This is the "Sony WH-1000XM4 Wireless Noise Canceling Headphones." I am selling them because I no longer use them. 【Release Date & Retail Price】 The Midnight Blue version was released in December 2021, and I purchased it around that time. I only used them during the winter season. The price was around 30,000 yen. 【Condition】 There is some wear and tear, but there are no critical damages such as chips or cracks on the main body. However, there is a slight chip on the ear pads (see photos). Operation has been confirmed, and features like ANC (noise canceling) and Bluetooth connection work without any problems. Overall, they are still in good condition and perfectly usable. 【Shipping】 I will carefully package and ship them after purchase. ★Bundling with magazines, books, and pamphlets I have listed separately is welcome. Please use Mercari's bundling feature. I will offer a discount.★ Thank you for your consideration.
