18. An apparatus, comprising:
a memory configured to store a computer program code; and
one or more processors coupled to the memory, wherein the computer program code causes the one or more processors to be configured to:
send audio data to a first earbud of a true wireless stereo (TWS) headset through a first connected isochronous stream (CIS) in a first connected isochronous group (CIG) from a first anchor point of the first CIS; and
send the audio data to a second earbud of the TWS headset through a second CIS in the first CIG from a second anchor point of the second CIS,
wherein the first CIS and the second CIS share a CIG presentation point of the first CIG, and
wherein the CIG presentation point is a time point at which the first earbud and the second earbud play the audio data.
