Hefio Demo Day



Next Friday the 13th (May) from 10 to 18 you are welcome to come to the Urban Mill (3rd floor)* and have a listening experience by trying out our Hefio One. You can bring your own headphones for comparison.

Hefio One is the first self-calibrating headphone on the market. They measure the individual frequency response at the eardrum and are actively calibrated to produce a desired frequency response. They are ideal for professionals in audio and meet a market need for control over reproduced sound, maximum fidelity, and individualization.
