In 2021, the main difference between wired and Bluetooth hifi headsets is the connection method and sound quality performance. Wired headphones are connected via a cable that transmits audio signals, providing a more stable connection and higher sound quality, but their use is limited by the cable.
The Bluetooth headset is connected through wireless Bluetooth technology, providing greater convenience and wireless freedom, but due to the process of wireless transmission and compression decoding, it may lead to loss of sound quality. Of course, the technology of Bluetooth headphones continues to improve, and some high-end Bluetooth headphones have been able to provide sound quality performance close to that of wired headphones. Therefore, in the selection, need to be based on individual needs and budget comprehensive consideration.
For the same price, the sound quality is better with wired, and the latency is almost negligible
