Headphones are a pair of conversion units that receive electrical signals from media players or receivers, and use speakers close to the ear to convert them into audible sound waves. The earphones can be separated from the media player and can be connected using only one plug, allowing for independent listening to the audio 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, travel, sports, etc. Headphones were originally intended for use on the phone and radio, but with the prevalence of portable electronic devices, they have become more commonly used in mobile phones, walkthroughs, radios, portable gaming, and digital audio players. From the development of the entire audio industry, wireless headphones are still considered a new thing, with a relatively short development time and an upward trend. User demand is constantly increasing, and users' expectations for wireless headphones are also increasing. This is a new challenge for the industry. The key points that users are most concerned about include sound quality, battery life, wireless transmission capability, and data transmission delay. From the perspective of data, wireless transmission capability can basically meet the needs of the vast majority of users, and there is still great potential for improvement in sound quality and battery life. If we start to improve from these two aspects, we believe it will be easy to attract users' attention in the future
