AR KI TECH – Perfect Earplug Fit with AI + AR
We were the first hearing-protection brand to combine Augmented Reality (AR) and Artificial Intelligence (AI) to determine your ideal earplug size from simple ear photos. With AR KI TECH, customers start with the right fit and comfort—helping us keep returns around 3% and making BOLLSEN one of the most eco-friendly choices in hearing protection.
What is AR KI TECH?
AR stands for Augmented Reality, KI (German: Künstliche Intelligenz)
stands for Artificial Intelligence. AR maps your ear geometry from photos; AI analyzes measurements and recommends
the BOLLSEN size that best matches your anatomy—so your earplugs feel comfortable and seal reliably from day one.
How it works
- Take two photos – one of each ear, in good light, straight on.
- Upload securely – use our uploader to submit your images in seconds.
- AI + AR sizing – our system maps your ear canal region and suggests the ideal size.
- Order with confidence – choose the recommended size and enjoy a perfect start.
Why it matters
Comfort from day one
Right size = easier insertion, secure seal, all-night comfort (great for side sleepers).
Better protection
A proper seal helps your earplugs perform closer to their certified attenuation potential.
Lower returns ≈ 3%
Fewer size swaps mean less transport and packaging—better for the planet, better for you.
