Best iPod classic accessories?

Hey guys,

I've got my 160GB ipod classic last week and i'm wondering what are the best accessories to get for it?

I didn't have time to search before posting this so apologies if this query has been repeated.

I live in the UAE btw and i can't seem to find any accessories over here for the "Classic", it's all for nano, touch, etc.

So, i would really appreciate your tips as i'm intending to order through amazon / ebay or any trusted website you might recommend.

PS: My primary use will be for gym, any recommended armband brands? Or durable headsets for sweat and all (affordable i.e. not beats range)?

Thanks in advance,

Kareem
