Oticon Zeal 1

The Oticon Zeal 1 introduces something genuinely new in the hearing aid world — the first In-the-Ear hearing aid that doesn’t force you to compromise on the features that matter.

For years, choosing a discreet hearing aid meant accepting limitations: no rechargeable batteries, basic sound processing, limited connectivity. The Zeal 1 eliminates all these compromises in one clever package.

Currently available at the premium technology level, it isn’t just a smaller version of existing tech with features stripped out to fit the space. It’s a complete rethink of what an In-the-Ear hearing aid can be — using the same AI sound processing found in Oticon’s Intent range, while maintaining genuine discretion.

If you’ve been putting off getting hearing help due to visibility concerns or have been frustrated by in-the-ear aids that couldn’t keep up with your lifestyle, the Zeal 1 changes the equation entirely.

Who should consider the Oticon Zeal 1?

The Zeal 1 is ideal if you:

• Want discreet hearing aids without sacrificing modern features

• Live an active, connected lifestyle and need seamless smartphone integration

• Prefer an In-the-Ear design but still want premium AI sound quality

• Have worn Behind-the-Ear aids but want something smaller and more discreet

• Simply want the most advanced In-the-Ear technology available today

Oticon Zeal 1 Feature Highlights

BrainHearing Technology with Second-Generation AI

The Zeal 1 uses Oticon’s BrainHearing philosophy, which supports how your brain naturally processes sound rather than simply amplifying everything.

Powered by DNN 2.0 (Deep Neural Network) — trained on over 12 million real-world sound scenes — the system recognises and adapts to your listening environment, automatically distinguishing speech from background noise.

This is the same advanced technology used in Oticon’s flagship Intent range — not a scaled-down version.

Key components include:

• MoreSound Intelligence 3.0 — enhances clarity and speech understanding in all soundscapes

• MoreSound Amplifier 3.0 — delivers rich, balanced sound across the full frequency range

Innovative Encapsulation Technology

The Zeal 1’s small size is made possible by innovative encapsulation — similar to medical-grade engineering used in pacemakers.

This sealed design provides:

• IP68-rated moisture and dust resistance

• Greater protection against corrosion

• A compact and durable structure

This means fewer issues with reliability and maintenance — a leap forward in hearing aid engineering.

Connectivity That Works

Bluetooth connectivity in hearing aids used to be hit-and-miss. The Zeal 1 fixes that with the latest Bluetooth LE Audio standard, offering higher sound quality and stable streaming directly to both ears.

Additional connectivity highlights:

• Google Fast Pair — effortless pairing for Android users, with automatic device recognition across linked accounts

• Auracast-ready — future-proofed for next-gen public audio sharing systems

• Hands-free streaming — enjoy music, calls, and TV audio without dropouts

In short, Zeal 1 integrates smoothly into your connected life.

All-Day Rechargeable Power

The Zeal 1’s lithium-ion battery provides:

• Up to 20 hours of use (including streaming)

• Quick charging:

  • 15 minutes = 4 hours of use

  • 30 minutes = 8 hours

  • 2 hours = full charge

The SmartCharger includes a built-in power bank offering three extra full charges — perfect for travel or weekends away.

Just dock your hearing aids overnight and wake up ready to go.

Same-Day Fitting

Traditional custom In-the-Ear aids often require ear impressions and long wait times. The Zeal 1 changes that with a modular hybrid design that allows:

• Same-day fitting using medical-grade silicone domes or custom tips

• Custom micromoulds as an option for complex ear shapes

That means you can walk out of your appointment wearing your new hearing aids instead of waiting weeks.

Additional Features

• SuddenSound Stabiliser: Manages sudden loud sounds while preserving important details

• Wind and Handling Stabiliser: Reduces wind and handling noise 500 times per second without affecting clarity

• Multi-purpose retention antenna: Functions as Bluetooth connector, extraction cord, and retention device — adapting to your ear’s shape over time

• Tap control: Adjust settings or answer calls with a simple double tap

Compatible Oticon Accessories

• TV Adapter 3.0: Streams stereo sound directly from your TV

• ConnectClip: Enables hands-free calling and remote microphone functionality

• Easy LE Adapter: Adds streaming from USB-C devices without LE Audio support

• Remote Control 3.0: Adjust volume and programmes discreetly

• Phone Adapter 2.0: Connects landline phones to the ConnectClip

• Companion App: Free smartphone app for control, settings, and fine-tuning

These accessories are optional — the Zeal 1 performs exceptionally well even on its own.
