The first problem: The essential difference between wired headphones and wireless headphones is that the former transmits data by data cable, and the latter transmits data through wireless technology such as Bluetooth or WIFI.
The second problem: whether the sound quality of wireless headphones will be distorted depends on the player, the source file played, the playback environment (there is no electromagnetic interference) and the quality of the headphones. The better the relevant conditions, the smaller the degree of distortion.
The third question: any electronic product will have radiation, just how much. Compared with wired headphones, the radiation of wireless headphones is relatively larger than the price, specifically refer to the People's Daily network home appliance radiation ranking.
The fourth problem: the simple comparison of cost performance of electronic products is not scientific, it is recommended that you go to the physical store to see, only the actual scene to feel, to pick the most suitable for their own is the best.
