This is a so-called "sleep-friendly" earphone. It's a Bluetooth earphone made by Anker, and the body is very thin. Even when using a hard pillow, the earphones don't touch the pillow, so your ears won't hurt. It's already discontinued by the manufacturer, and only available while supplies last at retailers. Online retail price: 12,990 yen (as of December 22, 2024, on Kakaku.com) I've used it for about a year, but only about 20 times. If you want a reliable Anker sleep-friendly earphone instead of a cheap Chinese brand, this is for you.
