This new S7/S7 Pro platform (not to be confused with aptX Lossless) allows headphones and speakers to connect to phones using “micro-power” wifi for up to 192kHz lossless music quality in the S7 Pro. Some other features includes better adaptive ANC and more powerful DSP.
I do think there’s still a major difference between Bluetooth and lossless on high-quality speakers or headphones, and once this is figured out then it will obsolete the need for wired connections.
