Written by USA Hearing Experts  »  Updated on: June 04th, 2025

Choosing the right hearing aid is essential for achieving optimal hearing and comfort in daily life. Two of the most advanced options in the Phonak lineup are the Phonak Audeo Infinio Sphere i90 and the Phonak Audeo Lumity L90 R. While both belong to the premium segment, they offer distinct technologies and benefits. Here's a detailed comparison to help you understand which one might be the better fit for your needs.

Technology and Sound Processing

Phonak Infinio Sphere i90 is powered by Sphere Sound, an innovative platform that prioritises natural, immersive hearing. It focuses on balancing ambient sounds, ensuring that wearers can stay connected to their surroundings without feeling overwhelmed. The i90 model, being one of the top-tier offerings, is designed to deliver seamless transitions between quiet and noisy environments with ease.

Phonak Audeo Lumity L90 R, on the other hand, utilises SmartSpeech Technology, which is optimised for speech understanding, particularly in challenging listening situations. This technology prioritises speech clarity, enabling wearers to focus more effortlessly on conversations, even in noisy environments like restaurants or public gatherings.

If your primary concern is natural and balanced hearing, Infinio Sphere i90 is ideal. But if your focus is sharp speech understanding, Lumity L90 R leads.

Design and Wearability

Both devices feature a Receiver-in-Canal (RIC) design, known for being discreet and comfortable. However, the Lumity L90 R is part of Phonak’s latest design evolution with an ergonomic shape and modern finish. It is slightly slimmer and may appeal more to those looking for a stylish hearing aid.

The Infinio Sphere i90 also maintains a compact and sleek appearance, but the emphasis is more on immersive sound than aesthetics.

Battery and Rechargeability

Both hearing aids offer rechargeable battery options, ensuring all-day performance without the need to change batteries frequently. The “R” in Lumity L90 R indicates its rechargeable nature. It offers a full day of hearing, even with streaming.

Infinio Sphere i90 also comes with advanced rechargeable technology, promising comparable battery life and fast charging capabilities.

Connectivity and App Support

Phonak has ensured that both models support universal Bluetooth connectivity, which means they can easily connect to smartphones (Android and iOS), tablets, and even TVs.

Both models work with the myPhonak app, allowing users to customise settings, track hearing aid usage, and access remote support. Infinio Sphere i90 may come with some upgraded remote control options tailored to immersive listening preferences, while Lumity L90 R is more tuned toward conversational enhancement features.

Conclusion: Which One to Choose?

Choose Phonak Infinio Sphere i90 if you're looking for a more natural, immersive hearing experience with balanced sound awareness in every environment. It’s great for users who want to stay connected to ambient sounds without missing out on key conversations.

Choose Phonak Lumity L90 R if your top priority is clear speech and ease of communication in noisy places. It’s best suited for socially active users who attend meetings, social gatherings, or frequently navigate noisy environments.

Both are excellent choices, and the final decision depends on your lifestyle and hearing preferences. For personalised advice, consult an expert at USA Hearing Experts.
