We are talkin' about my curated playlist, I curated a playlist that I use to test all my headphones and bluetooth speakers, and I got asked why I use this playlist and I think you personally can't really test headphones and speakers unless you know the music really well and I just believe that personally, as the thing to hear.
So you need to test new headphones and new speakers with the audio you know well and that's so you can hear how the different headphones have changed the audio as new two pairs of headphones are made the same and that's just the fact of life to be honest with you right there.
I go to in depth on this a little bit more on the DJ NATDOG PODCAST.
