We prefer earbud style headphones for iPod due to their compact portability. They are much smaller compared to full sized over-the-ear headphones which are too bulky, yet they can still deliver dynamic sound quality. If you want to buy a good pair of noise isolation earbuds, consider the various iPod/iPhone in-ear headphones from Klipsh. These may cost more compared to the typical $5 Coby earphones, but the Klipsh sound quality and patented eartip design with angled nozzles are very comfortable to wear for long hours.
Since ear size and shape differs among everybody, be sure to buy those with different sizes of washable ear tips and flange designs. We prefer in-ear headphones with light and narrow flanges so that you will not even notice wearing them inside your ears. Although in-ear headphones cannot provide as good noise isolation compared to over-the-ear styles, look for designs with soft flexible ear tips that can perfectly mold and fit the contours of your ear canals to form an acoustic seal. This will let you enjoy your music at lower and safer volumes.
