Why Does the Sound Quality of Car Bluetooth Suddenly Deteriorate?

[VonColton]

Here are the reasons why the sound quality of car Bluetooth suddenly deteriorates: 1. Unreasonable design structure: If the signal is not intermittent or has noise, then it is not a Bluetooth signal problem. Poor sound quality is mainly due to the use of inferior speakers and an unreasonable internal design structure of the cavity. 2. Low version of Bluetooth chip: Using a low version of the Bluetooth chip, during the digital signal transmission process, because the protocols are different, the output analog signal has already altered the original sound. Many domestic brands produce car Bluetooth headsets only for making and receiving calls, and they are mono, so don’t expect car Bluetooth to achieve the effect of wired headphones.
