Regardless of whether it is a Bluetooth or a smart speaker, from the perspective of the speaker, in fact, everyone really cares about the sound quality after all. The theoretical transmission speed of the current mainstream Bluetooth 3.0 and Bluetooth 4.0 is 24Mbps, although it seems that it can meet the high-quality lossless transmission , But the actual speed is not up to the theoretical value and the audio is compressed, and the built-in DAC is used for low signal-to-noise ratio and high distortion decoding, which is intolerable for many audio enthusiasts.
