This adapter allows you to plug your balanced XLR (4 pin) cable into any audio player with a 2.5mm balanced output.
Neutrik balanced XLR 4 pin female connector
2.5mm TRRS balanced plug. 3 options available.
Compatible with Astell&Kern AK70, AK240, AK300, AK320, AK380, AK100ii, AK120ii, Fiio X5 3rd Gen, X7 (with AM3), Onkyo DP-X1, Pioneer XDP-300R, Cayin N5, The Bit Opus #1 DAC, Luxury and Precision L3 DAC, and other devices with a balanced 2.5mm output.
The 2 feet and longer lengths allow you to leave the heavy and unwieldy male/female XLR connection on your desk, side table, couch, etc. while you hold and control your digital audio player. There is much less strain and pressure on the socket since the weight of the XLR connectors is not pulling on it.
