History

Headphones are the direct descendant of the old-fashioned telephone earpiece. By 1920, the first model had emerged to use dual earpieces connected by a headset. Headphones have improved along with general advancements in audio speaker technology. The basic structure of headphones, however, has remained the same, with the exception of earbuds.

Buying Guide

There is tremendous variation in price, comfort and performance among headphones. Some general features to consider include open-back headphones with ear-pieces that allow in ambient sounds, noise canceling models that electronically block out constant background noise, and wireless transmission phones that provide freedom of movement. Sound quality must be heard to be assessed, so mind the return policy, whether shopping online or off. Also, some manufacturers, including KOSS, offer no-questions-asked warranties for headphones.
