If you are comparing the Signia Pure Charge&Go IX vs Phonak Audéo Sphere Infinio, you are already looking at two of the strongest rechargeable RIC hearing aids available in India today. Both sit at the premium end. Both are Bluetooth-enabled, rechargeable and IP68 rated. And both cost a significant amount of money.
So the honest question is not “which is the best hearing aid.” It is “which one is better for your ears, your daily life and your budget.”
Our audiologists fit both devices regularly across our 75+ hearing clinics in major cities across India. This guide explains how they actually differ, what each one costs, and who each one genuinely suits including the situations where a different device altogether may serve you better.
Summary
Both are premium rechargeable RIC hearing aids, but they have different strengths. Phonak Audéo Sphere Infinio uses the dedicated DEEPSONIC AI chip for speech in heavy background noise, while Signia Pure Charge&Go IX focuses on natural conversation, longer battery life, own-voice comfort, and tinnitus support.
At Ear Solutions, kit MRPs range from ₹3,46,990 (Signia 3IX) to ₹8,75,000 (Phonak Sphere i90). Features like EMI and offers may vary.
Neither is best for everyone. Your hearing loss, lifestyle, comfort, listening environments, and budget should guide the choice. A professional hearing test and real-world trial are recommended before buying.
Key Takeaways
- Phonak Audéo Sphere Infinio is a strong choice for people who frequently struggle to hear speech in noisy environments, thanks to its dedicated DEEPSONIC AI processing.
- Signia Pure Charge&Go IX stands out for longer battery life, natural own-voice sound, tinnitus support, and a lower starting price.

- Best way to decide: Get a professional hearing test and, where available, a real-world trial before making your final choice.

How the Two Devices Actually Differ
Phonak Audéo Sphere Infinio: Better for Noisy Places
The Phonak Audéo Sphere Infinio is designed with a dedicated DEEPSONIC AI chip that focuses on separating speech from background noise. This can be especially useful at weddings, busy restaurants, family functions, and open offices.
It has shown strong speech-in-noise performance in independent testing, but there are a few trade-offs: AI noise processing can reduce battery life, and the Sphere does not support telecoil or CROS/BiCROS.
Note: After a 2026 firmware update, the model is also referred to as the Audéo Infinio Ultra Sphere. The hardware remains the same.
Signia Pure Charge&Go IX: Better for Conversation & Comfort
The Signia Pure Charge&Go IX takes a more conversation-focused approach. Its RealTime Conversation Enhancement helps keep speech clear as conversations change around you.
It also offers Own Voice Processing 2.0, which can make your own voice sound more natural, along with built-in tinnitus support.
Battery life is another advantage, with up to 39 hours for the 3IX and around 31 hours for the 7IX, including streaming. Both are IP68-rated, making them suitable for everyday use and humid conditions.
Signia Pure Charge&Go IX vs Phonak Audéo Sphere Infinio Prices in India
Before comparing prices, note that the figures below are for a complete kit two hearing aids plus a charger, not a single device.
| Model | What's Included | MRP (Kit) |
|---|---|---|
|
Signia Pure Charge&Go 3IX |
2 hearing aids + charger |
₹3,46,990 |
|
Signia Pure Charge&Go 7IX |
2 hearing aids + charger |
₹7,69,990 |
|
Phonak Audéo Infinio Sphere i70 |
2 hearing aids + charger |
₹5,90,000 |
|
Phonak Audéo Infinio Sphere i90 |
2 hearing aids + charger |
₹8,75,000 |
Prices and available offers can change, so confirm the latest price with Ear Solutions before buying.
At the premium end, the Phonak i90 costs about ₹1.05 lakh more than the Signia 7IX. Whether that extra cost is worthwhile really depends on your lifestyle. If you’re mostly at home or in quieter places, a lower technology level may be enough. If you’re regularly dealing with busy offices, functions, travel, or noisy environments, the higher-end options may be worth considering.
For many buyers, the Signia 3IX can be a practical middle-ground, offering a lower price while remaining part of the Pure Charge&Go IX range.
Ultimately, don’t choose based on price alone. Your hearing test, lifestyle, and listening needs should guide the final decision.
Best For: Honest Recommendations
Choose the Phonak Audéo Sphere Infinio if:
- Noisy environments are your single biggest frustration
- You attend large functions, weddings or crowded restaurants frequently
- You work in meetings, open offices or client-facing roles
- You want maximum multi-device Bluetooth connectivity
- Budget is not the deciding constraint

- Your own voice sounding unnatural has bothered you before
- You experience tinnitus alongside hearing loss
- You want premium performance at a more accessible price point
- Most of your listening happens at home, in small groups and on calls
Consider a different device altogether if:

- You need telecoil or CROS/BiCROS the Sphere model supports neither
- You want maximum discretion an invisible CIC or IIC style may fit better
- Your budget is tighter well-fitted mid-range options from Oticon, Widex, ReSound or Starkey deliver excellent everyday results, and our audiologists will say so honestly
Why Professional Fitting Decides the Outcome
The right hearing aid is not just about the brand or price. Proper programming and fitting can make a major difference in how comfortably and effectively you hear.
A professional assessment is especially important if you have sudden hearing loss, hearing loss in one ear, ear pain, discharge, dizziness, or persistent tinnitus. These symptoms may need medical evaluation before using a hearing aid.
At Ear Solutions, the process typically includes:
- Free PTA hearing test with a qualified audiologist
- Lifestyle discussion to understand where you struggle to hear
- Real-world trial of suitable hearing aids
- Fine-tuning based on your experience
- Ongoing aftercare, including cleaning, servicing, and adjustments
Ear Solutions has clinics across Delhi NCR, Mumbai, Bengaluru, Hyderabad, Chennai, Kolkata, Pune, and other cities, with home visits available in select locations.
Hearing aids don’t restore normal hearing, but when properly matched and fitted, they can make conversations easier and reduce listening effort in everyday situations.
Conclusion
Between the Signia Pure Charge&Go IX and Phonak Audéo Sphere Infinio, there is no single winner. If you regularly struggle in busy restaurants, weddings, or noisy offices, the Phonak Sphere’s dedicated AI processing may be worth the higher price. If you value longer battery life, natural own-voice sound, tinnitus support, and better value, Signia Pure Charge&Go IX may be the better fit.
At Ear Solutions, we see many users do very well with mid-range options, depending on their hearing needs and lifestyle. The most expensive device isn’t always the best choice.
What matters most is proper hearing assessment, fitting, and fine-tuning. Get your hearing tested, discuss your daily listening challenges with an audiologist, and try your shortlisted device in real-world situations before making your final decision.
