ddHiFi DJ65M 6.35mm to 4.4mm Balanced Audio Adapter - Premium Headphone Connector for HiFi Systems, Studio Equipment & Portable DACs

Note, this is a single-ended signal adapter
As shown in the image, when converting 4.4 to a single-ended signal, it can be understood that only half the power is used, with the signal coming from the device's L+ R+, and the 5th node of the 4.4 socket being used as the G return. Caution! The balanced 4.4 signal cannot have the L- R- shorted as G-, as this will increase the device's load and could even cause damage.
