This $155, audiophile-friendly microSD card from Sony is... quieter than competitors'?82
Dubbed SR-64HXA, Sony claims that its internal measurements clearly show that competing Class 10 microSDXC cards emit more electrical noise when reading a file off the memory. That's why the company has slapped a golden "for Premium Sound" gag line on the chip, and, of course, a ¥18,500 (~$155) price tag.
While Sony probably thinks that the SR-64HXA will go hand-in-hand perfectly with that $1,200 Walkman it announced at CES 2015, we can't help but feel dumbfounded at the thought of buying into 'quieter' SD cards. Quite frankly, even a Sony spokeperson, cited by The Wall Street Journal, seems unsure of what to make of this:
When your own employees are as unconvinced in your product's chances, you've got yourself a serious problem, Sony. We'll know for sure come March 5th, when the first-of-its-kind microSD card will be available for purchase in Japan.
