Phonak
Audéo Sphere Infinio
$3,598 – $4,898 / pair
Per pair; two tech levels (I70/I90). Battery up to 56h in standard mode, ~10–11h with the AI Sphere mode engaged. Clinic pricing varies.
Phonak's flagship rechargeable RIC carries a dedicated DEEPSONIC AI chip that separates speech from noise in real time — and it earned the top speech-in-noise score of any prescription hearing aid in HearAdvisor's independent lab testing. At $3,598–$4,898 per pair, it sits at the premium end of the market. In exchange, you accept a larger body, roughly 10–11 hours of battery in AI mode, and no telecoil or CROS support.

Our Take
Noisy rooms are where most hearing aids fall apart, and that's exactly the problem Phonak built this one to solve. The Audéo Sphere Infinio carries a second processor — the DEEPSONIC AI chip, with roughly 53 times the processing power — dedicated entirely to pulling speech out of noise in real time. The results aren't just marketing: HearAdvisor's independent lab ranked it #1 for speech-in-noise among prescription hearing aids, with a SoundScore of 4.58 after the free Infinio Ultra firmware update. Phonak claims up to 10.2 dB of SNR improvement and up to 35% less listening effort.
Running Sphere mode continuously drains the battery in roughly 10–11 hours — a steep drop from the 56 hours you get in quiet settings. The second chip also makes the body noticeably larger than a typical RIC. There's no telecoil for looped venues and no CROS option on the Sphere model. And while the hardware is Auracast-ready, Bluetooth LE Audio still isn't enabled as of mid-2026, so you're waiting on firmware Phonak hasn't shipped.
Whether it's worth it comes down to how much of your life happens in noise. This is a premium buy at $3,598–$4,898 per pair, and if your days are mostly quiet conversation, the Oticon Intent ($2,898–$4,598) or ReSound Vivia ($2,598–$4,098) cost less in smaller packages. But if restaurants and group dinners are where you lose words, nothing independently tested does better — your hearing care professional can help you choose between the I70 and I90 tech levels.

Phonak Audéo Sphere Infinio Questions
If speech in noise is your biggest problem, there's a real case for it. HearAdvisor's independent lab ranked it #1 for speech-in-noise among prescription hearing aids, and the free Infinio Ultra update improved battery efficiency by roughly 30%. That said, $3,598–$4,898 per pair is premium pricing — peers like the ReSound Vivia start around $2,598 — so if quiet listening is your norm, you may not need what you're paying for.
It comes down to priorities. In HearAdvisor's independent testing, the Sphere Infinio earned the top speech-in-noise score of any prescription hearing aid, so it has the measurable edge in loud places. The Oticon Intent starts lower, at $2,898 per pair versus $3,598. Keep in mind the Sphere's second chip makes it noticeably larger than typical RICs, and its AI mode cuts battery life to about 10–11 hours of continuous use.
Up to 56 hours in quiet settings after the October 2025 Ultra firmware update. The catch is Sphere mode: running the AI speech-in-noise processing continuously drops battery life to roughly 10–11 hours, up from about 7 before the update. These aids are rechargeable only — there's no disposable-battery version — so a mixed day of quiet and noise will land you somewhere between those two numbers.
Not yet. The hardware is Auracast-ready, but Bluetooth LE Audio and Auracast still weren't enabled as of mid-2026 — that's waiting on a firmware update. Standard Bluetooth works well in the meantime, with true hands-free calling and streaming on both iPhone and Android, plus 8 paired devices and 2 active at once. There's no telecoil, so hearing loops aren't an option either.
