How Bluetooth Audio Codecs Affect Wireless Listening

Wireless headphones often advertise support for audio codecs such as SBC, AAC, aptX, or LDAC. These names can make Bluetooth audio seem more complicated than it needs to be. A codec is simply part of the process used to represent audio efficiently enough to send it over a Bluetooth connection. Codec support can influence sound quality, latency, bandwidth use, and connection stability, but the codec name alone does not determine how good a pair of headphones will sound.
