Supported codecs

A codec is an “audio coding algorithm” used when transmitting sound wirelessly via a Bluetooth connection.

The headset supports the following codecs.

When connected in Classic Audio via an A2DP connection (for music playback): SBC, AAC

When connected in LE Audio: LC3

  • SBC

    This is an abbreviation for Subband Codec.

    SBC is the standard audio coding technology used in Bluetooth devices.

    All Bluetooth devices which use Classic Audio support SBC.

  • AAC

    This is an abbreviation for Advanced Audio Coding.

    AAC is mainly used in Apple products such as iPhone that can provide a higher sound quality than that of SBC.

  • LC3

    This is an abbreviation for Low Complexity Communication Codec.

    LC3 is a codec for LE Audio and achieves low latency transmission.

When music in either the SBC or AAC codec is transmitted from a device connected in Classic Audio, the headset switches to that codec automatically and plays back the music in the same codec.

If the connected device supports a codec of higher sound quality than SBC, you may need to set the device beforehand to enjoy music with the desired codec from the supported codecs.

Refer to the operating instructions supplied with the device regarding setting the codec.
