SOUND TOOLS FOR CREATIVE MINDS Our obsession is the interaction between sound and creativity. Our passion is building beautifully designed, technically sophisticated sound tools for creative minds. Our MH40 Over Ear Headphones are designed to be the modern thinking cap, a tool to help you focus and tune into your work while tuning out the world around you.
DESIGNED FOR DECADES OF USE Our headphones are designed to be an essential part of your everyday creative toolkit that can stand up to decades of use. They are built with the creative workspace in mind, intended as a permanent fixture on your desk, workbench, or table. Our headphones are constructed of a forged aluminum body, and utilize stainless steel components in all high strain areas. Areas subject to heavy wear, such as cables and ear pads, are built to last and be easily replaced as needed.
APPOINTED WITH THE FINEST MATERIALS Our headbands are constructed with a premium grain cowhide on the exterior surface and lined with a soft lambskin. The ear pads are memory foam, wrapped in lambskin, providing superior comfort and breathability. Our heavy-duty woven cables utilize oxygen-free copper to ensure pure sound and reduced noise. All headphones include a genuine leather box to store your extra cables and accessories, as well as a canvas carrying case with a soft interior lining.
A RICH, WARM SOUND We sought a rich, warm sound signature from our custom 45mm neodymium drivers. An expansive soundscape that perfectly captures the exceptional detail that well recorded music has to offer. Our tuning is designed to accommodate a diversity of tastes and musical genres.

MAINTENANCE AND TROUBLESHOOTING Clean ear pads and headphones with soft, slightly damp cloth. Do not soak, submerge or allow moisture to enter near the drivers or cable jacks. Ear pads and cables can be purchased if they are worn out at: www.masterdynamic.com No Sound: • Check to make sure all plugs are fitted completely into their jacks, both in the headphones and at the audio source. Do not drop, sit on, or allow the headphones to be exposed to water, moisture, or temperature extremes.
HEARING HEALTH AND FITNESS Our ability to hear is amazing. Treat your ears like the precious tools they are, and they will continue to provide you with exceptional data, as well as a lifetime of incredible sonic experiences. In general, do not listen “too loud or for too long,” and be attentive to your own ears. Ringing, discomfort, or sensitivity to high frequencies and treble may be a signal from your ears that you are pushing them to their limits and causing damage.
PREVENTION OF NIHL (NOISE INDUCED HEARING LOSS) NIHL is a preventable condition caused by both one-time and extended exposure to excessive decibel (dB) levels. This harm to sensitive inner ear structures is irreversible and people of all ages can be affected. Damage can happen in a single event or gradually over time. One-time exposure to sounds louder than 110 decibels and extended exposure to sounds over 85 decibels can cause harm.
