The ST750 sports a refined look, with black leather lining the headband and the edges of the earcups. The heavily cushioned black earpads and underside of the headband make for a very comfortable, lightweight fit, even over longer listening sessions. Each side incorporates the TDK logo on a brushed metallic surface. Inside the circumaural (around-the-ear) earcups, 40mm dynamic drivers bring intense audio when the power switch on the right earcup is on. The right side also houses the battery compartment—the ST750 requires two AAA batteries for powered operation.
