 The headset is a pair of conversion units, which receives the electrical signals sent by the media player or receiver, and converts them into audible sound waves by using speakers close to the ear. The headset can be separated from the media player, and can be connected with only one plug, so that you can listen to the audio alone without affecting others; It can also isolate the sound of the surrounding environment, which is very helpful for people who use it in noisy environments such as recording rooms, bars, trips, sports, etc.
