Soon we’ll be wearing headphones most of the time. But listening with traditional headphones can be very tiring! This is mainly because the sound appears to be inside our heads – an unnatural experience that we have come to accept.
During everyday listening, however, we can hear where sound is coming from, how far away things are, and what space we are in. Currently, when listening with headphones, these amazing hearing abilities are lost. That is why IDUN audio has developed dynamic spatial audio (DSA) software – to restore natural hearing when listening with headphones.
