Who it fits
Good fit for
This headphone suits listeners who need isolation in noisy environments. The closed-back design blocks external sound effectively. You will appreciate it if you work in a studio or a busy office. The planar driver offers efficient performance in this sealed enclosure. The large earpads and padded headband help during long mixing sessions. If you prefer not to disturb others or be disturbed, this setup fits your needs. It is built for focused listening rather than casual outdoor use.
Who should skip it
You should look elsewhere if you need active noise cancellation. This model relies on passive audio isolation only. It lacks electronic noise reduction technology. You may also skip this if you prefer lightweight gear. At 2.53 pounds, it is heavier than many standard headphones. The closed-back design means you cannot hear your surroundings. This is not ideal for commuting or running. If you need transparency mode or Bluetooth connectivity, this wired studio option is not for you.
Verdict: The Monolith M565C delivers strong isolation and efficient planar performance for studio work. It is a solid choice for focused listening in noisy spaces.
Key specs explained for M565C
Driver Size: 66 mm
This measurement indicates the diameter of the planar magnetic driver inside the ear cups. A 66mm size is larger than the standard 40mm or 50mm drivers found in many consumer headphones. Larger drivers can move more air, which often results in deeper bass response and a wider soundstage. You should look for this spec if you want detailed audio reproduction. It suggests the headphones can handle complex musical passages with clarity.
Form Factor: Over-ear
This design means the ear cups fully enclose your ears rather than resting on them. Over-ear headphones typically provide better passive noise isolation and greater comfort for long sessions. The padding around the ear cups creates a seal that keeps outside noise out. This is ideal for studio work or focused listening. You will notice less fatigue compared to on-ear models because pressure is distributed around the ear.
Noise Cancellation: Audio isolation
The M565C relies on its closed-back design to block external sound rather than using electronic noise cancellation. This physical seal prevents outside noise from entering and your music from leaking out. You benefit from a private listening experience in noisy environments. Unlike active models, there are no batteries or microphones involved. This makes the headphones reliable for continuous use without needing to charge power sources.
Driver Type: Planar Magnetic
Planar magnetic drivers use a thin diaphragm with conductive traces suspended in a magnetic field. This technology often delivers faster transient response and lower distortion than dynamic drivers. You get precise audio details and consistent sound across frequencies. The symmetrical magnet structure mentioned in the features improves efficiency. This spec is key for audiophiles seeking high-fidelity performance in a closed-back enclosure for studio monitoring.
Design and Build Details
The Monoprice Monolith M565C features a closed-back acoustic design with an over-ear form factor. According to the listing, the earpads are made of faux leather. These large pads, combined with a padded headband, are engineered for extended listening sessions. This material choice suggests a focus on comfort during long studio or home use, rather than breathability for intense physical activity.
The build dimensions are 10.2 inches in width, 9.84 inches in length, and 3.94 inches in height. The unit weighs 2.53 pounds. This mass indicates a substantial build, likely due to the internal components required for the 66mm planar magnetic driver. The weight may provide a secure fit for some users, but it could cause fatigue for others during very long periods of wear.
The color is black, offering a neutral finish suitable for professional environments. The closed-back construction is described as providing audio isolation. This means outside noise stays out and music stays in. This layout makes the headphones suitable for less silent environments where you need to focus on your audio without distraction. The design prioritizes isolation and comfort over portability or lightweight convenience.
Setup And Everyday Use Guide

Before You Buy M565C
The Monoprice Monolith M565C is a studio-grade headphone. You must check your audio source compatibility. This device does not mention Bluetooth or wireless features. You will need a wired connection. Planar magnetic drivers often require more power than standard headphones. You should verify that your amplifier or DAC can drive the 66mm driver effectively. Without sufficient power, the sound may lack clarity. The closed-back design provides audio isolation. You should use these in quiet environments to maximize benefit. Upkeep is simple. The faux leather earpads and padded headband require occasional cleaning. Wipe them with a dry cloth. Do not use harsh chemicals. The 2.53-pound weight is substantial.
