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.

There is also no need to configure speakers for surround sound to match room acoustics. Contrast with earphones
