The right size, matched from two photos
The standard size suits most adults, but not everyone. AR KI TECH makes sure you get the size that fits you. Add the measurement to your earplugs, photograph your ears online in a few minutes, and our AI compares them against thousands of real ears to find your best size from our range. Your earplugs then arrive in that size within a few business days.

How to photograph your ears
Audiologist-level precision, for 55% less
Custom earplugs from an audiologist cost £150 to £250 per pair, with a clinic appointment and a six-to-eight-week wait. AR KI TECH gives you the same precision fit for about 55% less. No appointment, measured from two photos, and your earplugs ship within a few business days.
Why the right size changes everything
Comfort that lasts
The right size sits comfortably for hours. No pressure, no slipping, even when you sleep on your side.
Protection that actually works
Earplugs only reach their certified noise-reduction rating when they seal properly, and the correct size is what makes that seal.
Kinder to the planet
When the size is right first time, fewer earplugs come back. That means less shipping, less packaging and less waste. It’s why our return rate sits at around 3%.
The technology behind it
- AR mapping: reads the individual contours of your ear from your two photos. No specialist hardware, just your phone.
- AI sizing: compares your measurements against our size library and recommends the fit that’s right for you.
- Your data stays yours: the photos are used only to work out your size. They aren’t stored or shared, and everything follows our Privacy Policy.
- Fit guide included: simple insertion tips come as standard, so they’re comfortable from the first minute.
Your questions, answered
Earplugs only work when they fit. Too big and they hurt. Too small and they fall out and protect nothing. Most people pick a size at random, find it doesn’t fit, and give up. AR KI TECH sorts that out. Photograph your left and right ear, upload the two photos, and we tell you which size is right for you.
No app, no account, no subscription. Open the page, upload two photos, get your size. Your browser is all you need.
A few minutes. Most of that is taking the two photos. Uploading and getting your result take seconds.
It rarely happens, but ears can be tricky. If the recommended size is off, we’ll arrange an exchange with no hassle and no lengthy support chat. We stand behind the system, and behind you.
They’re used only to work out your size. Not stored, not shared, and never used to train AI. Your ear stays your ear, and it’s protected under our Privacy Policy.
Our return rate is around 3%, well below the industry average. That’s AR KI TECH doing its job. Over a million people have used BOLLSEN, and most never need to reorder because the first size is already right.
