A start-up, Nura, has developed headphones which calibrate the sound frequencies emanating from their device to match your hearing frequency.
The device takes 30 seconds⏲ to calibrate by bouncing off sounds in your ear to derive a frequency. It then stores the information unique to your ears in a profile.
It can store multiple profiles, so every time you wear it, it automatically recognises your ear frequency and brings up your profile. The effect after calibration is simply exceptional.
The headphones will retail for $399
You can donate to their Kickstarter project fund raising for a discounted $200.
