Vienna startup ohrheld gets €150K to build custom 3D-printed earplugs
What's the deal? Ohrheld, a Vienna-based startup making custom-fit sleep earplugs via smartphone scanning and 3D printing, has secured around €150,000 in funding from Austria's Research Promotion Agency (FFG). The grant will help the company develop a fully digital ordering process — from phone scan to finished product — eliminating the need for an in-person visit to a hearing specialist.
The earplugs are designed for sleepers who struggle with pressure, discomfort, or plugs that fall out during the night. Ohrheld plans to sell them for €49.99, a steep discount from the roughly €150 that custom-moulded earplugs typically cost at a hearing specialist.
Why now? The startup validated demand early. A LinkedIn post drew about 100 people willing to pay for a prototype within a month. Three product versions have already shipped to pilot customers, and the team has tested around 20 iterations since building its first prototype on a second-hand 3D printer.
Co-founder Léon Aricioglu started the company after finding the traditional earplug fitting process cumbersome and opaque. The FFG grant now gives the team resources to refine its core tech before a broader launch.
What could go wrong? Smartphone-based ear scanning is unproven at scale. Achieving a reliable, comfortable fit without professional oversight is a significant technical challenge — and one where even small errors could undermine the product's main selling point.
Pricing at €49.99 also leaves thin margins if production costs don't fall as planned. And competing against cheap disposable earplugs on one side, and established hearing-care brands on the other, means ohrheld will need to nail both quality and distribution.
The signal: Ohrheld sits at the intersection of two broader trends: direct-to-consumer health products and accessible 3D printing. As scanning technology on smartphones improves, more startups are trying to digitise processes that once required specialist appointments — from dental aligners to orthopaedic insoles.
The company plans to expand beyond sleep earplugs into music, events, focused work, and travel. If its scan-to-print pipeline works, it could become a platform for various custom-fit ear products, all manufactured in Austria. A waitlist is already open for the official launch.
