Why patients choose the Zeal
Hearing help that nobody sees
Virtually invisible
Sits deep in the ear canal — from the side, from the front, it simply isn’t seen.
Remarkably natural sound
Built on Oticon’s BrainHearing approach — sound that feels effortless rather than processed.
Control from your phone
Adjust volume and settings discreetly through the Oticon Companion app.
Rechargeable — all-day power
No fiddly disposable batteries. Charge overnight, wear all day, and the portable SmartCharger tops you up on the go.
Streams calls, music & TV
Bluetooth® Low Energy streaming from your phone, TV or tablet, plus Auracast™ for public venues — all from a hearing aid nobody can see.
Fitted by specialists
Deep-canal fittings need experience — ours are prescription-fitted with real-ear measurement.
One level. No confusing choices.
Zeal 1 — £3,995 a pair
Unusually for a modern hearing aid, the Zeal comes in just one level — Oticon’s best. Adaptive directionality focuses on the speech in front of you, with enhanced comfort in everyday and mildly noisy environments. It is rechargeable, it streams from your phone and TV, and its always-on AI adapts to the room moment to moment. No tech-level decisions, no trade-offs: if invisibility is your priority, this is simply the one.

Client meetings, first impressions, or simply your own business — you want your hearing handled without a single visible clue.
Our recommendation: Zeal — it’s what it was built for
You’d rather forget you’re wearing anything at all — deep-fit acoustics use your own ear’s shape, so sound arrives the way nature intended.
Our recommendation: Zeal — BrainHearing sound, invisible fit
Restaurants and big groups several times a week — worth comparing with our speech-in-noise specialists.
Our recommendation: Compare Zeal with the Phonak Sphere at your assessment
Not sure where you fit? That’s exactly what your £59 assessment is for — and you can trial before you decide.
“The Zeal is for the patient whose first question is “can anyone see it?” — and with this one, the honest answer is no. It’s a lovely, natural-sounding aid. My one honest caveat: if your week is full of loud restaurants and big gatherings, a behind-the-ear aid with stronger noise processing may serve you better — that’s exactly what your trial will tell us.”

Good to know
What is included in the price?
Everything: assessment, deep-canal impressions, prescription fitting with real-ear measurement, all adjustments, a 4-year warranty and 4 years of unlimited aftercare. Price is for a pair — single aids from £798.
Will people be able to see it?
No — the Zeal sits deep in the ear canal and is virtually invisible in normal life. It is the most discreet aid we fit.
Why is there only one technology level?
Oticon built the Zeal at a single, premium specification — so there are no confusing tiers. One level, Oticon’s best invisible technology.
Is the Oticon Zeal rechargeable?
Yes — unlike most invisible hearing aids, the Zeal has a rechargeable battery that lasts all day from an overnight charge, and comes with a portable SmartCharger for extra charges away from a socket.
Does it have Bluetooth?
Yes. The Zeal streams calls, music and TV via Bluetooth® Low Energy from compatible phones, tablets, PCs and TVs, is controlled from the Oticon Companion app, and supports Auracast™ broadcast audio in public venues. Bring your phone to your appointment and we will pair it there.
Is it right for very noisy places?
It handles everyday and mildly noisy environments well. If your week revolves around loud restaurants and big groups, a behind-the-ear aid with stronger noise processing may serve you better — your wear-at-home trial will tell you.
