Exclusive design commissioned and co-designed by Massdrop, taking the far more expensive Grace m920 and repackaging it in a smaller/more affordable device
Final VerdictWhen the device is muted, the display uses a PWM scheme to make the screen pulse. The noise you are hearing is a by-product of this. This noise is usually only heard on very sensitive headphones like IEMs. When the unit is un-muted, there should be no noise caused by the display. This is normal behavior and should not be cause for concern. Please let me know if you have any questions!
