Oticon Own SI 3 Hearing Aids

Introduction to the Oticon Own SI 3 Hearing Aids

The Oticon Own SI 3 is a mid-range invisible hearing aid that combines reliable performance, discreet custom-fit design, and proven BrainHearing™ technology. Built on the cutting-edge Sirius™ platform, it offers intelligent sound processing, clear speech understanding, and all-day comfort, wrapped in a subtle, in-the-ear device that fits seamlessly into your life.

If you're new to hearing aids or looking for a balance between advanced features and affordability, the Oticon Own SI 3 offers a powerful hearing solution in a small and nearly invisible design.

Smart Hearing, Made Simple

Powered by Oticon’s BrainHearing™ approach, the Own SI 3 supports how your brain naturally interprets sound. It reduces listening effort in everyday situations while still delivering a clear and natural sound experience. As a mid-level model in the Own SI range, SI 3 includes many of Oticon’s most valuable features, making it a strong choice for people who want discreet hearing support with modern processing.

Key Features of Oticon Own SI 3

Sirius™ Platform with DNN 2.0

The SI 3 uses the same Sirius™ chip as the higher-end models, giving you advanced sound processing and improved speech detection. While it doesn’t offer quite as much customisation as the SI 1, it still uses Oticon’s Deep Neural Network (DNN 2.0)—trained on millions of real-world sound environments—to help distinguish speech from background noise and enhance the sounds you care about.

Sudden Sound Stabiliser

The Own SI 3 includes Oticon’s Sudden Sound Stabiliser, which smooths out loud or sharp noises for a more comfortable listening experience. Although it offers fewer configurations than the SI 1, it still provides effective protection from startling sound changes.

BrainHearing™ Technology

Just like the higher-tier models, the SI 3 is built with BrainHearing™ support, helping you process sound more easily and understand speech more clearly, especially in day-to-day environments like shops, cafés, or meetings.

Discreet Custom Styles

The Own SI 3 is available in two tiny in-the-ear options:
• IIC (Invisible-in-Canal) – ultra-discreet, custom-moulded to fit deep in your ear canal
• CIC(Completely-in-Canal) – slightly larger, with additional features for moderate hearing loss

Durable & Everyday-Ready

With an IP68 rating, the SI 3 is resistant to moisture, dust, and sweat, making it suitable for daily wear in all kinds of environments—from rainy walks to busy workdays.

Battery Life & Maintenance

The SI 3 uses size 10 or 312 disposable batteries, depending on the selected style. These compact batteries are easy to replace and offer several days of use, making them a great choice for users who prefer low-maintenance hearing support.

Available in colours beige, light brown, medium brown, dark brown, and black.

Limitations 

To maintain its discreet and ultra-compact form, the Oticon Own SI 3 does not include Bluetooth streaming, app control, or rechargeability. These are features found in larger in-ear or behind-the-ear devices. Instead, the SI 3 focuses on delivering dependable, invisible hearing support in a comfortable, user-friendly format.

The difference between Oticon own SI 1 and Oticon own SI 3

The Oticon Own SI 1 and SI 3 both deliver discreet, custom-moulded hearing support built on Oticon’s powerful Sirius™ platform, but they differ in performance and feature depth. The SI 1 is the top-tier model, offering maximum neural noise suppression, a wider 10 kHz bandwidth for richer sound detail, and advanced features like Clear Dynamics and full Better-Ear Priority for superior sound clarity in complex environments.

In contrast, the SI 3 provides a solid mid-level experience, still using Deep Neural Network 2.0 and BrainHearing™ technology, but with slightly reduced speech enhancement and fewer customisation options. While both models offer invisible styles and IP68 durability, the SI 1 is best for those who need premium performance in very challenging listening environments, whereas the SI 3 is ideal for users who want dependable, high-quality hearing support without the extra cost of top-tier features.
