Page 15: Rear Panel Connections/Controls
Coaxial S/PDIF input HEADBAND ADJUSTMENT To get the best from your M1 headphones, it is important to ensure that they are correctly adjusted to fit your head, and that they are properly positioned on your head. The headband can be adjusted by means of an inner band that can be lengthened/shortened as needed. -
Page 16: Positioning The Headphones
POSITIONING THE HEADPHONES The headphones should be positioned on your head such that the headband is vertical. When you have the correct adjustment and orientation, you will have a good seal of the ear-cup pad around your ear which is essential for correct bass response. You can check whether you have a good seal by carefully pushing on the ear-cup. -
Page 17: Detaching The Headphone Cable
DETACHING THE HEADPHONE CABLE Should you need to detach the cable for any reason, grasp the barrel of the cable and carefully pull backwards until the cable disconnects. You can then release the barrel and it will return to its usual position. -

Page 27: Care And Maintenance
CARE AND MAINTENANCE POWER DOWN Due to the fact that the M1 amplifier/DAC generates high-voltages and also runs warm in use (this is perfectly normal for a Class-A amplifier), it should be powered down when not in use for extended periods or left unattended. -
Page 28: Replacing The Headband Pad
REPLACING THE HEADBAND PAD The headband pad is held in place by the small plastic tabs marked L and R on each side of the headband. To remove one of the tabs, use your thumb to carefully push the sidewall outwards (do this at the thicker part as indicated). -
