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 in your cart when you order, send two photos from your order confirmation page, and we ship the size that fits you.
No marketing fluff. Just the stuff you actually want to know, from our hearing protection specialist and resident tech geek, 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, realize it doesn’t fit, and give up altogether.
AR KI TECH fixes exactly that. Add your earplugs to the cart, switch on the AI Online Ear Measurement there, and place your order. Right after checkout, your order confirmation page shows how to take the photos and a form to send them. We confirm by email once they’ve arrived. Our system works out whether small or medium fits you, and that’s the size we send. Sounds fancy, but it’s genuinely simple.
In your cart. Pick your earplugs (Life+, Music SoundPRO, Moto+, WorkPRO or Watersafe+) and add them to the cart. Then switch on the AI Online Ear Measurement (AR KI TECH) in the cart and check out as usual. Right after checkout, your order confirmation page shows how to take the photos and a form to send them. We confirm by email once they’ve arrived. 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 on your order confirmation page takes a few seconds. We confirm by email once they’ve arrived, then do the rest and 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, your earplugs block out noise the way they were designed to.
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 show. For anything more specialized, take a look at our FAQs.
