ReSound makes small hearing aids that sit behind the ear, custom models that fit inside it, and more powerful aids for severe hearing loss. Sensia is its newest premium family. Enzo IA and Savi cover different parts of the range, while Vivia remains listed as the previous premium generation.
We fit ReSound regularly at Alto. We choose the hearing aid alongside the dome or custom earmould, any accessories and the support needed afterwards. Someone struggling to follow a meeting across a table may need a different combination from someone whose main difficulty is conversation at home.

Who are ReSound?
ReSound is a Danish hearing aid manufacturer within GN Hearing. Its range includes rechargeable and battery-powered aids, phone connectivity and remote microphones. The functions available vary by model and style.
Current ReSound hearing aids
The model family tells you which generation of technology you are looking at. The style tells you where the aid sits and how it is powered. A custom in-ear aid can belong to Sensia or Savi, so “Custom” is not a separate equivalent to those families.
| Range | Models and styles | Main distinction |
|---|---|---|
| Sensia | Receiver-in-ear and custom in-ear models | ReSound’s newest premium family; the full Intelligent All-Around feature is specific to microRIE 9 |
| Enzo IA | Rechargeable super-power behind-the-ear aids | Higher output for severe to profound hearing loss |
| Savi | Receiver-in-ear and custom styles | The more affordable family, with connectivity depending on the style |
| Vivia | Rechargeable and battery receiver-in-ear models | The previous premium generation, still listed by ReSound |

ReSound Sensia
Sensia is ReSound’s latest premium family. It includes rechargeable microRIE hearing aids, which sit behind the ear with a fine wire to the receiver in the ear canal, as well as battery-powered and custom in-ear options.
ReSound calls its new sound-processing system Intelligent All-Around. It combines automatic recognition of the listening environment, directional microphones and AI-based noise reduction. The full system is available only on the rechargeable microRIE at technology level 9.
This processing is designed to help speech stand out in competing noise. How clearly you can distinguish words, and how the aid is fitted, also affect the result.
Sensia also has CROS options for single-sided deafness and bimodal options for use alongside a compatible cochlear implant. These need a separate assessment of the hearing in each ear.
Our ReSound Sensia guide explains how the processing favours speech from the person you face and which models include Intelligent All-Around.
ReSound Enzo IA
ReSound Enzo IA is built for people with severe to profound hearing loss who need a super-power hearing aid. It is a rechargeable behind-the-ear model, usually fitted with a custom earmould.
For this level of hearing loss, the hearing aid needs to provide enough usable amplification without becoming uncomfortable, distorted or prone to feedback. The earmould, its seal and venting, and the feedback settings all need attention. Enzo IA is relevant when the fitting needs more output than a smaller receiver-in-ear aid can provide.
Enzo IA supports Bluetooth LE Audio and Auracast. ReSound quotes 28 hours of use from a full charge, or 20 hours with audio streaming for 50% of the time. These are manufacturer figures; use and settings affect battery life.
Our Enzo IA guide explains the power range in more detail.
ReSound Savi
Savi is the more affordable family in ReSound’s range. It includes rechargeable and battery receiver-in-ear aids, plus custom in-the-canal (ITC) and completely-in-canal (CIC) styles.
Some Savi models support Bluetooth LE Audio and Auracast. The smallest CIC is non-wireless, and ReSound excludes hands-free calling on its ITC and CIC styles. Choosing a custom style can therefore change the phone functions available.
ReSound Vivia and earlier models
Vivia was ReSound’s premium range before Sensia. ReSound still lists it, with rechargeable and battery receiver-in-ear models. It has speech-in-noise and connected features, although the processing available depends on the model and technology level.
ReSound also continues to list Nexia, Omnia and older Enzo products. An older generation can still meet someone’s needs. A quotation should identify the family, style and technology level so you can compare it with another offer accurately.
Our video below was recorded when Vivia launched. It covers that generation, rather than Sensia.
