Oticon Own SI
Oticon Own SI is a custom-moulded in-the-ear hearing aid in IIC and CIC styles, whose always-on on-board Deep Neural Network handles speech clarity and noise reduction inside the device itself. It is fitted by a hørespecialist.
What is Oticon Own SI?
Oticon Own SI is not software: it is a custom-moulded in-the-ear hearing aid, a wearable medical device shaped from an impression of each wearer's own ear. It exists in two styles only, Oticon Own SI IIC (invisible-in-the-canal, seated deep inside the canal) and Oticon Own SI CIC (completely-in-the-canal), catalogued as Custom IIC and Custom CIC.
What earns it a place in an AI directory is where its intelligence sits. Own SI carries an on-board Deep Neural Network that is always active, running inside the shell of the device itself. No phone, no account and no cloud take part in the sound processing. Oticon presents it as DNN 2.0, the second generation of its hearing-aid AI, on the Sirius™ hardware platform, and states that the network was trained on 12 million real-life sound scenes — Oticon's own training material, not recordings taken from the wearer.
The manufacturer gives an engineering reason for putting a neural network in this particular product. A custom device small enough to vanish into the ear canal has room for a single microphone, so there is no dual-microphone system to build directionality with; Oticon argues that an always-on DNN is therefore the best available route to speech clarity and noise reduction on this form factor. The product sits under the company's BrainHearing™ approach, which frames the goal as supporting the brain's natural processing of sound rather than simply making it louder. One named function, the SuddenSound Stabilizer, is described as reaching in-the-ear models for the first time: it detects abrupt sounds, a slamming door being the site's own example, and treats them instantly. Oticon also claims an IP68 rating, presented as the highest possible classification for resistance to water and dust. The commercial pitch is summarised in the manufacturer's own English wording: the discreet size clients want, the audiology they need.
Its limits are as deliberate as its strengths. The first-party product record for both models lists no Bluetooth, no telecoil, no rechargeability, no companion app and no compatible accessories: it runs on a disposable battery and streams nothing. Nor is it sold online — Oticon Own SI is dispensed by a hørespecialist, who takes the ear impression and programmes the device.
What it does
- Runs a second-generation Deep Neural Network (DNN 2.0) on board, permanently active, with nothing for the wearer to switch on or set.
- Processes sound entirely inside the device: no smartphone, no internet connection and no cloud are involved.
- Detects sudden sounds and softens them instantly with the SuddenSound Stabilizer, loud or soft, without making them inaudible.
- Improves speech clarity in every direction around the wearer, a result Oticon documents in its own research brief (Denker & Santurette, 2025).
- Recovers and preserves the faintest parts of speech, according to the manufacturer's claim.
- Sits in a shell moulded on the exact impression of the wearer's ear for retention and comfort across a full day.
- Withstands water and dust at the IP68 rating, which Oticon presents as the highest possible classification.
When to use Oticon Own SI / When not to
A quick filter to help you decide if Oticon Own SI is the right fit.
When to use Oticon Own SI
- Adults with hearing loss who put discretion first: Oticon describes the Own SI IIC as completely invisible in nine ears out of ten, citing its own evidence documentation (Rumley et al., 2022).
- People who regularly wear headsets, hats, hard hats or glasses, a situation the manufacturer highlights as more comfortable with a device that sits entirely inside the ear canal.
- Wearers who want nothing to charge and nothing to pair: Own SI runs on a disposable battery and needs no smartphone to be worn or adjusted.
- Listeners whose difficulty is following conversation and coping with abrupt noises such as a slamming door, which the SuddenSound Stabilizer is presented as addressing.
- Hørespecialister who need to fit a patient asking for a very discreet custom device without stepping down to a lower audiological tier.
When not to use Oticon Own SI
- Anyone who wants to stream calls, music or television straight into their hearing aids: Own SI has no Bluetooth on either model, streaming being reserved for the 2.4 GHz Oticon Own styles.
- Anyone who expects to control or fine-tune their hearing aids from a smartphone: the first-party product record for both models lists no app, and Oticon Companion is not compatible with Own SI.
- Anyone who wants a rechargeable device, or who needs a telecoil to pick up the induction loops installed in auditoriums, churches or stations: Own SI has neither, running on a disposable battery.
- Anyone hoping to buy online or fit themselves: the device requires an impression of the ear and a visit to a hørespecialist.
- Children, and people with severe to profound hearing loss: Oticon steers paediatric fittings towards Oticon Play SI and files its more powerful models in a category separate from in-the-ear devices.
How to use Oticon Own SI
A typical end-to-end flow, from setup to results.
- Optionally start with the site's online hearing test and hearing-loss simulator, which Oticon presents as a starting point and not as a diagnosis.
- Use "Find en hørespecialist" to locate the nearest hearing clinic: there is no online purchase path for the device itself.
- In Denmark, decide which of the two routes the site describes applies to you, the public one through a hospital or an affiliated ENT specialist, or the private one through a private hearing clinic.
- Have the hearing care professional assess your hearing and take an impression of your ear.
- Choose between the IIC and the CIC style, and a colour from the catalogue; the shell is then manufactured to the unique shape of your ears.
