ddHiFi DJ30A 4.4mm Male to 3.5mm Female Audio Adapter - High-Quality Balanced to Unbalanced Converter for Headphones, DACs & Audio Equipment (Perfect for Sony, FiiO, iBasso & More)

It is still Single-Ended

Thanks to the unique simulated 3.5mm connection, you can rest assured to use!

Why do we need it?
When the device only has a 4.4mm output port and you want to use 3.5mm terminated earphone. The uniqueness of the design is to simulate the 3.5mm single-ended connection, rather than short-circuiting the negative poles of the left and right channels.
