I found this old gem from 2003 in my basement. It's what we like to call an "MP3 player". The brand is Neuros. The darker grey part contains a 20gb spinning hard drive that could be swapped for a larger one. It also has a built in FM transmitter. This thing was so cool in the day feature wise but looks a heck of a lot like a stud finder. Still working after almost 20 years.
