“I`ve had these for about 2 months now so I think I have a pretty good idea of what they are all about. Before I started using them, I let them burn in for about 100 hours.

They introduced FX650 to replace the FX500 and FX750 to replace the FX700, in addition to announcing the new flagship, FX850. Thanks to user James444, I was able to hear all 3 IEMs of this new...” --Inks
