Quick Answer: For most buyers cross-shopping premium prescription hearing aids, ReSound wins on natural sound and future-proof connectivity — its 2026 flagship, the Nexia, was among the first hearing aids built on Bluetooth LE Audio with Auracast broadcast support, and the ReSound ONE’s M&RIE microphone placement delivers unusually natural sound localization. Phonak’s Audeo Sphere Infinio counters with a dedicated AI chip (DEEPSONIC) that isolates a single talker in noise, plus a power platform (Naida) built for severe-to-profound loss. Both are prescription-only, fitted by an audiologist, and typically run $2,500-$7,000 per pair — in line with the ~$3,000 average reported by the President’s Council of Advisors on Science and Technology (PCAST).
ReSound and Phonak are two of the “big five” global hearing-aid makers, and both are engineered by parent companies that also sell a cheaper OTC line — ReSound’s parent GN also makes the OTC Jabra Enhance Select, while Phonak’s parent Sonova also makes the OTC Sennheiser All-Day Clear. That shared-technology angle makes this comparison useful even if you end up skipping the clinic entirely. Here’s how the two prescription flagships and their supporting lineups actually compare.
ReSound vs Phonak at a glance, by the numbers
- Bluetooth LE Audio with Auracast is a ReSound-first — the ReSound Nexia was promoted as one of the first hearing aids in the world built on the new low-energy audio standard, per GN Hearing, ahead of most rivals including Phonak.
- A dedicated AI chip is a Phonak signature — the Phonak Audeo Sphere Infinio adds a second processor (DEEPSONIC) running Spheric Speech Clarity, purpose-built to separate one talker from background noise.
- 30 hours vs universal streaming — ReSound cites up to 30 hours of use per charge on the Nexia; Phonak’s Audeo line has long offered direct Bluetooth streaming to both iPhone and most Android phones without an intermediary device.
- $4,000-$6,000 vs $4,500-$7,000 — ReSound’s flagship Nexia typically runs $4,000-$6,000 a pair, while Phonak’s flagship Sphere Infinio typically runs $4,500-$7,000 a pair, both above the roughly $3,000 PCAST average for a prescription pair.
- 28.8 million U.S. adults could benefit from a hearing aid per the NIDCD (National Institute on Deafness and Other Communication Disorders), yet fewer than one in three adults over 70 who could benefit has ever used one — the underserved market both premium brands compete for.

The case for ReSound
ReSound Nexia
- One of the first hearing aids built on Bluetooth LE Audio with Auracast-ready broadcast streaming, per GN Hearing.
- Sister model ReSound ONE pioneered M&RIE — a third microphone in the ear canal for more natural sound localization.
- Very small Micro RIE form factor that sits discreetly behind the ear.
- Same GN engineering powers the OTC Jabra Enhance Select at a fraction of the price.
Once you’re fitted with a prescription pair, domes and wax guards become a recurring purchase, not a one-time one — try Amazon Prime free for 30 days so reorders land in two days instead of a week. ReSound’s biggest practical edge over Phonak is sound quality and connectivity that’s ahead of the standard curve: if natural sound localization and being first to public Auracast broadcast audio matter more to you than raw noise-isolation horsepower, no rival brand currently beats it on those two fronts together.

The case for Phonak
Phonak Audeo Sphere Infinio
- Dedicated AI chip (DEEPSONIC) runs Spheric Speech Clarity to pull one voice out of a noisy room in real time.
- Universal Bluetooth streams calls and media directly to both iPhone and most Android phones.
- Works with Phonak's Roger remote-microphone system for classrooms, meetings, and restaurants.
- The Naida power platform extends the same tech to severe-to-profound loss, which ReSound's lineup doesn't have a direct equivalent for.
Phonak’s biggest practical edge over ReSound is capability at the harder end of the spectrum: a dedicated AI chip purpose-built for noise isolation, genuinely universal streaming that predates ReSound’s LE Audio push, and a power BTE (Naida) built for severe-to-profound loss — a slot ReSound’s lineup doesn’t fill the same way. Read our full Phonak hearing aids review for the complete lineup.
Which should you buy?
- Choose ReSound if natural sound localization matters most to you, you want to be an early adopter of Bluetooth LE Audio and Auracast public broadcast audio, or you’d rather skip the clinic later and switch to the same-parent OTC Jabra Enhance Select.
- Choose Phonak if you struggle most in noisy rooms and want dedicated AI processing for it, you switch between iPhone and Android, your hearing loss is closer to severe-to-profound, or you’d rather skip the clinic later with the same-parent OTC Sennheiser All-Day Clear.
- Choose neither, for now, if your hearing loss is perceived mild-to-moderate and budget matters more than premium AI or connectivity features — a self-fitting OTC pair like the Jabra Enhance Select covers most everyday needs for a fraction of the price, and our best OTC hearing aids ranking covers the rest of that market.
Both brands appear alongside the rest of the field in our best hearing aid brands roundup and our overall best hearing aids ranking.

When to see a professional instead of comparison-shopping
ReSound and Phonak are both prescription devices, so a licensed audiologist is already part of the process — but get evaluated promptly, rather than shopping by spec sheet, if any of these apply:
- Your hearing loss is severe, came on suddenly, or affects one ear only — see our severe hearing loss guide as background, then book a medical evaluation.
- You have ear pain, drainage, or a history of ear infections.
- Your tinnitus is pulsing or one-sided — read our tinnitus guide and see a doctor first.
- You’re fitting a child — both ReSound and Phonak make devices that can suit pediatric loss, which needs a pediatric audiologist, not a general comparison article.
The bottom line
There’s no wrong choice between ReSound and Phonak — both are top-five global brands with genuinely different strengths. ReSound’s Nexia wins on natural sound (M&RIE) and future-proof Bluetooth LE Audio with Auracast; Phonak’s Audeo Sphere Infinio wins on AI-driven noise isolation and severe-loss capability via Naida. Expect $2,500-$7,000 per pair from either, fitted by an audiologist, with value-tier options (OMNIA, Lumity) landing closer to the $3,000 PCAST average. If your loss is mild-to-moderate and that price is the sticking point, each brand’s own parent company sells a cheaper OTC sibling — Jabra Enhance Select for ReSound, Sennheiser All-Day Clear for Phonak. Otherwise, ask your audiologist to demo both — or browse ReSound and Phonak accessories on Amazon while you decide.
