Sony revealed a microSD card that Delivers Premium Sound

Sony invented a new line of microSD cards that can produce better sound if they are made from the right materials and tuned just right to minimize electric noise coming from the card while it's working.

It theory a poorly designed component could interfere with the electric system of a phone or MP3 player and mess up the accuracy of its amps. Though in reality the label is an audiophile placebo that will cost around $155 when it comes out in Japan on March,5th.

Either way, unless you paid twice as much for your headphones than you would for this card and you listen exclusively to FLAC, you don't need the Premium Sound microSD card. And even if you do, you probably still don't need one.
