How to read this table

Rows with a soft yellow background differ between the models shown. Battery figures are manufacturer claims with ANC on (playback volume and Immersive/Spatial modes can reduce runtime). Codec support depends on your phone’s Bluetooth stack — LDAC and aptX Adaptive need compatible Android devices; Apple devices typically use AAC.
