Which is better, Bluetooth audio or wired speaker?

1、 Different sound quality:

Due to the cost of more related chips in Bluetooth audio, the bandwidth of Bluetooth transmission technology is insufficient to transmit lossless audio signals, and Bluetooth decoding will also have an impact. In addition, there will be packet loss in wireless transmission. Pay attention to sound quality performance. It is recommended to choose a cable audio product in the same price range.

Compared with the audio quality of a cable audio system at the same price, the cost of a Bluetooth audio system is higher due to the need to add a Bluetooth chip and a decoding chip. In addition, the audio signal will be compressed during transmission due to the Bluetooth transmission technology, which will affect the audio quality to a certain extent.

2. Different transmission technologies:

The transmission rate of Bluetooth 4.2 is 1Mbps. Compared with Bluetooth 4.2, the theoretical transmission rate of Bluetooth 5 is doubled, from 1Mbps to 2Mbps. This transmission rate is equivalent to the general MP3 resolution, which is sufficient. If the transmission is lossless and the current HiRes audio is obviously a bit difficult, data compression is required to achieve effective transmission.

3. Different environments:

Due to wireless transmission, due to the complex electromagnetic environment, packet loss will occur during transmission, which will also affect the sound quality to varying degrees.
