What sort of connection are you using? Wireless, I assume? Which codec? I wonder if your headphones are connected to your source device via a particularly lossy BT codec... (I know they're wireless headphones; but some wireless headphones such as previous Sonys have optional wired connections) The effect is really obvious to me in wired headphones, and my ears are pretty much trash. I struggle mightily to tell the difference between FLAC and good mp3/AAC encodes and struggle to understand people in real life sometimes. The Universal watermark is really egregious to me, particularly in the last few seconds of that "Three Doors Down" clip. It's kind of a fluttering sound in the guitars themselves, not a noise laid over the top. Not shaming anybody if they can't hear it. Like I said, my hearing is pretty bad and I have other physical disabilities.