Custom ReSound hearing aids
Custom hearing aids are made to fit the shape of your ear. Everything sits in the ear, with no hearing aid body behind it. For some people, inserting one piece is easier than placing an aid behind the ear and then positioning the earpiece.
The current Sensia custom range includes rechargeable in-the-ear (ITE) and ITC models, a battery-powered wireless ITC and a non-wireless CIC. The CIC cannot stream phone audio. ReSound also excludes hands-free calling on the battery-powered ITC. Savi has its own custom options, with different features.
Ear canal shape, wax, ventilation and the amplification needed can limit which style will work. A small aid may also be harder to handle. Our custom in-the-ear guide explains the fitting considerations, while the invisible hearing aids guide covers the smallest styles.
ReSound Smart 3D app and phone compatibility
The Smart 3D app lets you change volume and programmes without reaching for the hearing-aid buttons. With compatible models, you can save preferred settings and check the battery level of rechargeable aids.
Sound controls depend on the hearing aid and the programme. They can include adjustments for background noise and speech focus. The app also has an Auracast Assistant for compatible aids, used to find and select available broadcasts.
ReSound Assist can support remote fine-tuning where the clinic has set it up. Your audiologist can send revised settings to the app for you to install. An appointment may still be needed to check the physical fit or investigate discomfort, feedback or a change in hearing.
App control, streamed audio and hands-free calls have separate compatibility requirements. Our guide to hearing aids and phone compatibility explains what to check for your exact phone and hearing-aid model.
ReSound accessories and Auracast
A remote microphone can help when the person speaking is too far away for the hearing-aid microphones to pick up speech clearly. ReSound’s Multi-Mic+ can sit on a table or be clipped to a speaker’s clothing. It sends the microphone signal to compatible hearing aids, which can be useful in meetings, lectures or conversation across a noisy table.
The TV-Streamer+ sends television audio directly to compatible hearing aids at a volume set for the wearer. Someone else in the room can keep the television at their preferred level. Accessory compatibility needs checking against the exact hearing-aid generation. Our hearing aid accessories guide explains the different uses.
Auracast allows suitable hearing aids to receive a shared audio broadcast from a compatible transmitter. That could be television audio at home or a broadcast in a venue. The transmitter or venue must provide a supported broadcast; the feature does not make every television or public sound system connect automatically.
Which ReSound hearing aid is best for you?
We look at hearing levels and speech-in-noise results alongside the conversations you are missing. The amount of amplification needed is part of the decision. Speech-in-noise results help us judge whether microphone processing or an accessory could help you follow conversation in a busy room.
The fitting includes the receiver and dome or earmould, as well as the aid. We check the amplification in the ear and adjust it for the hearing loss. Our guide to hearing aid fitting explains that process.
Handling and daily use also affect the choice. We check whether you can insert and remove the aids, use the charger or change batteries, and manage any accessories. We then plan follow-up around how you hear with them. Our hearing aid treatment plans explain the care included.
How does ReSound compare with other brands?
We fit several manufacturers at Alto and regularly use ReSound. A difference in sound, physical fit, phone functions or accessories can matter more to an individual than a manufacturer’s position in a feature table.
Our hearing aid brands comparison covers those differences across the main manufacturers. Our best hearing aids guide compares current models.
How much do ReSound hearing aids cost?
ReSound prices depend on the family, technology level, style and care included. Two quotes with the same brand name may cover different devices or different amounts of support.
Compare the exact model and whether the price covers one aid or a pair. The quotation should also identify the fitting and verification, follow-up appointments, warranty, repairs and any earmoulds or accessories included. A super-power Enzo IA fitting may involve different clinical work and coupling from an open receiver-in-ear fitting.
At Alto, hearing aids are supplied as part of a treatment plan that includes fitting and ongoing care. Our UK hearing aid prices guide explains the costs and what to compare.
The video below explains why the care included affects the price.
