Is it right for you?
A good fit if
- You find conversations or the TV harder to follow in everyday settings
- You want a discreet, completely in the canal fit
- You prefer simple controls with no app, no Bluetooth and no smartphone
- You want a practical, lower-cost option for everyday listening
Probably not right if
- You need or expect Bluetooth. These do not have it
- You have severe hearing difficulty, or hearing that differs a lot between ears
- You have small or narrow ear canals
- You have a medical concern about your hearing. Please speak to your GP or an audiologist
- You have reduced dexterity. The amplifiers are very small and need careful handling
If you notice a sudden change in your hearing, hearing change in one ear only, pain, ringing or dizziness, please speak to your GP or NHS 111 before using any amplifier.
Getting started
- Charge the case and amplifiers for 10 to 12 hours before first use
- Start with a single ear tip, which is usually the most comfortable. If it will not stay in place or you hear whistling, move up one size or try a double tip
- Place the amplifier gently in your ear and seat it a little deeper if it whistles
- Short press the button for volume and double press for the listening mode. Start at a low volume and build up gradually
Your first week: Most people take a few days to adjust. Your own voice can sound louder at first. Start at a lower volume and build up wear time gradually over the first week. If you hear whistling, try a different ear tip before turning the volume up.

Questions, delivery and safety
Frequently asked questions
Are these hearing amplifiers medical hearing aids?
No. They are personal sound amplifiers designed to enhance everyday listening clarity. It is not a medical hearing aid and is not intended to diagnose, treat, or correct hearing loss.
What is the difference between a hearing aid and a hearing amplifier in the UK?
A hearing aid is a regulated medical device, usually prescribed after a clinical hearing assessment. A hearing amplifier (personal sound amplifier) is a consumer product that makes everyday sounds louder for general listening. The Cantara Micro is a personal sound amplifier. It does not require a prescription and is not a substitute for clinical hearing correction. It is not for severe hearing difficulty or for hearing that differs a lot between ears.
How long does the battery last?
Up to 27 hours per charge at volume level 2, with the charging case taking the total to up to 216 hours. Charge for 10 to 12 hours before first use, then a top-up takes 2 to 3 hours. A blue light means charging and it goes off when charged. Battery life varies with volume level and usage.
Do I need an app or Bluetooth?
No. This model is fully standalone, with no app to download, no Bluetooth and nothing to pair. A single button controls power, the four listening modes and the four volume levels.
What do the four listening modes do?
A short press changes the volume (4 levels) and a double press changes the mode, with a beep to confirm each. The four modes are Intelligent, Outdoor noise reduction, Meeting and General. They help in everyday listening, but these amplifiers lift all nearby sound rather than picking one voice out of noise, so expect less help in very loud places such as busy pubs, a moving car or a windy street.
Where do they work best, and where do they struggle?
They work best for one-to-one conversation, small groups, meetings and the TV. They lift all nearby sound rather than picking one voice out of noise, so expect less help in a busy restaurant, a moving car or a windy street.
How do I choose the right ear tip?
The box includes eight pairs of silicone ear tips from 9 to 15 mm, single and double, including the 12 mm double pair already fitted. If it feels tight or sound seems muffled, go smaller. If it feels loose or sound seems weak, go larger. A good fit directly affects clarity, comfort and feedback. They are not recommended for small or narrow ear canals.
Why do they whistle, and what can I do?
Whistling usually means the ear tip is not sealing, so it is not a fault. Move up one tip size, seat it a little deeper and turn the volume down a step. Set the volume after the tip is seated, because pressing the unit in can nudge the button. If one side stays silent, put it back in the case for a moment and try a different tip. If it is still silent, email our UK team and we will help.
Is it waterproof?
No. It is IPX4 rated, which means it is splash resistant, so sweat and light splashes are fine. It is not waterproof. Do not wear it in the shower, while swimming, or submerge it. Wipe it with the supplied cleaning tool and store it in the case when not in use.
What if they are not right for me?
We understand that hearing amplifiers are a personal product, and not every style or sound will suit everyone straight away. That is why we offer a 30-day home trial. If you decide they are not suitable for you, you can return them within the trial period in line with our returns policy. We do recommend giving them a little time first, as fit, comfort, and everyday sound can take a short period to get used to.
