Spotify Lossless requires wired connections, not Bluetooth, to actually work
Spotify's new Lossless tier delivers CD-quality, uncompressed audio, but Bluetooth connections can't transmit a true lossless signal, meaning wireless earbuds and speakers won't benefit. Listeners need wired headphones, USB-C earbuds, wired computer speakers, or Wi-Fi-based Spotify Connect devices to actually hear the improved quality, and even then, cheap audio hardware may not reveal a noticeable difference.
