Oticon Own SI 2 Hearing Aids

Introduction to the Oticon Own SI 2 Hearing Aids

The Oticon Own SI 2 is a high-performing custom in-the-ear hearing aid designed to deliver outstanding sound clarity in a sleek, discreet form. Built on Oticon’s new Sirius™ platform, the SI 2 brings advanced features inspired by the brain’s natural hearing process, offering a tailored, comfortable experience that fits seamlessly into your everyday life. Whether you're navigating busy streets, chatting with family, or relaxing at home, the Own SI 2 ensures you stay connected to the sounds that matter most, all without compromising on comfort or style.

Smart Hearing Support in a Subtle Design

The Oticon Own SI 2 strikes a balance between discreet design and intelligent sound processing, using Oticon’s BrainHearing™ technology and Deep Neural Network 2.0 to enhance speech understanding and reduce background noise. As the second-highest performance level in the Own SI range, the SI 2 is perfect for those who want reliable support in most listening situations, without needing the absolute top-tier configuration.

Key Features of Oticon Own SI 2

Sirius™ Platform with DNN 2.0

Like the Oticon Own SI 1, the Own SI 2 uses Oticon’s latest sound processing chip paired with Deep Neural Network 2.0, trained on 12 million sound scenes. It helps separate speech from noise more effectively, making conversations easier to follow, even in moderately noisy environments.

Sudden Sound Stabiliser

The SI 2 softens sudden, loud sounds while preserving speech clarity. Though slightly less configurable than the SI 1, it still offers excellent protection from jarring environmental noises, contributing to a smoother listening experience.

BrainHearing™ Technology

Oticon’s unique BrainHearing™ system supports how your brain naturally makes sense of sound, improving listening comfort and speech comprehension across a range of environments.

Discreet Custom Fit: IIC or CIC Options

The Own SI 2 is available in two nearly invisible styles:

• IIC (Invisible-in-Canal) – ultra-small and fully hidden
• CIC (Completely-in-Canal) – still discreet, with more amplification power

Durable and Reliable

The SI 2 carries an IP68 rating, protecting it against dust and moisture. It’s built for daily wear, whether you’re indoors, outdoors, or on the go.

Battery Life

The hearing aid uses disposable size 10 or 312 batteries (depending on the style), giving you several days of reliable power with no need for charging cables or docks—great for those who want simple day-to-day maintenance.

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

Limitations 

To maintain its small size, the SI 2 does not support Bluetooth streaming, app-based control, or rechargeable batteries—features found in larger custom or behind-the-ear models. However, it prioritises comfort, invisibility, and excellent sound quality where it matters most.

The difference between Oticon own SI 1 and Oticon own SI 2

The Oticon Own SI 1 and SI 2 are both advanced custom in-the-ear hearing aids powered by Oticon’s latest BrainHearing™ technology, but they differ in performance levels and features. The SI 1 is the top-tier model and offers more powerful neural noise suppression (up to 12 dB in difficult environments) compared to the SI 2’s 10 dB.

It also supports a wider bandwidth of up to 10 kHz, delivering clearer, more detailed sound, while the SI 2 is limited to 8 kHz. Additionally, the SI 1 includes more Sudden Sound Stabilizer settings, as well as premium features like Clear Dynamics and full Better-Ear Priority for improved spatial awareness and sound precision—features either limited or absent in the SI 2. These differences make the SI 1 better suited for users who spend time in complex or noisy environments and want the highest level of sound clarity and control.
