Headphones with XLR connection

XLR

— a characteristic round connector with a lock-lock and 3 contacts (there are other options by quantity). Usually, it is used to transmit an analogue signal through a balanced connection. This connection provides high resistance to interference, typical for professional applications; at the same time, the plug itself has rather large dimensions. In view of all this, the presence of XLR is relevant mainly for headphones designed for use with advanced stationary equipment.
