A pair of my IEM's broke and I needed a replacement, these are absolutely fantastic and I want to buy another pair. Mine are still working and I bought them OCT, 17th last year. The only issue I have is that the wires stick to things pretty often and are not very smooth and supple, and they are still perfect even though I fall asleep with em in my ear or on my bed like a fool. Play/pause/phone answer button works great and i have not gotten any sound complaints from people I call as well.
