Types & Technology [Phonak Infinio and Infinio Sphere, Two Years On: The AI Hearing Aid That Fixed Its Own Worst Flaw - For Free](/blogs/types-technology/phonak-infinio-sphere-long-term-review) Almost every hearing aid article you will read is written in the first week after a launch, when nobody has worn the device through a monsoon, a wedding season or a two-year warranty. This one is different. The Phonak Audeo Infinio range launched in August 2024. Two years later we have independent laboratory measurements, more than 1.5 million devices sold, a major free firmware upgrade, and thousands of posts from people who actually live with these hearing aids every day - including some who are very unhappy. The short version is a genuinely interesting story. The flagship Audeo Sphere Infinio arrived with a real technical breakthrough and one serious flaw. Phonak then did something almost unheard of in this industry: instead of selling everyone a new hearing aid, it fixed the flaw with a free firmware update that every existing owner could have. Meanwhile a long-running argument about Bluetooth reliability continues, with credible users on both sides. This article lays out all of it - the measured performance, the documented problems, the fix, and the parts still unresolved. We give information only. We do not tell you which hearing aid to buy. 16 Sep 2026 · 5 min read Types & Technology [Bernafon Revita: The AI Hearing Aid That Listens to the Whole Table](/blogs/types-technology/bernafon-revita-ai-hearing-aid-explained) In August 2026, ReSound launched a flagship hearing aid built on one idea: point a microphone beam at the person you are facing. Within weeks, Bernafon launched Revita - built on very nearly the opposite idea. Bernafon's argument is that real conversation does not sit politely in front of you. It moves. People interrupt from the side. Somebody laughs behind you. So Revita is designed to help you follow voices from the sides as well as from the front, using two artificial-intelligence networks working together. This article sets out only verified, published information: what Revita is, what its two AI networks do, the four technology levels, the one style it launched with, and an important piece of context that no product page mentions - Revita's close relationship to Oticon Reveal, its sister product inside the Demant group. We then place it beside the Phonak Audeo EON Sphere, Signia Pure Charge&Go MaX and ReSound Sensia. We give information only. We do not declare a winner - that decision belongs to you. 10 Sep 2026 · 5 min read Types & Technology [ReSound Sensia: The AI Hearing Aid That Listens Where You Look](/blogs/types-technology/resound-sensia-ai-hearing-aid-explained) Summary Modern hearing aids have become very good at removing noise. What they have never been good at is knowing whose voice you actually want to hear. In a restaurant with four conversations going on, an artificial-intelligence hearing aid will often lock on to the loudest or clearest voice - which may belong to a stranger two tables away. In August 2026, GN Hearing launched ReSound Sensia, a premium hearing aid family built around one simple human idea: you look at the person you want to hear. Sensia combines scene classification, a four-microphone beam pointed where your head is pointed, and deep-neural-network denoising, and it switches all of that on by itself. This article sets out only verified, published information: what Sensia does, how it behaves through a normal day, what the studies actually measured, where the honest limits are, and how it sits beside the other two big launches of 2026 - the Phonak Audeo EON Sphere and the Signia Pure Charge&Go MaX. We give you the information. We do not declare a winner. That decision is yours. 03 Sep 2026 · 5 min read Types & Technology [Four AI Brains in One Ear: What Signia's New Pure Charge&Go MaX Really Delivers](/blogs/types-technology/signia-pure-charge-go-max-review-india) On 24 August 2026, Signia launched **MaX (Multi-adaptive Xperience)**, and the first product on it is the **Pure Charge&Go MaX** [1][2]. Signia calls it the world's first hearing aid platform with **four Deep Neural Networks** working together, under the name Acoustic Intelligence, with a new chip claimed to be 54 times more powerful than the previous generation [1][2]. Is that real, or is it counting numbers to sound impressive? Our honest answer: **there is genuine engineering here, and one upgrade that will quietly matter a great deal in India — but the loudest claim, "four AI brains", is the least meaningful part.** There is also one important catch about Auracast that buyers deserve to know before paying. Here is the full, evidence-checked breakdown. 27 Aug 2026 · 5 min read Types & Technology [Phonak EON Sphere, EON R and CROS EON: Real Innovation or Just Clever Marketing?](/blogs/types-technology/phonak-eon-sphere-eon-r-and-cros-eon-real-innovation-or-just-clever-marketing) On 24 August 2026, Phonak launched EON - a new hearing aid platform with three products: the flagship Audéo EON Sphere, the standard Audéo EON R, and CROS EON R for people who hear from only one ear [1][2][3]. The marketing language is dense: HYPERSONIC, Spheric Speech Clarity 3.0, AutoSense OS AI 8.0, WindBlock 2.0, ANY DIRECTION. So we asked the fair question: is this genuine innovation, or old technology in new packaging? After reading Phonak's own materials and independent coverage, our honest answer is: **this is real engineering — but the breakthrough is in the hardware, not in your hearing.** Phonak itself is not claiming you will hear dramatically better than the previous Sphere. It is claiming you get the same excellent performance in a much smaller, longer-lasting device — and, importantly, at more price levels than before [4]. Here is the detailed, honest breakdown. 26 Aug 2026 · 5 min read Types & Technology [Your Earbuds Are Becoming Hearing Aids](/blogs/types-technology/earbuds-becoming-hearing-aids-india) Something quietly historic just happened in the world of hearing. Samsung's Galaxy Buds have received clearance from the U.S. Food and Drug Administration (FDA) to work as over-the-counter hearing aids - joining Apple, whose AirPods Pro got the same green light in 2024 [1][2][3]. In plain words: the ordinary earbuds in millions of pockets can now run a five-minute hearing test and gently boost sound for adults with mild-to-moderate hearing loss, using NAL-NL2 - the very same fitting formula audiologists use for costly prescription devices [1]. It sounds like a gadget story. But it may be the start of a much bigger shift - especially for India. Here is what is real, what is hype, and what it could mean for your ears. 17 Aug 2026 · 5 min read ## Ready to hear better? Book a free, no-obligation hearing test with our team today.
