Well mostly because the piece that was on the end where the plug went into the device was kind of a weird rubber.
I actually called Monster themselves and found out they were fake, there's a serial number on every one apparently- not to mention there was a video on YouTube that will show you how to spot a fake- so yeah it was unfortunate.
Game, you and I are a rare breed my friend. Believe it when I tell you though, what goes around comes around man- find happiness in knowing this.
Have a great New Years brother!
