The K67 Tiesto Headphones from AKG are built to be comfortable, portable and durable wherever you wear them. Made for everything from home recording to listening to music, the K67 is equipped with 1.6" (40mm) drivers that are designed to deliver consistent sound reproduction. The on-ear, closed back earcups are built to reject outside sound that may otherwise interfere with your listening experience. They are equipped with the convenient 3D-Axis folding mechanism that allows for compact, flat storage. Built from XRP³ Glass-Fiber Reinforced Polymer parts to withstand wear-and-tear, the K67 is made to endure frequent use. The included 1/8" to 1/4" gold plated adapter makes the K67 a viable choice whether you are monitoring a band through a multi-track mixer, or listening to music on your MP3 player.
