Overall impressions

If you're the type of person that spends a lot of time on the go and you want to be able to listen to your favorite songs without being disturbed by the surrounding noise, then the MDR-NC300D might be just the thing for you. These earphones will certainly bring you very fast into a world of almost complete silence, whether you're on the street, on the subway or flying long-distance. Of course, we're talking about silence as far as the environment sounds are concerned, because one will also be able to listen to their favorite music at a very good quality level.

However, silence on the go does come at a price, and in the case of the MDR-NC300D, that price is related mostly to the size. Unfortunately, the main control unit is pretty bulky and, despite the fact that the cables included in the package are pretty long, most people might still have a problem finding the necessary space in their pockets or bags for this device.

To make things easier for the user, Sony was kind enough to provide a pretty comprehensive sales package, which includes, among other things, a very nice leather case, providing enough room for storing the MDR-NC300D, a couple of adapters and even a smaller MP3 player (we've tried even a PMP, but there's not enough space for a large-screen device in there).

Last, but certainly not least, we'll also have to mention a different kind of price, namely the actual sum of money you'll have to pay in order to get this thing - 290 USD, which, to be honest, is a bit high, all things considered.
