What's The Difference Between Wired Headphones And Wireless Headphones

The first problem: the essential difference between wired earphones and wireless earphones is that the former transmits data by data line, and the latter transmits data through wireless technologies such as Bluetooth or WiFi.

Second question: whether the sound quality of wireless headphones will be distorted depends on the player, the source file played, the playing environment (with or without electromagnetic interference) and the quality of headphones. The better the correlation condition, the less the distortion.

The third question: any electronic product will have radiation, just how much. Compared with wired earphones, the radiation of wireless earphones is relatively higher than the price.

Fourth question: it's not scientific to compare the cost performance of electronic products.
