A pair of head-mounted speakers that are positioned over the ears. For listening to music or monitoring live performances, both left and right channels are required. Although often called headphones, when a microphone is included for telephone or video calls, the device is technically a "headset."
Some of the Best Sound
Headphones allow listening to music without disturbing others, but they are also used by discerning audiophiles. High-quality headphones can provide an extraordinary listening experience that is far more affordable than room speakers. Headphones are driven by much lower amplification, and by creating a sealed listening chamber, they can sound as good as or better than stereo speakers costing many thousands. There is also no need to configure speakers for surround sound to match room acoustics. See earphones
