The MDR-NC200D headset comes packaged nicely in a compact, soft carrying case for easier transport. Even more convenient is the 1.5m connecting cord, which connects the headphones to audio source (i.e. laptop, tablet, smartphone, MP3 player, etc. -- basically anything with a headphone jack!).
The cord can be unplugged from the headphones, which is really great for the user as not only does that help in prevent cord tangling when jostling around in a bag, but then there is less wear-and-tear and tugging on the cords.
