Headphones with 6.3 mm jack

6.35 mm Jack

— the largest type of audio Jack found in modern technology. Outputs of this type are found mainly in stationary audio devices — they are too bulky for portable gadgets, it is easier to use a 3.5 mm mini-jack there. At the same time, the 6.35 mm jack is considered a more suitable interface for professional and audiophile equipment: it provides a more reliable connection, greater contact density and, accordingly, less likelihood of interference. Therefore, although relatively few headphones are equipped with their own Jack type connector (mostly premium solutions), many models with a 3.5 mm mini-Jack plug are equipped with a 6.35 mm adapter; they are also included in this category.
