I bought these on Amazon last year.
They sound pretty alright, but their build quality is nothing short of abysmal. Not so much the earbuds themselves, but the cables. I've had to solder on new 3.5mm plugs on the first set they sent, and the replacement set. The machining tolerances used on the plugs are too open, meaning you'll get plugs that are actually 3.25mm-3.45mm, meaning they don't stay in the ports well and the audio channels frequently cut out. Their tendency to shift also damages the port.
