Apparatus for reproducing sound and headphone comprising same

A headphone for reproducing sound comprising:

• an isolation switch configured to receive a first audio signal associated to a first reference level and selectively output or isolate the first audio signal;
• a wireless communication component configured to wirelessly receive a wireless input signal and to generate and output a second audio signal associated to a second reference level based on the wireless input signal, wherein the second reference level is different from the first reference level;
• and
• an audible component connected to the isolation switch and to the wireless communication component, respectively, and the audible component is configured to receive, based on determining a state of the isolation switch and a mode of the wireless communication component, one of the first audio signal from the isolation switch or the second audio signal from the wireless communication component and to emit a sound signal based on the received audio signal so that the second audio signal and the first audio signal do not interfere with each other.
