Oliver Schusser, Apple’s Vice President in command of operating Apple Music, lately gave an interview to Billboard journal wherein he mentioned a variety of matters, together with the usually thorny subject of lossless audio.
Following that interview, a number of media retailers reported Schusser as having stated that “most individuals can’t inform the distinction” when listening to lossless or high-res audio. The truth is, what he actually stated was – “lossless really doesn’t work over Bluetooth. When you’ve got a wi-fi connection, lossless doesn’t really work”. So Schusser was actually stating the constraints of utilizing Bluetooth for wi-fi headphones, somewhat than saying that lossless audio doesn’t matter in any respect (or, as urged by some retailers, that it solely issues to pretentious audiophiles who prefer to fake that they’ll hear the distinction).
It’s true that Bluetooth does require audio recordsdata to be closely compressed for wi-fi transmission, and that compression can have an effect on the audio high quality even when utilizing actually costly Bluetooth headphones comparable to Apple’s personal AirPods Max.
