Bluetooth headphones and earbuds use SBC or aptX codecs because they are widely supported by Bluetooth devices and provide a high-quality audio streaming experience.
SBC (Subband Coding) is a mandatory codec for all Bluetooth devices and is designed to provide a basic level of audio quality. While SBC may not provide the highest quality audio streaming experience, it is widely supported by Bluetooth devices and is capable of providing a reliable audio streaming experience.
aptX is a high-quality Bluetooth audio codec that is designed to provide low-latency and minimal audio dropouts during audio streaming. This codec is particularly well-suited for long distance audio streaming, as it is optimized for high-quality audio transmission over Bluetooth. To use the aptX codec for Bluetooth audio streaming, both the transmitting and receiving devices must support the codec. In addition, the devices must be paired and connected using the aptX codec.
It should be noted that there are other Bluetooth audio codecs available, including LDAC and AAC. Each of these codecs has its own strengths and weaknesses, and the best codec for a particular use case will depend on a number of factors, including the Bluetooth version of the devices, the available bandwidth, and the desired audio quality.
Overall, SBC and aptX are popular choices for Bluetooth headphones and earbuds due to their widespread support and high-quality audio streaming capabilities.
