What’s the difference between decibels and SPLs, and how are those distinct from loudness? Also, what the heck are LUFS? Next: If EarFun’s new earphones are all that, why pay more? And can Sonos un-punch its own face?

We’re on Patreon now! Find us at https://www.patreon.com/AudioUnleashed Apologies for the sound quality this week. We had some back-end technical issues and had to rely on our compressed cloud backup audio stream for editing. With that said, the conversation is one we hope you dig. We start by digging into the reader mailbag to address comments in support of and opposed to our take on the ASR v. GR-Research kerfuffle. Next up, we dig into why Sonos felt it needed to send out an apology letter to its customers, then discuss a cool episode of Your Morning Coffee that breaks down how algorithms and pay structures affect what music we hear.
