My FXC51 died yesterday.
The right driver simply fizzled out while I was listening to them, I am outside of the 1 month amazon return policy and I will not be buying a second pair of these and waiting another 4 weeks for delivery.
I had some intimate amazing moments with them with goa trance and playing around with an equalizer, but with driver quality like that I will go back to recommending the Jays a-Jays Two and Audio Technica ANC23 for IEM's priced under $50.
Soon the Sony XBA-1 is coming and will hopefully kill all IEM's priced under $100.
My left driver is dead. I treated them with atmost care. But I don't really care anymore, I've got an EX600 now.
I'm also interested in the XBA-1.
