The fold flat feature of the PXC 550 enables you to have it lying flat above your chest for maximum comfort when you are not listening your music.
A quick twist of the earcups, and I was surprised just how compact the PXC 550 is. Most over-ear headphones will look massive and definitely out of place when you are out and about, but the use of black materials and muted metallic highlights makes the PXC 550 very discreet.
Ample cushioning around the earcups covered in soft leather. The earcups themselves are quite small; perfect for me, but for those with bigger ears might cause a little discomfort.
Again, there is lots of cushioning and use of soft leather on the headband.
