This interconnect cable has a 2.5 mm TRRS plug and a 4.4 mm Pentaconn plug.  Most commonly used for connecting 2.5 mm TRRS output from a DAP audio source to a DAC or amplifier with a 4.4 mm input.  This cable transmits a balanced stereo signal and can be used biderectionally.

The Pinout is as follows, also pictured above:

2.5 mm Tip, R- :  4.4 mm Ring 3

2.5 mm Ring 1, R+ : 4.4 mm Ring 2

2.5 mm Ring 2, L+ : 4.4 mm Tip

2.5 mm Sleeve, L- : 4.4 mm Ring 1

All cable options include excellent dielectric insulation and shielding to reject EMI and RFI.

This Cable is available in OFC, SPOFC, OCC & Pure Silver.
