AKG K7xx Elastic Replacement *No Modification or Disassembly*

This is a clip in bracket to replace the worn out elastic for an AKG K7xx (701/702/712/others) series headphone. Requires no disassembly, modification, cutting, gluing, etc.

It is designed for a hair elastic (ponytail elastic) of about 4.5cm/1 ¾" diameter. You can find these elastics at a dollar store, or probably anywhere.

Elastic to bracket install:

The elastic has to be woven through the bracket to provide the required tension. 

Start by sliding the elastic into the bracket with one side on each of the Red circles ‘1’ so the bottom of the elastic is below the bottom of the bracket.

Pinch the elastic bottom together Orange ‘2’ and thread it up through the central hole, Yellow ‘3’. 

Spread the elastic back out Green ‘4’ and slide one side each over and into the Green holes ‘4’.

The elastic should now be back on the bottom of the bracket. Settle it into channel Blue ‘5’, and settle the elastic into the other channel Orange ‘2’ as well.

Bracket to headphone install:

Clip/cut the worn out elastic from the headband and ear cup. Stretching the elastic and clipping as close to the plastic as possible will give you a clean look when it retracts.

Place the bracket in between the steel headband rails, diagonally, with one side at the ear cup and one side a distance up the other rail. Slide one side of the bracket down the rail to lock it into place. Move the bracket as close to the earcup as possible.

Pop out the headband slider from the metal rails. This is easiest with the headband in the smallest adjustment position, so the slider is midway between the ear cup and fixed plastic piece on the headband rails. This gives the most flex/room in the headband to remove. The headband is spring steel and will not break, but go slow.

Weave the elastic band around the slider so the vertical part is in front, and the horizontal part is in the rear. Same as shown in the model photo.

Pop the headband slider back in.

Done!

Print Instructions:

The bracket requires a little bit of flex around the holes for a secure fit. Any flexible plastic will work for this (not PC or CF/GF filled). Be aware if you use PLA, you might get some white stress discoloration around the holes. You also might not. Either way it will work fine. Use a brim for ASA/ABS. This is printed ‘upside down’, supports don't work great on the semicircle cutout on the bottom.
