and one that is too big is uncomfortable.
- Start on the Quiet program at a low volume, and only turn up if speech is still unclear.
- Clean the domes and tubes weekly; wax blockage is the commonest cause of weak sound.
- Use the full 45 days to decide, and keep the box.
See a doctor first if you have sudden hearing loss, loss in one ear only, ear pain, drainage, dizziness or ringing in one ear. These need a medical check, not an OTC aid.
MDHearing vs other OTC hearing aids
MDHearing’s strength is price and simplicity. Its weakness is sound quality and features. Rival OTC aids at similar prices, such as the ELEHEAR range, add Bluetooth streaming, app-based self-fitting and better independent lab grades. Budget brands such as Audien cost less again. All are compared in our best hearing aids for seniors guide.
Hearing loss also raises fall risk. If you are buying for a parent, read our guide on hearing loss and fall risk.
What MDHearing says
The following are MDHearing’s own marketing claims from the product listing, not our independent findings. Details can change over time — check the current Amazon listing for the latest.
- MDHearing describes the VOLT 4 as a rechargeable behind-the-ear OTC hearing aid with about 20 hours per charge, four listening programs, dual microphones, noise reduction and feedback cancellation.
- MDHearing sells its hearing aids as FDA over-the-counter devices for adults with perceived mild-to-moderate hearing loss.
- MDHearing offers a 45-day trial and a 1-year warranty, with paid VIP Care for extended warranty and professional support.
How it compares to other OTC hearing aids
The VOLT 4 earns its place as the simple, no-phone, behind-the-ear option. For better measured sound or Bluetooth streaming, other OTC aids do more for similar money.
- ELEHEAR Beyond Pro (our top OTC pick) — an independent HearAdvisor Grade A, Bluetooth streaming and app self-fitting. Better sound, but you need a smartphone.
- Audien Atom series — cheaper, tiny in-canal aids with no app. The budget option if price matters most.
- MDHearing NEO XS — MDHearing’s near-invisible in-canal model. Smaller, but harder to handle and graded C in independent lab tests.
Frequently asked questions
They are basic but usable for mild-to-moderate hearing loss, especially for TV and quiet conversation. Independent HearAdvisor lab testing graded the NEO XS a C, with little speech benefit in noise. For the best measured sound, higher-graded OTC aids do better. For simple, low-cost, no-phone aids with a 45-day trial, MDHearing is a reasonable start.
For most older adults, the VOLT 4. Behind-the-ear aids are easier to see and handle, it runs about 20 hours per charge, and it uses buttons instead of an app. The tiny NEO XS is harder to handle and tested poorly for speech in noise.
About $297 to $597 per pair direct from MDHearing, according to NCOA in September 2026. The VOLT 4 is about $397 a pair. MDHearing shows these as “sale” prices against much higher regular prices, so compare the price you actually pay. Amazon pricing can differ.
The VOLT MAX 2 adds app control and Bluetooth for about $200 more per pair, but its battery is shorter (about 15 hours against about 20). The VOLT 4 is simpler, with no app and two buttons.
The NEO sits in the ear canal; the NEO XS is about half the size and sits completely in the canal, so it is nearly invisible. The NEO XS PRO adds app control. Smaller aids are harder to handle and their buttons are harder to press.
Yes. MDHearing was founded by Chicago ENT surgeon Dr. Sreekant Cherukuri and sells FDA over-the-counter hearing aids with a 45-day trial. Reviewers have criticized its permanent “sale” pricing, and RetirementLiving reports it is not BBB-accredited, so read the trial and return terms before you buy.
A 45-day trial: return the aids within 45 days of delivery for a refund. NCOA reports return shipping is not covered. Keep the box and accessories.
Original Medicare does not cover hearing aids. Some Medicare Advantage plans include a hearing aid allowance, and OTC hearing aids are usually FSA and HSA eligible. Check your plan.
The VOLT 4, AIR, NEO and NEO XS do not stream calls; you hold the phone to your ear as normal. The VOLT MAX and NEO XS PRO have app control. For streaming calls into the aids, look at Bluetooth OTC models.
