XQ-860F3 Headphone Torsion Testing Machine 
1. Revise the application scope of the testing machine:
This machine is suitable for testing the torsion lifespan of the rotating shaft of head-mounted earphone receivers. The torsion testing method is as follows: Fix one of the left and right earphone receivers on the torsion fixture, and fix the headband on the support frame. Set the test angle and rotation speed. After conducting N tests, remove the earphone and inspect the performance of the rotating shaft.
