Hearing technology continues to advance at incredible speed, giving users access to smarter, more convenient, and more intuitive solutions than ever before.
At Hampstead Hearing, we are proud to introduce two of the most exciting developments in modern hearing care: the Oticon Zeal and the Phonak Infinio Ultra Sphere.
These two next-generation hearing aids approach innovation from different angles, offering exceptional clarity, connectivity, and comfort for day-to-day listening. Below, we explore what makes each device stand out and which users they are best suited to.
The Oticon Zeal – convenience, connectivity, and discretion redesigned Oticon’s latest release marks a major step forward for in-the-ear hearing aid technology. The Oticon Zeal bridges the gap between traditional receiver-in-canal devices and fully custom in-the-ear models, combining multiple highly requested features into a single discreet, ready-to-wear hearing aid.
Often described as “the hearing aid many have long asked for”, the Oticon Zeal offers simplicity, performance, and modern design in a compact and user-friendly format.
A modern hearing aid ready straight from the box The Oticon Zeal is rechargeable, discreet, and designed to be worn immediately without the need for impressions. Key features include:
Bluetooth connectivity for phone calls and audio streaming.
Personalised hearing correction tailored through professional programming.
A compact, in-the-ear design that blends convenience with performance.
While some of these capabilities exist individually in other models, the Zeal is the first in-the-ear device to bring them all together.
A discreet modular design that adapts to you One of the most impressive features of the Oticon Zeal is its hybrid modular design. Instead of requiring full customisation, the Zeal uses:
Medical-grade silicone domes for most users.
Optional custom tips for those who need an enhanced personalised fit.
Only around 30% of users are expected to need custom tips, making the Zeal one of the most accessible in-the-ear hearing aids available.
The device also includes a multi-purpose retention antenna which:
Enables Bluetooth streaming.
Acts as a retention arm for added stability.
Works as an extraction cord.
Naturally moulds to the shape of the ear over time for improved comfort.
This clever design supports everyday wear while keeping the device discreet and secure.
Rechargeable power for life on the go The Oticon Zeal provides:
A full day of listening on a single charge.
A fast recharge time of just a few hours.
A charger with a built-in lithium-ion battery for powering up anywhere.
Whether travelling, working long days, or simply avoiding the worry of battery changes, this rechargeable design offers unmatched convenience.
Advanced sound and AI-powered performance Built on Oticon’s latest platform, the Zeal uses artificial intelligence and motion sensors to enhance speech understanding in challenging listening environments. It automatically adapts to different surroundings by managing background noise in real time.
Through the Oticon Companion app , users can:
Adjust volume, bass, treble, and programmes.
Stream calls, music, and media directly to their hearing aids.
Fine-tune settings quickly from their smartphone.
Who is the Oticon Zeal ideal for? Hampstead Hearing recommends the Oticon Zeal for:
Current in-the-ear users who want Bluetooth connectivity and rechargeable performance.
People who prefer discreet modern designs without sacrificing sound quality.
Receiver-in-canal wearers who are looking for a bridge between styles.
New users who like the feel of earbuds but require professional hearing correction.
Suitability is always determined through a complete hearing assessment to ensure a perfect match for your hearing, anatomy, and lifestyle.

Phonak Infinio Ultra Sphere – redefining performance and connectivity Phonak has long been recognised for its industry-leading innovation, and the new Infinio Ultra hearing aid represents a significant step forward in AI-powered sound processing and Bluetooth performance. Following the success of the Infinio Sphere, the Ultra introduces smarter, faster, and more efficient technology.
Advanced AI sound processing At the heart of the Infinio Ultra is the upgraded DeepSonic processor, trained on nearly 400 million real-world sound samples. This deep neural network allows the hearing aids to separate speech from noise with exceptional accuracy.
With the transition from AutoSense 6.0 to AutoSense 7.0 , environmental recognition is now up to 24 percent more accurate. This means:
Clearer speech in busy settings.
Smoother transitions between environments.
Reduced listening fatigue throughout the day.
The Ultra is particularly well-suited to people who rely on excellent performance in challenging surroundings, enjoy music and entertainment, or want a set-and-forget experience that adjusts automatically.
Smarter, more efficient, and longer lasting Phonak has improved both sound performance and battery life. The redesigned AI system delivers:
Up to 10.2 dB better signal-to-noise ratio for sharper speech clarity.
30% lower power consumption.
Up to 56 hours of use on a single charge, even with frequent streaming.
This marks a significant leap forward, providing users with increased confidence and reliability throughout the day.
World-class Bluetooth connectivity Phonak continues to lead in Bluetooth capability. The Infinio Ultra hearing aid features:
Universal Bluetooth pairing across a wide range of devices.
Connect up to eight devices simultaneously, with two active at a time.
A simpler, faster pairing process that improves on previous Phonak systems.
While Auracast is not yet activated, the Ultra still offers some of the strongest Bluetooth performance available.
Phonak has also released the more discreet Infinio Ultra R, which includes the same advanced processing in a smaller design.
Free upgrade for existing Sphere hearing aid users If you recently purchased the Phonak Infinio Sphere, you can upgrade to the new Ultra features at no additional cost. The process takes one appointment and approximately seven minutes.
