Oticon Own SI 4 Hearing Aids Overview
In March 2025, Oticon introduced their latest custom hearing aids, the Oticon Own SI 4, powered by the advanced Sirius processing chip, originally seen in Oticon Intent, and featuring the trusted BrainHearing technology, all in a more compact design. Available in two discreet in-ear styles, the Oticon Own SI 4 offers the introductory level of technology, delivering some of the features available in the range.
How does BrainHearing technology help you? We hear with our brain, not just our ears and by tapping into more natural and beneficial brain support, using this technology, your brain can access a bigger soundscape. This is simply because it has more information to work with so it can ultimately perform better. This means more sense of sound with less effort needed.
Why choose Oticon Own SI 4 hearing aids?
Better conversations: Great speech clarity allows you to have more focus and control in conversations.
More comfortable: Designed to fit snuggly in your own unique ear shape, you will experience all-day comfort.
Made to endure: A custom design you can rely on with advanced water and dust resistance.
Oticon Own SI 4’s MoreSound Intelligence 3.0
MoreSound Intelligence 3.0 is a technology that makes it super easy for wearers to enjoy, follow, and get involved in conversations. It carefully scans and analyses the surrounding soundscape, then sorts the noises around you. It uses the all-new on-board DNN 2.0 to process and highlight the differences between the sounds it picks up.
This technology delivers a full, more balanced, and clearer sound experience than ever, no matter the situation. Plus, with its 4D sensors, it effortlessly adjusts to your specific listening needs, offering tailored support based on the environment and what you’re trying to hear, making speech comprehension much better.
Oticon Own SI 4’s MoreSound Amplifier 3.0
The MoreSound Amplifier 3.0 offers wearers precise and balanced amplification across a frequency range from 80 Hz to 10,000 Hz. This gives you a more immersive sound experience, with a richer, fuller representation of your surroundings.
Thanks to the cleaner, clearer sound input from MoreSound Intelligence 3.0, the MoreSound Amplifier 3.0 has a unique foundation for boosting a wide range of sounds, tailored to each wearer’s needs. This means it can deliver all the important sounds across the full frequency range, catering to every fitting.
Oticon Own SI 4’s MoreSound Optimiser
MoreSound Optimiser actively detects and prevents feedback without reducing gain. It’s one-of-a-kind, patented Spectro Temporal Modulation tech creates a breaker signal that stops feedback before it even starts. This clever feature helps prevent any invisible loss of gain, ensuring you get the right amount of gain all day long. So, you’ll always receive the gain you’re meant to have.
The result? Better access to speech details, a more natural sound, increased comfort, and improved speech understanding, even in the busiest, most dynamic environments.
Oticon Own SI 4 hearing aid models and colours
Oticon Own SI 4 IIC: Invisible-in-the-Canal (IIC) custom hearing aids sit deep within the ear canal, offering the perfect blend of discreet design, exceptional sound quality, and all-day comfort. Featuring BrainHearing technology, they work with your brain’s natural process of interpreting sound, enhancing your listening experience.
Available in colours beige, light brown, medium brown, dark brown, black, transparent, transparent blue, and transparent red.
Oticon Own SI 4 CIC: Completely-in-the-Canal (CIC) custom hearing aids sit snugly inside the ear canal, offering a discreet design, top-notch sound quality, and comfort throughout the day. Equipped with BrainHearing technology, they help your brain process sound naturally, enhancing your overall listening experience.
Available in colours beige, light brown, medium brown, dark brown, and black. Both models use size 10 disposable batteries and have hearing loss levels that range from mild to severe.
What features do you lose when comparing Oticon Own SI 4 with 1?: You do not benefit from the sensor technology, and this performance level has less spatial balance and noise suppression, too. It’s worth considering either performance levels 1 or 2 if you find yourself in noisy environments often, as these levels will give you premium speech understanding in noise.
