ReSound's Enzo IA is a super-power BTE hearing aid for severe to profound hearing loss, launched in August 2025 as the successor to the Enzo Q. It runs $3,198 to $4,598 per pair depending on tech tier, and pairs high-gain power with Bluetooth LE Audio, Auracast, and up to 28 hours of rechargeable battery life.

need a disposable-battery option or prefer a smaller receiver-in-canal style over a BTE.

Our Take
Power aids have long been the last to get modern connectivity, and the Enzo IA finally closes that gap. Built for severe to profound hearing loss, it brings Bluetooth LE Audio, Auracast, and hands-free calling to a category where those features have been rare. It runs on GN's 360 chip with real-time environment classification, and the Clear Focus beamformer delivers a 2.7 dB signal-to-noise improvement — 93% of users preferred it in noise. DFS Ultra III feedback management matters too, because whistling is a constant battle at high gain levels.
Compared with the older Enzo Q, the loss is the disposable-battery option — the Enzo IA is rechargeable only, so if you rely on swapping in fresh batteries mid-day, that safety net is gone here. The battery is rated up to 28 hours, but heavy streaming pulls that down to about 20. It also skips the dedicated DNN chip found in ReSound's Vivia flagship, and as a BTE it's bulkier than receiver-in-canal aids — though that's the trade for this much power.
Against the Phonak Naída Lumity, which starts lower at $2,798, the Enzo IA's edge is its newer LE Audio and Auracast streaming. Its own range of $3,198 to $4,598 per pair sits at typical prescription power-aid pricing, and the Oticon Xceed matches that range but is an older platform. If your loss sits in the severe-to-profound range and streaming matters to you, this is one of the strongest cases going — your hearing care professional can confirm the fit.

ReSound Enzo IA Questions
The Enzo IA costs $3,198 to $4,598 per pair, with $4,598 buying the premium tier 9 technology — tiers 7 and 5 cost less. For that you get a super-power aid with Bluetooth LE Audio, Auracast, hands-free calling, and up to 28 hours of rechargeable battery. If you have severe to profound loss and want current streaming tech, the price is in line with peers like the Oticon Xceed, which spans the same $3,198 to $4,598 range.
Both are prescription power aids for severe to profound hearing loss. The Naída Lumity starts lower, at $2,798 versus the Enzo IA's $3,198, with both topping out at $4,598 per pair. The Enzo IA, launched in August 2025, counters with newer connectivity: Bluetooth LE Audio with Auracast, MultiConnect dual-device pairing, and hands-free calling on iPhone 11+ and Android 13+. Which suits you better depends on your fitting needs and how much streaming matters.
The Enzo IA is rated for up to 28 hours on a full charge. If you stream audio about half the day, expect closer to 20 hours — still enough to get through a long day without a top-up. One thing to know: it's rechargeable only. Unlike the older Enzo Q, there's no version that takes disposable batteries, so you can't swap in a fresh cell if you're caught away from the charger.
Yes. The Enzo IA includes Bluetooth LE Audio with Auracast, the newer broadcast standard that lets hearing aids tune into shared audio streams in public places as venues adopt it. It also keeps a telecoil, so you can still use existing hearing loop systems in theaters, churches, and airports. Having both in one super-power BTE means you're covered for today's loop installations and tomorrow's Auracast rollouts.
