Hifiman Headband Slider + Caps (HE-500, HE-400...)

thingiverse

This is a slider raplacement for the original used on older HE models. The fix is easy, the part is easy to print and works like a charm. I made this to fix my broken HE-500s as I did not wish to spend 60+ USD on new headand which does not even fit without tinkering and drilling. I include both sides of the part. The repair wil take You about 10 mins. Fits left as well as the right side. Here's how to: Gently remove the cover it is glued with melting glue. Use a hairdrayer or hotgun if You feel the need to. Remove old glue to acces the screws. Do not lose them :) Save or replace the O-rings you will find inside. I reccomend replacing them, the rubber after years of use may come loose soon anyway. You can buy the O-rings in local hardware store, they are really cheap. If You broke the inner part is slightly harder to fix. You have to cut the leather from the other side of the headband. Locate the screw by feel. Try to make the cut as small as possible as it will remain there, just big enough to be able to unscrew the screw. Replace with printed parts, do not forget the O-rings re-asemmbly. Check the heaphones. Cover the cut with tape or use glue or leave as is. It's Your choice. Glue the cap back using hot glue. That's it PS: use stronger materials, dense infill, I used Polymax PLA, the headphones work for over a Year as good as new.
