2. If your headphone stand should have become rocky this is how you can straighten it
again.
You can straighten the headphone stand by taking its corners in both your hands and
strongly pushing the corners that are slightly up towards each other and hold then
this position for about 10 seconds. Let the unit rest for some time and then repeat
the procedure for as many times as necessary.
