Background

ReSound is pushing custom hearing aids in a new direction with its latest Custom by ReSound lineup—blurring the line between traditional hearing aids and modern wireless headphones.

Custom by ReSound hearing aids are built using the same core technology as ReSound’s top-end hearing aids, with a focus on strong speech clarity and modern Bluetooth connectivity. 

What makes this family stand out is its design: instead of hiding in the ear, Customs by ReSound lean into a headphone-like aesthetic while still being fully custom-molded for comfort and performance.

ReSound offers three in-ear custom styles, giving you flexibility depending on how much visibility, streaming, and convenience you want.

Key Features

Custom Fit with a Modern Look

Each ReSound Custom hearing aid is molded from an impression of your ear, creating a secure, comfortable fit that improves sound quality and retention.

Unlike traditional custom hearing aids, the rechargeable ITE and ITC models feature smooth, rounded outer shells and tactile buttons that look more like premium earbuds.

Built on ReSound Hearing Tech

ReSound Custom hearing aids use the sound processing technology popular in ReSound’s behind the ear models. The sound quality is clear, assertive and snappy, prioritizing speech clarity in noisy environments.

Bluetooth Streaming

Until a few years ago, most in-ear hearing aids didn’t support Bluetooth streaming. That’s changing quickly—especially for larger custom styles. ReSound’s ITE and ITC models now offer Bluetooth streaming from both iPhone and Android devices.

Because these hearing aids more fully seal the ear compared to open-fit designs, music, podcasts, and phone calls sound fuller and richer, with noticeably better bass and clarity. Streaming performance is especially strong compared to open-fit RIC hearing aids.

Easy Handling and Strong Dexterity

ReSound has clearly prioritized ease of use with their flagship in-the-ear product.

Rechargeable models come with a custom-shaped charging case that makes placement intuitive and nearly foolproof. Onboard buttons are smooth, well-positioned, and easy to operate, making this one of the most dexterity-friendly custom products available.

Compare the ReSound Custom Styles

ReSound Custom ITE R / ITC R (Rechargeable)

Best for: Streaming, convenience, and modern design

  • Rechargeable batteries with a custom-molded charging case
  • Bluetooth streaming for music, calls, and media
  • Modern, headphone-like aesthetic
  • Larger footprint than CIC customs, but easiest to handle

These are the “hero” products in the lineup and ideal if you want premium features and strong streaming in a custom form factor.

ReSound Custom CIC (Completely-in-Canal)

Best for: Maximum discretion

  • Sits deep in the ear canal and is nearly invisible
  • Uses disposable batteries
  • No visible exterior design or large controls
  • Limited connectivity compared to larger models

This is the most discreet ReSound Custom option and best if visibility matters more than streaming or ease of handling.

Notes on Sound Quality

ReSound Custom hearing aids deliver clear, crisp speech that we find has a brighter and more assertive tone. Compared to open-fit hearing aids, customs provide stronger low-frequency response, which improves music, media, and phone call quality.

Because these are prescription devices, sound can be professionally fine-tuned over time to match your preferences and listening environments.

Are ReSound Customs Right for You?

If you like the idea of ReSound technology in an in-ear design—or want one of the most dexterity-friendly hearing aids on the market—Customs by ReSound could be a great fit.

  • Choose ITE R or ITC R if you want rechargeable convenience, excellent streaming, and easy handling
  • Choose CIC if invisibility is your top priority

One thing to note: the rechargeable ReSound Custom models are intentionally visible and can resemble wireless earbuds.

Customs By ReSound are a hearing aid product that blurs the line between a pair of modern Bluetooth headphones and a premium, medical-grade hearing aid.

The sleek buttons and black body color look nothing like the hearing aids I remember my grandparents wearing, but I’m pretty sure these are the most dexterity-friendly hearing aids on the market.

As I write this review, I’m listening to a 90s hits Spotify playlist streamed straight into my hearing aids.

In this guide, I’ll talk you through everything I’ve learned about Customs by Resound.

Let’s get into it!

About ReSound

ReSound is the lead hearing aid brand owned by GN Group, the 4th largest maker of hearing aids in the world. GN has headquarters in the outskirts of Copenhagen, but its impact is global, providing products in over 100 countries.  

ReSound hearing aids are available from leading hearing care professionals and are considered one of the most respected brands by audiologists. ReSound was the first brand to feature an iPhone-compatible hearing aid in 2013. They continue to innovate with more intelligent devices, longer battery life, and unique design.

One thing I appreciate about ReSound is their tendency to design products that look just a little bit sleeker than the standard. I'm a big fan of the design in the popular ReSound reciever in canal products, and I think Customs by ReSound are one of the best-looking hearing aids of their kind.

Fun fact. ReSound wasn't always a European company. It was founded by Rodney Perkins, who grew up in Evansville, Indiana, and advanced technology from Bell Labs to create hearing aids.

Fitting Process

Customs by ReSound Custom Earmold Process

Appointment #1 - Hearing Test and Ear Impressions

If you are interested in getting custom hearing aids from ReSound, you’ll want to start by finding a local audiologist. Get started at the top of this page or get in touch with our team to pair you with a local clinic that offers ReSound products.

I worked with my go-to local clinic and set up an initial appointment to test my hearing and gather earmold impressions.

Earmold impressions were taken by filling the canal of my ear with a green paste that was removed a few minutes later. That imprint was then shipped to Resound to create my custom devices.

Appointment #2 - Programming and Adjustments

A few weeks later, I returned to my local clinic to retrieve my custom hearing aids. Each device is slightly different from the other to account for my specific ear shape. One very cool feature of the new Customs by Resound is that the hearing aid recharge case is also custom molded to match the exact shape of each device.

The result is that replacing these devices in the case is almost foolproof.

My audiologist and I sat together as she programmed the new hearing aids and asked me a series of questions. Once they were customized to my hearing loss, we paired the devices to my iPhone (customs also work with Android), and I got back in my car to make my way through afternoon traffic.

Follow Up Appointments - Fine Tuning The Sound

Nearly all hearing professionals offer free follow-up appointments for 1-3 years. Customs by ReSound allow for remote programming adjustments, so when I need to tune-ups I will likely be able to do that from the comfort of home.

Technology

Customs by ReSound Review

Customs by ReSound are packed with the latest hearing technology. Here are some of the highlights.

Customization - For starters, these are full-featured hearing aids with full customization capabilities, impressive sound algorithms, and dual microphones to process background noise.

App controls - The ReSound app gives users control over fine-tuning and preset programs like "restaurant", "outdoor", "music," and more. Users can tweak sound settings and save them as programs in the app.

Bluetooth - Like most Bluetooth hearing aids, Customs by ReSound allow hands-free calling with iPhone (you can leave your phone in your pocket), but you'll need to have your phone close by if you use an Android.

Water Resistant - The components in Customs by ReSound are coated with water-resistant material that makes this product waterproof up in up to 4 feet of water. It’s not recommended that you swim in the product, but an accidental shower shouldn’t affect performance.

Rechargeable - Each product comes with a custom molded hearing aid charge case. Three hours of charging gives a full day of use.

Final Thoughts

If you want an in-ear hearing aid that delivers music and podcasts with near-AirPods-level quality—or a design that looks more like modern headphones than a traditional hearing aid—Custom by ReSound is a strong choice.

If you’re looking for an in-ear option sold over the counter, consider Eargo 8, or compare ReSound customs with other custom-molded options from Starkey and Oticon.

Need help deciding? Call or text our team at 1 (833) SOUNDLY.

A great option for anyone looking for a full-featured hearing aid that is easy to handle.
