Headphone Guides

How headphones work, what specs actually matter, and what to look for in different types — from open-back audiophile cans to wireless travel buds.

Headphones look simple from the outside — two drivers, a band, a cable or no cable.

The same pair of ears will rate two "good" headphones quite differently depending on what they're being used for.

These guides explain the parts of a headphone that actually matter, decode the spec sheets you'll see while shopping, and clarify which types and features genuinely affect what you hear.