- Let the professional programme the fitting with Oticon's fitting software (Genie 2), documented in the site's professional section.
- Wear it with nothing to configure day to day: the DNN is always active, and no smartphone or app is involved at any step.
- On the CIC, use the push-button to change programme and adjust volume; the IIC has no control, only an extraction cord for removal.
- Maintain it by replacing the disposable battery, cleaning the device and changing the wax filter, following the site's care-and-cleaning section and the instructional videos published for Own SI IIC and Own SI CIC.
Pros & Cons
Pros
- The AI works with no connection, no smartphone and no account: all the processing happens inside the hearing aid.
- It is active permanently and at every tier of the range, with no intervention asked of the wearer.
- Discretion is the product's strongest claim: Oticon describes the IIC as invisible in nine ears out of ten, citing Rumley et al. (2022).
- Custom comfort: the shell is moulded on the anatomy of each individual ear rather than fitted from stock sizes.
- IP68 is claimed explicitly for this product, at the highest level of water and dust resistance.
- Sudden sounds get dedicated treatment through the SuddenSound Stabilizer, a function new to this form factor.
- Oticon publishes evidence for its claims: a research brief on Own SI is downloadable from the professional page.
Cons
- No price is published anywhere: neither the product pages, nor any other page collected, nor the 342 URLs of the site's sitemap show an amount for Own SI, and the site has no pricing page.
- No connectivity at all: no Bluetooth, no streaming, no hands-free calling, no Auracast and no ASHA, all of which the site reserves for the 2.4 GHz styles of the range.
- No companion app: Oticon Companion appears on the Own SI pages as part of a catalogue block, but the first-party product record for both models lists no app.
- No telecoil and no rechargeable battery, which means no access to public induction loops and a disposable cell to replace regularly.
- The site publishes no quantified audiological figure for this product: no gain, no fitting range and no noise reduction expressed in decibels.
- The product cannot be obtained without a hearing care professional, and the site announces neither a free trial nor a direct purchase route.
- The evidence cited for the headline claims consists of the manufacturer's own documents (Oticon Research Brief, Oticon Whitepaper) rather than independent publications.
Pricing & Plans
No price is published for this product. Neither the Oticon Own SI pages, nor any of the other pages collected, nor the 342 URLs of the site's sitemap carry an amount, and the site has no pricing page at all. The only price-adjacent statement, on Oticon's AI page, is that the company offers hearing aids with AI "i forskellige prisklasser og modeller" — in different price ranges and models — with no figure attached. This is an established non-publication rather than a gap in research: Own SI is a custom device dispensed by a hearing care professional, and the site prices no part of that journey. For Denmark it distinguishes two routes without attaching an amount to either: a public route, in which devices are supplied by a hospital or an affiliated ENT specialist at no cost to the patient, and a private route, in which the device is bought from a private hearing clinic. The first of those is a feature of the Danish healthcare system, not a commercial offer from Oticon. Consequently no free plan, no free trial and no starting price can be stated for Oticon Own SI, and no pricing model can be inferred.
Data, GDPR & hosting
A consolidated view of how Oticon Own SI handles your data.
GDPR overview
Implementation is explicit and article-level. The privacy policy claims controller status under Article 4(7) and legitimate interest under Article 6(1)(f), with explicit consent for e-mail marketing. Transfers to Demant group affiliates and to suppliers outside the EU/EEA are announced where necessary, under the European Commission's standard contractual clauses, with a stated commitment to appropriate technical and organisational measures. Data subject rights are enumerated, and the Danish supervisory authority is named: Datatilsynet, with a route to complain in one's country of residence. The site states it is neither intended for nor designed to collect data from children under 13. The main policy is dated December 2025, but the page stacks older ones (19 December 2019, August 2022) covering other Oticon services. No DPO is named, no Article 27 representative is designated (consistent with an EU-established publisher), and no DPA is published.
Who owns the data?
Oticon Denmark A/S, Kongebakken 9, 2765 Smørum, is named in the privacy policy as the data controller within the meaning of Article 4(7) GDPR, reachable at privacy@demant.com. What it controls is the website and Oticon's online services: the contact form and chat, the accessory webshop, battery and consumable orders, MyOticon, RemoteCare and the company's social media pages. The document describes no processing of data by the Own SI device itself, which has no documented connectivity. Two points deserve flagging: another section of the same policy states that "we" and "our" mean Oticon A/S, and the Danish CPR number is collected for consumable orders under an arrangement with Danish regions and municipalities.
Reuse rights
The collected documents describe what Oticon does with personal data; they grant the visitor no right to reuse data of Oticon's. Processing rests on legitimate interest (Article 6(1)(f)) for operating and providing the services, and on explicit consent for e-mail marketing. The purposes listed are answering enquiries and appointment requests, handling battery and consumable orders, improving the site, measuring audience and direct marketing. Data may be shared with affiliated Demant group companies and with suppliers handling customer relations, call centres, marketing campaigns (Facebook Custom Audiences and Lookalikes are named by name), logistics and storage; the policy states those suppliers are not permitted to keep or use the data for other purposes and are bound to security and confidentiality. Only categories of suppliers are described, and no named sub-processor list is published. On AI training, the documents are silent: they never mention customer data being used to train a model, and the only training they describe is the DNN's 12 million real-life sound scenes, which are Oticon's own material. As data subject rights, the policy lists access, rectification, erasure, restriction, portability and objection. Separately, the disclaimer page states that some visual content on the site may have been generated or enhanced by AI under the Demant group's internal guidelines, which concerns the site's illustrations, not the product and not user data.
