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 using Classic Audio via an A2DP connection (for music playback): SBC, AAC
When the headset is connected using LE Audio, it supports LC3.
-
SBC
This is an abbreviation for Subband Codec.
SBC is the standard audio coding technology used in BLUETOOTH devices.
All BLUETOOTH devices 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 is transmitted using one of the following codecs from a device connected via Classic Audio, the headset automatically switches to that codec and plays back the music in the same format.
SBC, AAC
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 connected device to set the codec.
When connected to LE Audio, the music playback is performed in LC3 codec. For LE Audio connections, use the “Sound Connect” app and set [Bluetooth Connection Quality] to [Low latency]. The [Priority on Sound Quality] setting at the time of purchase does not support LE Audio connection.
Refer to the operating instructions supplied with the device you are connecting to, as some settings may be necessary in advance.
