1. The sound quality is different:
Due to the cost of more related chips in Bluetooth audio, the bandwidth of Bluetooth transmission technology is not enough to transmit audio signals with lossless sound quality. Bluetooth decoding will also have an impact. In addition, there will be packet loss in wireless transmission. Pay attention to the sound quality performance, it is recommended to choose a wired audio product in the same price range.
Compared with the sound quality of Bluetooth speakers and wired speakers at the same price, the cost will be higher due to the need to add Bluetooth chips and decoding chips to Bluetooth speakers. In addition, due to Bluetooth transmission technology, audio signals will be compressed during transmission. Will affect the sound quality.
2. Different transmission technology:
The transmission rate of Bluetooth 4.2 is 1Mbps. Compared with Bluetooth 4.2, the theoretical transmission rate of Bluetooth 5 has doubled from 1Mbps to 2Mbps. This transmission rate is equivalent to the general MP3 resolution and is sufficient. If the transmission is lossless And the current HiRes audio is obviously a bit laborious, and data compression is needed to achieve effective transmission.
3. Different environments:
Because it is wireless transmission, it is affected by the current complex electromagnetic environment, and packet loss will occur during transmission, which will also affect the sound quality to varying degrees;
