At home, almost any good headphones will do. They can allow you to enjoy a late-night movie without disturbing your sleeping spouse or listen to music while the kids run amok in the background.
Portable headphones let you take the show on the road. If you’ll be using an iPod or portable DVD player in a crowded plane, consider a noise-reduction model that can diminish unwanted ambient noise.
Some headphone models, such as closed, over-the-ear headphones, tend to block outside noise. So do insert-style earphones that are inserted into the ear canal, forming a seal against outside sounds, much like an earplug. Active noise-canceling models use battery-powered electronic circuitry that can reduce extraneous noises to various degrees. Use this headphone guide to find the right pair for you.
