For those who do not mind something inside their ears, earbuds are great, but, there are many who never felt comfortable. It depends from person to person, trying out an earbud would be the logical approach before you commit yourself.
iPods are primarily portable devices and large headphones basically defeat the purpose of iPods portability. The supplied phones are below average if sound quality is high on ones list, one of the best compromise is to go for something like Sennheiser PX 200, I bought them and reviewed them.
