Nintendo headphones

I bought Electoplankton for Nintendo DS from Japan, and it came with some free Nintendo headphones. They have a component on them near the plug, which the lead enters and exists from. It has hinges and looks like it should open, but it doesn't. I can't work out what it's for. Any ideas?

Does it look anything like this? If it is, it reduces electrical interference from other equipment. I've seen it on computer equipment cables, but I couldn't tell you much more about them.

Best answer: Ferrite beads. They can act as a simple lowpass RL filters on the audio line, passing the audio content but blocking RF.

What's the game like? So far that looks like the only title that's worth getting a DS for, at least to me.

Response by poster: It is a game without a challenge, except perhaps one you set yourself (to produce good audio/video). It's very beautiful, but frankly it should have more depth than it does.

Now, Daigasso! Band Brothers - that's a reason to own a DS.

Just for the record, this question was asked before a few months ago. The search keeps timing out on me so I can't find the exact thread but it may be worth looking for if you want to know any more.

I was happy when I saw the previous answers ... the existence of these things always made me curious.
