3D Printed HiFiMan HE400se Super Grills
These inserts replace the original grills for the HiFiMan HE400se to make them sound more open and re-tune them slightly to give more sub bass.
You will need to use double sided tape or something to stick the driver wires to the black felt around the outside of the driver so the wires do not get in the way when you install it, they must not be on the magnets. We also recommend removing the fabric from the back of the original grill and placing it on top of the magnets to help prevent hairs or other debris getting inside.
