Marshall amplifiers have long accompanied rock guitarists all over the world. With Marshall Monitor, that same sound quality is channeled straight into listeners’ ears. The look is very masculine—a black head hook, black vinyl leather cupolas, and a gold plug—while the design is all about practicality. Once folded, the headphones reduce to the size of a fist, so they can easily be stashed just about anywhere. The Monitor has up to a 40-ohm impedance, which effectively prevents sound from leaking out, though if someone wants to listen in, there’s an extra plug that can connect with another headset.
