What's the difference between Bluetooth and non-Bluetooth audio?

1. The current of the player can directly enter the speaker-driven diaphragm through wires. Stable signal, wider bandwidth, more dynamic, no delay.

Bluetooth converts electrical signals into radio signals, and then restores them to electrical signals. Because wireless signals themselves cannot transmit high-quality electrical signals, it sounds even more embarrassing. If the pursuit of sound quality, it is better to take a line.
