    摘要： A pair of headphones may include first and second ear cups that each contain one or more speakers. The speakers may emit audio through a sound-permeable warp knit spacer fabric that is coupled to each ear cup. The warp knit spacer fabric may include inner and outer fabric layers joined by a spacer layer. The outer fabric layer may have first and second regions with different fabric densities. The first region with the greater fabric density may be used to form a label such as an R-shape or L-shape to indicate which ear cup should cover the user's right ear and which ear cup should cover the user's left ear. The denser first region may have diamond-shaped openings of a first size and the less dense second region may have diamond-shaped openings of a second size that is greater than the first size.
