Headphones that deliver individually optimized sound.

Hefio is a spin-off venture, started in 2014 in one of the world’s reputed labs in the field of audio engineering: the Spatial Sound Lab of Aalto University, Finland. We design headphones that deliver individually optimized sound for your unique ears. Did you know that we all hear differently? Still, modern headphones don’t take individual differences into account. It is similar to wearing someone else’s glasses. This leads to a problem. The sound is always colored what results in reduced sound quality for all users. The problem is especially remarkable in VR and AR where the sound needs to be individually optimized to create a totally immersive audio experience.
