Your phone has one combined jack for headphones and mic. You want a proper desk mic on one side and your earphones on the other — not a flimsy inline mic you can't position. This 250mm Jaycar splitter takes the 4-pole plug and hands you two separate 3.5mm sockets. Mic on one, audio on the other. Clean signal, no shared channel
