Too big, too small, always falling out? We know the feeling. That’s why we built AR KI TECH. It uses Augmented Reality and Artificial Intelligence to find your earplug size from two photos of your ears. Add it to your order on the product page, send us two photos afterwards, and we ship the size that fits you.
No marketing fluff. Just the stuff you actually want to know by our Hearing Protection specialist & Tech Freak Tom.
Simply put: earplugs only work when they fit properly. Too big = uncomfortable and painful. Too small = falls out, protects nothing. Most people just pick a random size, realise it doesn’t fit, and give up altogether.
AR KI TECH fixes exactly that. Add it to your earplugs on the product page and place your order. Your order confirmation page then shows you how to take two photos of your ears, left and right, and a form to send them. Our system works out whether small or medium fits you, and that’s the size we send. Sounds fancy, but it’s genuinely simple.
On the product page. Pick your earplugs (Life+, Music SoundPRO, Moto+, WorkPRO or Watersafe+), add the AI Ear Measurement (AR KI TECH) in the box under the add-to-cart button, and check out as usual. Right after checkout, your order confirmation page has the photo instructions and the form. No app, no account, no subscription. Your phone camera is all you need.
About 2 minutes on your side. Taking the photos takes a minute and sending them through the form a few seconds. We confirm by email once they’ve arrived, then ship your size.
It rarely happens, but ears can be tricky. If the size we sent isn’t quite right, write to us and we’ll sort it out. Your order is also covered by our 40-day money-back guarantee.
We use them only to choose your size. We don’t store them and we never share them. That’s a privacy measure, in line with our Privacy Policy.
Fair question. AR KI TECH picks your size from photos of your own ears, so most people get the right size the first time and never need to swap. Over one million people already wear BOLLSEN earplugs.
Every ear is different – and that’s exactly why one-size-fits-all simply doesn’t work. AR (Augmented Reality) measures your ear from your photos. AI (Artificial Intelligence) compares those measurements with our sizes and picks the one that fits you, small or medium. The result: earplugs that sit right, seal well and feel comfortable from the start.
No pressure, no slipping. The right size sits comfortably all night long – even on your side. Side sleepers, we see you.
Hearing protection only works when it seals properly. With the right size, you actually reach the certified noise reduction values – exactly as they’re meant to be.
The size is right from the start, so fewer pairs get sent back. That means less shipping, less packaging and less waste.
AR KI TECH works with our conical earplugs made from soft, hypoallergenic silicone: Life+, Music SoundPRO, Moto+, WorkPRO and Watersafe+, whether you wear them for sleep, focused work, travel or your next gig. For specialist applications, have a look at our FAQs.
Choose your earplugs, add AR KI TECH, send two photos. We ship the size that fits.
