Hot on the heels of its new $1,200 Walkman, Sony has unveiled a new product for audiophiles with money to burn: A $160 memory card specially designed for song files.

The 64 gigabyte SR-64HXA micro SDXC can play back music with less electrical noise than the standard memory card, Sony told the Wall Street Journal. It also comes at roughly five times the price of its slightly noisier rivals.

Even Sony doesn’t know if people will buy a more expensive but quieter memory card. “We aren’t that sure about the product’s potential demand,” a Sony spokesperson admitted the Journal.

The company will get a better sense of the memory card’s potential when it goes on sale in Japan next month.
