Bluetooth and codecs—Bluetooth 5.4 (Classic and LE Audio); SBC, AAC, aptX, aptX Adaptive/Lossless, LC3; A2DP, AVRCP, HFP, TMAP, PBP

aptX Lossless needs a Snapdragon Sound phone that supports it; an iPhone uses AAC. According to Sennheiser, Auracast broadcast listening only arrives through a firmware update. Multipoint lets it switch between two devices.