Data retention & training
Hosting summary
The site does not publish where data is hosted: no country, no region and no infrastructure provider is named on any of the pages collected, which is why the hosting country and region fields are left empty. What the privacy policy does announce is a different thing and should not be read as a hosting location: personal data may be shared with Demant group companies and with suppliers located outside the EU/EEA where necessary, under the European Commission's standard contractual clauses and with a stated commitment to appropriate technical and organisational measures. A transfer is not a place of storage. One technical observation concerns the delivery of the website rather than the storage of personal data: the apex oticon.dk redirects to www.oticon.dk, whose resolved IP address (64.239.109.1) geolocates to the United States on Amazon's AS16509, with an anycast indication — an edge node, not the country of a single server, and not a statement about where personal data lives. Finally, the Own SI device has no documented connectivity, so the site describes no transmission of data from the hearing aid to any server.
Things to keep in mind
Risks and trade-offs to weigh before adopting Oticon Own SI.
- Own SI is a medical device, and the site says so itself: its content replaces neither a diagnosis nor the advice of a hørespecialist. Nothing you read about it online, here included, substitutes for a hearing assessment.
- Expect no connectivity whatsoever. Anyone buying it to hear the television, take phone calls hands-free or use a venue's induction loop will be disappointed: those uses belong to other styles of the range, not to this one.
- No price is published anywhere on the site, and the device cannot be obtained without an appointment, an ear impression and a professional fitting. Budget and lead time both have to be established off-site.
- The Oticon Companion block and the accessory list shown on the Own SI pages — chargers, ConnectClip, TV Adapter, EduMic — are a generic catalogue block. The first-party product record for both models lists no accessories and no app, so none of that hardware applies here.
- The same pages describe seven other Oticon products (Reveal, CROS RE, Zeal, Intent, Verit, Real and More). The "Dual AI" belongs to Reveal and CROS RE, the "4D" sensors to Intent and the Polaris™ platform to the other Own models; Own SI runs DNN 2.0 on Sirius™, and none of those other technologies should be read onto it.
- The privacy policy covers the website and Oticon's online services — contact form, webshop, MyOticon, RemoteCare, social media pages — and describes no processing of data by the Own SI device itself. The EU Data Act page is in the same position: it describes access to technical device data only when devices are used with the app, which Own SI is not.
- The site contradicts itself on the legal entity, naming Oticon Denmark A/S in the disclaimer, the contact page and the privacy policy, but Oticon A/S in the cookie policy, the product record's head office entry, the domain registration and the trademark ownership. The heritage narrative and the headcount and country figures on the about page describe Oticon and the Demant group, not this product.
Setup & Integrations
Technical difficulty
There is no technical setup for the wearer: no account, no pairing, no app and no updates. The difficulty is clinical rather than technical: an appointment with a hørespecialist, an impression of the ear and custom manufacture, with the fitting programmed by the professional in Oticon's fitting software (Genie 2). The site publishes no manufacturing or delivery time. Day to day, use comes down to replacing the disposable battery, cleaning the device and changing the wax filter, with instructional videos published for both models. The CIC has a push-button for programme and volume; the IIC has none.

Should you pick Oticon Own SI?
Oticon Own SI earns its place in a directory of AI tools for an unusual reason: its intelligence never leaves the device. The Deep Neural Network runs inside a shell moulded to one ear canal, with no phone, no account, no cloud and no connection of any kind. Oticon justifies that choice technically rather than rhetorically: a custom device this small has room for one microphone, so there is no dual-microphone system to build directionality with, and the manufacturer argues an always-on DNN is the best remaining route to speech clarity and noise reduction.
The trade-off is uncompromising and worth stating plainly. To disappear into the ear canal, Own SI gives up everything connectivity brings: no Bluetooth, no streaming, no companion app, no telecoil, no rechargeable battery. Anyone who wants hearing aids that double as earphones should look at another style in the range; anyone whose first priority is that nobody notices them is exactly the reader this product was designed for.
Two caveats deserve attention. First, the evidence behind the headline claims — the invisibility figure, the speech-clarity result — comes from Oticon's own research documents rather than independent publications. The claims are precise and referenced, but they are the manufacturer's. Second, nothing about cost is published: no page on the site carries an amount for this product. Evaluation happens at a hørespecialist, who takes the ear impression and programmes the device, and for Denmark the site distinguishes a public route from a private one without pricing either. The publisher, Oticon Denmark A/S, states that Oticon is part of the Demant group.
Read as an AI product, Own SI is a clean demonstration of on-device machine learning doing one job continuously and invisibly. Read as a hearing aid, it is a deliberate bet on discretion.
