What is a Bluetooth codec?
A Bluetooth codec is a technology that compresses and decompresses audio data for transmission over Bluetooth connections. It determines how audio is encoded before being sent to a device and how it’s decoded when received. Different codecs can affect sound quality, latency, and overall listening experience. Common codecs include SBC, AAC, aptX, and LDAC.
Selecting the right Bluetooth codec can significantly enhance your audio experience. For instance, if you’re streaming high-quality music, choosing a codec like aptX or LDAC—if supported by both your iPhone and Bluetooth device—will typically yield better sound than the standard SBC codec, which is lower in quality.
How can I change the Bluetooth codec on my iPhone?
To change the Bluetooth codec on your iPhone, you’ll generally need to access your device’s settings and establish a connection with the Bluetooth device you wish to use. Once connected, go to “Settings,” then “Bluetooth.” From there, find the device in the list and click the “i” icon next to it.
