The Sennheiser MX 680 are in-ear headphones designed specifically for use in extreme conditions or while working out. They are constructed of highly flexible, shock-resistant materials while the cord is covered in durable reinforced Dupont Kevlar. Additionally, the MX 680s sports an acoustically open design, high-output drivers and a detachable extension cable.
The MX 680s' shock-resistant construction and Kevlar cord allows them to be used in more extreme conditions without risking damage; the MX 680s can be used in -10 degree Celsius while maintaining their flexibility. Their acoustically open design ensures that the MX 680s allow a certain amount of outside noise in, allowing runners and joggers to be safer in urban areas. Meanwhile, the MX 680s' detachable extension cable allows users to better adjust cable length for added comfort while offering optional volume control.
