Sony WH-1000XM4 noise-canceling wireless headset released in August last year ushered in a new limited edition color, Silent White. The price and release date have not been announced yet.
The limited-edition Silent White headset (model: WH-1000XM4 WM) has more lacquer layers than the standard models and incorporates pearl colors to create a delicate texture and depth. The high-quality pure white surface feels good to the touch, gives a high-quality texture, and is also stain resistant.
Except for the color scheme, the new headset has the same basic specifications as the existing standard model headset.
