The Sony MDR-XB650BT are fairly large on-ear headphones. One of the hallmarks of Sonys XB range is their large pads. Although still present in the MDR-XB650BT, in recent years Sony has toned them down a little.
Like many of the companys recent headphones, the Sony MDR-XB650BT look sharp. Black for the plastic bits, naked silver where theres metal; its a classic Sony look.
