Headphone Testing

Headphones are a pair of conversion units that accept electrical signals from a media player or receiver and convert them into audible sound waves using speakers close to the ears. Headphones are an indispensable electronic product in our daily lives. We can use them to listen to music, watch videos, chat, etc. From the invention to the present, headphones have continued to develop with the advancement of people's technology. In order to ensure the performance and quality of headphones, the testing of headphones is crucial.
