模块化耳机 / modular headphones


when one side of the headphone still can hear,
you only need to change the broken line.It can spare the trouble to
throw away the half-broken headphones.Moreover,the users have to refer
to the same brand of headphone lines,so this is a good chance for
sellers to maintain the customer loyalty
