The He500 are fantastic sounding headphones, but unfortunately have bad ergonomics due to their weight and look dated by todays standard. This pair of He-500’s has been vastly improved visually and audibly with the following:

• Headband swap to the new Hybrid version.
• Earcup swap to He5Se cups.
• Felt Fussor mode to minimize treble reflections,
• Sorbothane dampening of earcups
• 3.5mm terminated instead of the finicky SMA connectors.
• Replaced the restrictive grills with wider mesh and sheen fabric to open up soundstage.
• Focus Pad A and Jergpad earpad improvements.
• custom 3.5mm braided cable.
