However, the audio quality can be a bit inconsistent at times. It provides fairly good audio quality without requiring a lot of processing power to encode or decode. It is capable of bit rates up to 328 kbps with a sampling rate of 44.1kHz. SBC - Sub-band Coding - The mandatory and default codec for all stereo Bluetooth headphones with the Advanced Audio Distribution Profile (A2DP). The 3 main codecs that most listeners are familiar with are SBC, AAC, and aptX: However, since this codec has a relatively high latency and may be a bit lossy, companies have developed their own encoding algorithms, like Samsung's UHQaudio and Sony's LDAC. The efficiency of the codec will determine the quality and rate at which the audio data is sent. SBC is the default sub-band coding for most Bluetooth devices. Codecs are encoding and decoding algorithms that compress audio into manageable data packets for faster or wireless transmission.
