Oticon Own Sirius Hearing Aids: What’s new for 2025?
Oticon’s latest update to their Own family of hearing aids has seen a huge AI upgrade, but are they a game-changer or more of the same?
Let’s take a look at what’s new with the Oticon Own SI, what is missing and whether or not this could be the hearing aid that ends your search.
What’s new in the Oticon Own SI?
Oticon’s last custom hearing aid family—the Oticon Own—was released nearly 3 years ago, in August 2022. It included five models, ranging from invisible-in-canal (IIC) to full-shell, all with varying features.
These are custom-made devices, meaning an audiologist takes an impression of your ear so it fits perfectly. However, Oticon has chosen not to replace the entire range this time around. Instead, they’re only updating two models:
- The Invisible-in-Canal (IIC)
- The Completely-in-Canal (CIC)
If you’re looking for In-the-Canal (ITC), In-the-Ear (ITE) half-shell, or ITE full-shell, you’ll need to stick with the 2022 versions for now.
So, what makes the Own S different?
It keeps all the size and style benefits of the previous generation, but there are three standout upgrades:
Artificial Intelligence developments
Noise is the enemy for anyone with hearing loss. Oticon claims to lead the pack in improving speech understanding in noise—thanks to Artificial Intelligence (AI).
Because there’s not enough room for dual microphones (which help with background noise), Oticon turned to AI as a solution.
Oticon’s new Sirius chip is the heart of this device. It houses a deep neural network, essentially giving your hearing aid its own brain.
This AI has been trained using millions of sound samples, including speech, music, traffic and nature sounds. It learns to distinguish speech (what you want to hear) from noise (what you don’t).
Sudden Sound Stabiliser
But, then what about sudden loud noises which aren’t really noises in the traditional sense but something that my patients often complain about, such as the clattering of emptying the dishwasher or door slamming?
Well, Oticon have developed a feature which consistently monitors the incoming sounds using advanced algorithms, and they’ve named it their Sudden Sound Stabiliser. This is designed to smooth out those sudden loud sounds, so instead of getting a jarring spike in volume, the hearing aid is intelligent enough to adjust the amplification and make it more comfortable before it reaches your ear.
Does it actually work?
Well, in Oticon’s studies they found:
- Up to 5.4 dB signal-to-noise ratio improvement
- 2.7 dB clearer speech vs. the 2022 model
In simple terms: speech should sound more distinct, helping you follow conversations in noisy environments and reducing listening fatigue.
Manufacturer claims should always be taken with a grain of salt. For independent testing, check out HearingTracker.com for unbiased results across multiple brands.
Life inside the ear (IP68 Rating)
Let’s face it: the life of an in-ear hearing aid is… rough. They live in a dark, damp, waxy human orifice. Not ideal for electronics.
Thankfully, the Oticon Own S is rated IP68: Water-resistant up to 1.5 meters for 30 minutes, and dust-resistant too.
They’ve achieved this with nano-coating inside and out. Still, I always recommend storing your hearing aids in a drying cup with a drying tablet – no matter the brand.
What’s missing in Oticon Own Sirius?
Now, I don’t just hype the positives—sorry, Oticon—but there are a few downsides you should know:
1. Only for IIC and CIC
The new AI-powered models are only available in the smallest sizes. If you want a larger model, you’re stuck with the older generation—and here’s why that matters…
2. No Bluetooth
No streaming calls, music, TV, or podcasts. If you want Bluetooth, you’ll need to pick an older model.
3. No Telecoil
This would’ve allowed connection to sound sources in theatres, cinemas, and places of worship. It’s not here—likely due to space limitations.
4. No Rechargeable Option
Despite over 90% of my fittings now being rechargeable, Oticon still hasn’t included it in their custom range. You’ll need to change batteries every 3–5 days.
In 2025? That’s a miss. Disposable batteries are just… very 2024.
