The AD 4.4 / XLR-4 adapter cable serves a specific function in high-quality audio setups, allowing users to connect headphones featuring XLR 4-pin plugs into headphone amplifiers that have a 4.4 mm Pentaconn output socket. Measuring approximately 25 cm in length, this adapter cable ensures a pristine audio connection through its use of a symmetrically wired Pentaconn plug on the amplifier side, which is produced by NDICS. On the headphone end, it features a symmetrically wired XLR 4-pin socket manufactured by Neutrik, renowned for their reliability and quality in audio connectors. The cable itself is the balanced high-end cable from the Solitaire P headphones, which guarantees that the adapter does not compromise on sound quality, preserving the integrity and clarity of the audio signal throughout the connection.
