There are two reasons why the sound quality of Bluetooth headsets has been criticized:
The sound quality of Bluetooth headsets has been criticized for two main reasons: When Bluetooth transmits audio data, the audio is lossy compressed, which loses the sound quality. Digital-to-analog conversion and amplification are all done inside the Bluetooth headset. It’s hard to do both at the same time, so for portability and price, you further sacrifice sound quality.
The second point is the main reason. After understanding the principle of bluetooth headset, we know that to make the bluetooth headset work normally, it is necessary to install a battery, a bluetooth module, a digital-to-analog conversion circuit, an amplifier circuit, a headset unit, etc. in the headset shell. A series of components, which is a very test of the manufacturer’s product design capabilities and comprehensive technical strength. However, this step is only to meet the needs of “voice”. If you want a good sound, you also need to tune. In this link, you need to verify the specific performance of the earphone sound under different materials, different diaphragms and different wires. In short, it is a relatively complicated process and is also the main R&D cost of the manufacturer.
