Here's the pitch: Everyone has a different ability to hear different musical frequencies. So there are whole sections of music on your favourite song that you just cannot hear well.

Melbourne inventors Dr Luke Campbell, 30, and Kyle Slater, 29, claim to have invented a pair of headphones that can detect your personal hearing signature and adapt the sound of the music you're playing so you hear every element of the song.

"We think about it in terms of filling in your musical black spots," says Slater.

The pair have raised more than $700,000 in only a few weeks on Kickstarter, and already have prototypes and manufacturing partners locked in. They are calling it the Nura.
