These headphones sound great, as you'd expect from a mid-range Sony pair. They're also comfortable in the ear, with three different sizes of tip available interchangeably.
I'm slightly puzzled by the accessories and the unnecessary packaging, however. I don't see why the travel case has to be so much bigger than the headphones themselves, and why it needs two pockets. I don't need a separate winder for the headphone cord, though I can at least see how others might find that useful. The packaging-to-product ratio is way too high; the box could easily be a quarter of the size. At least it wasn't too difficult to open.
However, the true test of the headphones will come in a year's time. I've had many a good-sounding pair of headphones become unusable after about that length of the time, usually because the connector wiring has worn down and only one earpiece produces sound. That's what happened to the headphones I was using before these ones (by Creative). The build quality does seem slightly above average, and the L-shaped connector should prevent some wear and tear, but I can't give five stars until I know that they are as durable as they impressive.
