Does this sound familiar?

If hearing has started to hold you back,
you're not alone

  • "Sorry, can you say that again?" — for the third time in one conversation.

  • The telly is up so loud the family keeps asking you to turn it down.

  • You smile and nod in groups because you've missed half of what was said.

  • You've put off doing anything because clinic hearing aids cost a small fortune.

The STZ Harmony was made for exactly this — clearer hearing for everyday life, at a price that doesn't sting.

  • 1 · Connect & pair

    Pair with the free Steezia app and your phone over Bluetooth.

  • 2 · Take a quick hearing check

    The app builds a sound profile around your hearing.

  • 3 · Stream & adjust

Quick honesty check — is it right for you?

The STZ Harmony is our behind-the-ear, Bluetooth model — built for mild to moderate hearing difficulty, for people who want streaming and app self-fitting. Prefer the most discreet, in-ear option? Go for the Minitone Pro (app, in-canal) or the Minitone (simplest) or the Minitone XS (Smallest). Not fussed about Bluetooth? The in-ear Minitone range costs a little less.

Please note: it's a self-fit aid, not a substitute for a professional hearing assessment. See a GP or audiologist first if your hearing loss is sudden, one-sided, or comes with pain, discharge or dizziness.

You've got questions

We've got answers
Does the STZ Harmony stream phone calls and music?

Yes. Bluetooth is built in, so you can take phone calls and play music straight through your hearing aids. This is our streaming model.
Will people see it? Is it discreet?

It sits behind the ear with a thin wire into the canal, so it's more visible than our in-ear Minitone range — but it's lightweight, low-profile and comes in neutral colours. If the most invisible option matters most, look at the Minitone XS.
What colours does it come in?

Beige and Silver Grey — choose your colour above before adding to cart.
Are these just amplifiers?

No. It's a self-fit hearing aid with a 16-channel digital chip, noise reduction and feedback control designed to make speech clearer — not simply make everything louder — and the app lets you personalise the sound to your hearing.
Do I need a hearing test or an appointment?

No test or appointment is needed to buy. It's self-fit, and the app includes a hearing check to help set your starting point. Please see a GP or audiologist first if your hearing loss is sudden, one-sided, or comes with pain, discharge or dizziness.
What if the sound feels too loud at first?

That's common while your ears adjust. Start at a lower volume, complete the app hearing check, and try a different ear tip for a better seal — it settles for most people within a few days.
What if I hear whistling?

Whistling is usually down to fit — the ear tip size, wax build-up, or the aid not sitting snugly. Try a different tip, clean the wax guard, and reinsert securely. The included feedback control is designed to help reduce it, and our team can help if it persists.
Will they fit my ears?

They come with several sizes of soft silicone tips to suit most ears. If you can't get a comfortable, secure fit, you're covered by the 30-day trial.
How long does the battery last?

Up to around 16 hours on a full charge, with extra top-ups from the charging case during the day. A full charge takes roughly a couple of hours.
What's your return policy?

Every order comes with a 30-day risk-free trial. Not right for you? Contact us within 30 days of delivery for a return and full refund. Details on our Refund Policy page.
