Phonak Infinio Ultra is the newer, standard-sized rechargeable update with smarter scene detection, easier pairing and a wax-protection system. Infinio Sphere adds a separate DEEPSONIC AI chip aimed at speech in very noisy places, at a higher price and slightly larger size. Phonak prices in India start around ₹24,999, and Sphere sits at the top end.
You sit in a meeting, then a noisy canteen, then a call on the way home. If you are choosing between these two Phonak families, you are really asking one thing: do I need the extra noise chip, or is the Ultra enough? This guide from Sound Comforts breaks down the differences in plain language, along with what we could verify about the Phonak hearing aid price in India.
Summary
- Infinio Ultra is Phonak’s updated Infinio platform; Sphere adds a dedicated DEEPSONIC chip for speech in noise.
- There is also an Ultra Sphere, which combines both.
- Sphere Mode uses more battery; Phonak and review sources list a minimum of 16 hours with heavy use.
- India prices for each version are shared on request; Sphere listings run into lakhs.
What is the difference between Phonak Infinio Ultra and Infinio Sphere?
The Infinio Ultra improves how the hearing aid detects your surroundings, pairs with phones and protects against wax. The Infinio Sphere adds a second, dedicated AI chip that runs a speech-in-noise program, which the Ultra does not have in its standard version.
Phonak launched the Infinio Ultra range for order through hearing care professionals on 22 October 2025. It includes both a standard Audéo Infinio Ultra and an Audéo Sphere Infinio Ultra, so the name “Ultra” is not only one product.
What is new in Phonak Infinio Ultra?
The main updates are upgraded AutoSense 7.0 scene detection, one-step pairing with phones and EasyGuard wax protection. Phonak says its AI now recognises many more real-world sound situations, with greater accuracy than the earlier Infinio.
- Easier pairing: pair from your phone’s Bluetooth menu, with up to two simultaneous connections.
- EasyGuard: you wipe the surface instead of changing wax filters; Phonak claims up to 38% fewer service visits.
- Auracast-ready: it needs a later firmware update to switch on.
- IP68: listed for the Audéo Infinio Ultra on a review page.
What does the Sphere add with its DEEPSONIC chip?
The Sphere adds a separate processor running Spheric Speech Clarity, which uses deep neural networks to pull speech out of noise. Reviewers describe its speech clarity in loud places as outstanding, though it can mean trade-offs in size and discretion.
The Ultra Sphere carries a newer version of this feature, which Phonak says is more efficient. If you often struggle in restaurants or group conversations, this is the part that matters.
How do the two compare on battery life?
The Ultra is reported at about 31 hours per charge under normal use and streaming, while Sphere Mode drains faster. For the Ultra Sphere, sources list a minimum of 16 hours with 3 hours of Sphere Mode and 5 hours of streaming, and up to 56 hours without them.
A 30-minute quick charge can add around 6 hours, and a full charge takes about 3 to 4 hours. Real use varies, so check a full day during your trial.

How much do Phonak Infinio Ultra and Sphere cost in India?
Sound Comforts lists Phonak hearing aids in India from about ₹24,999 up to ₹7,99,999, and the Infinio Ultra and Sphere models are marked “contact for price” with the exact figure shared on request. Sphere listings elsewhere in India run roughly from ₹5,90,000 to ₹8,75,000, depending on level and version.
Treat these as listed figures, not final quotes. You can ask for the latest Phonak price list from Sound Comforts and get the price for your level in writing, stating whether it covers one ear or both.
Which one is better for people aged 35 to 55?
If your days include open offices, conferences, restaurants and family gatherings, the Sphere is built for that and may be worth the premium. If most of your day is quieter and you value a discreet look and a lower price, the Ultra is usually enough.
Your hearing test and daily routine should decide, not the model name. Start with one realistic scenario, such as your noisiest weekly meeting, and test both in it.
Can existing Infinio owners upgrade?
Phonak has said former Infinio owners can get the same Ultra benefits through a firmware update from their provider, possibly for a fee. Whether this applies to your exact device is something your audiologist should check.
The extra Sphere chip is hardware, so a firmware update does not turn a standard Infinio into a Sphere.
What about EMI, trial and warranty?
Sound Comforts mentions 0% EMI options, a free hearing aid trial and extended warranty on its Phonak page. The same page says trial length, EMI conditions and warranty details depend on the model and purchase, so ask for them in writing.
Also ask whether the quote includes the charger, accessories and follow-up fine-tuning.
What should you ask before buying?
Ask for a hearing test result, why a particular level suits you, and the total ₹ price for one and both ears. Ask for a trial in the places where you struggle most and the terms for returning it.
Visit one of the Sound Comforts clinics to compare the Ultra and Sphere side by side.
Should you see an ENT doctor first?
Yes, in some cases. Sudden hearing loss, ear pain, discharge, dizziness or loss in only one ear should be checked by an ENT doctor before you buy a hearing aid.
Audiologists test hearing and fit devices; they do not diagnose or treat ear disease. Hearing aids improve hearing and quality of life, but they do not restore normal hearing.
Conclusion
The Phonak Infinio Ultra and Infinio Sphere share the same smart platform, so the real choice is whether you need the extra DEEPSONIC chip for loud, crowded places. For busy people aged 35 to 55 who live in noisy rooms, the Sphere can justify its higher price, while the Ultra offers a smaller, lighter-on-the-wallet way to get modern Phonak technology. Take a hearing test, try both in your own noisy situations, and get the ₹ price, warranty and trial terms in writing before you decide.
