The MDHearingAid Volt+ is one of three core models in the MDHearingAid lineup, and the most promising one at first sight. It combines many of my favorite features, comes from an established family, and looks a significant improvement after my MDHearingAid AIR review.

To really know what we’re in for, this MDHearingAid Volt+ review will dive into the specifics for this hearing aid. We’ll find out the pros, cons, and alternatives for this model. Before giving you a final buying advice, you’ll know exactly how I got to my conclusion.
As always, I’ve included a 30-second review for the MDHearingAid Volt+ in this article for visual learners. You can find it at the bottom of this post and see all of 30-second reviews in order of preference on this page.

Key features of the MD HearingAid Volt+
The Volt+ has some noteworthy key features: it’s rechargeable, water-resistant, and has dual microphones. Let’s look at these in order.
First, the rechargeable batteries use the charging case that has recently become popular: you charge the case, then pop the hearing aids into the case, which charges the devices in turn. A fully-charged case will provide your hearing aids with three battery cycles (at 24 hours each).
Next, the Volt is water-resistant. This is good news for anyone who’s ever lost a pair of hearing aids after being surprised by rain. The IP57 rating isn’t the highest around, but it’s good to see your hearing aids are protected against light rain and sweat.
Then there are the dual microphones. I keep contemplating whether dual microphones are a key feature or have become a new standard feature, but for now I’ll include it. These dual microphones help you locate the direction of sound and filter out unwanted background noise.
The MDHearing Volt+ is featured as:
* One of the best hearing aids under $400
Who is this hearing aid for?
With a maximum peak gain of 40dB, the MDHearingAid Volt is suitable for mild to moderate hearing loss. The rechargeable case makes the Volt attractive for travelers, as the charging case makes you less reliable on finding an outlet or remembering your batteries when you leave the house.
How well does the MD HearingAid Volt+ work?
Aside from the key features, the Volt works well, too. The volume wheel helps you select a precise volume, and the four different sound programs ensure the best program in certain settings. Battery life is up to par, and the dual microphones add another layer of defense in battling background noise. Compared to the AIR, the base model, the Volt+ has better feedback cancellation technology.
When you order the Volt+, you get a cleaning tool, a charging case, and one pair of domes. To get different dome sizes, you need to add those to your order.
What’s not to like about the MDHearingAid Volt+?
Although the Volt+ fits a lot better with its direct competition than the previously reviewed AIR, it still doesn’t outperform its competitors. The best example is the water-resistant rating of IP57 – Neosonic’s waterproof model, the Neosonic MX-RIC has an IP65 rating. For every good feature this model offers, there’s a competitor that offers a better deal.
Then there is also the occasional complaint that taking off your glasses accidentally turns the volume wheel.
Hearing aids that are good alternatives
Since writing this review, the Volt+ has a successor: the MDHearingAid Volt MAX. This newer model is a major improvement. Aside from that one, there are a few other popular models: the Neosonic MX-RIC and the Otofonix Helix. Of those two (and all three), the VOLT MAX is the best option.
If you’re looking for a better option and have the budget, you should consider the Neosonic MX Smart or the Otofonix Sona.
For alternatives that are lighter on your budget, consider the basic Neosonic MX.
Should you buy the MD HearingAid Volt+?
I hate to say it, but no. Not that the MDHA Volt is a bad hearing amplifier, it most definitely isn’t. It’s just that the Neosonic MX-RIC offers everything the Volt+ has, but a little better. Better protection against water damage, different dome sizes, a one-year warranty, and a battery that charges in half the time. Without that competition, you definitely should have bought the Volt+.
