Sony has added to the colour options in which it already sold the WH-1000XM4. From the middle of this month, the company will begin selling its latest over-ear headphones in Midnight Blue, which also has gold accents. The Midnight Blue model will not be a limited edition and is US$100 cheaper than the limited Silent White version.
