The headphone we design can remind people taking a rest after using a certain period of time through a flashing discolored line in order to protect the ears.When the volume rises above the 60% of the max,it turns yellow.And it turns from green to red after using for over an hour.On the other hand,the lines turns green while the current flow across the flat part.This help people untie theknot rapidly and happily.
