I love mine and use it almost all the time. Its a Surfans f20 with rockbox native installed. Makes it feel like I’m using my old ipod lol
I’ve always found it interesting that I cannot stand Nine Inch Nails on my BT headphones, but I really enjoy The Downward Spiral on my father’s good studio headphones.
Oh NIN… One of my first albums was Further Down the Spiral. Wow. What a discovery. Mind blown.
Trent Reznor is a peculiar one though. He is opposed to digital music and thinks music should be enjoyed on a CD or vinyl. It wouldn’t surprise me that his work is mastered in a way that favours certain formats.
