Nuraphone is one of the successful kickstarter campaigns.
These boast of being the first set of headphones that automatically, in a minute, reads your ear and calibrates the sound based on how you hear sound. Like we repeatedly say in Head-fi - Hearing is subjective, and highly personal- these headphones address exactly this and projects the sound based on the subject's ear profile.
These really work, and as promised, you will hear every note, and feel every beat. No kidding!
