Verdict

The Monoprice Monolith M600 is an open-back headphone featuring a 50mm beryllium dynamic driver designed to deliver balanced sound with a focus on natural, forward mid-range frequencies. Technically, it operates with an impedance of 64 ohms, a sensitivity of 98 dB, and a frequency response ranging from 20 Hz to 20 kHz. Key characteristics include a real wood earcup construction, a durable metal-structured headband, and a 2-meter detachable cable with dual 2.5mm connectors. Main pros are its lightweight design, spacious sound imaging, and the inclusion of both leather and velour ear pads plus a hard shell carrying case. However, notable cons include a small earcup opening that may press against larger ears, treble that some find lacking in crisp detail or impact, and a headband sizing that can be too large for those with smaller heads.
