Purchased last November, but I'm selling it because I haven't had the opportunity to use it.

The price comparison in the photos shows that it's cheaper than the Amazon set price of ¥25,527, as of 2026/02/01.

The original retail prices are:
HD599SE ¥20,952
4.4mm balanced cable ¥11,000
This is a great deal!

This is the lowest price for a new, unopened item, so it's first-come, first-served.
Please consider purchasing if you're interested.
