Know before you buy

Yes, the Code 23 is engineered for dual application. Its versatile design and interchangeable connector system make it compatible with a wide range of both in-ear monitors and over-ear headphones.
These are modular systems that allow you to swap connectors and terminations without needing to replace the entire cable. ConX handles the IEM-side connections, while TermX allows you to change the plug on your source device, such as switching between 3.5mm, 2.5mm, or 4.4mm.
While the 16.5 AWG construction is thicker than standard cables to ensure low resistance, it utilizes Effect Audio's UltraFlexi insulation. This material is designed to keep the cable manageable and comfortable for daily use despite its robust internal structure.
This complex geometry, which includes a central solid core, is designed to stabilize electrical characteristics and improve signal resolution. By using a proprietary mix of wire sizes, the cable is able to precisely shape the frequency response for a more refined listening experience.
