"The DK-4001 is a balanced sounding iem that is able to provide extended bass, clean midrange and articulate treble expression. There is a commanding and musical performance with good impact. In addition, the build quality is solid and the DK-4001 utilizes a premium cable that is versatile via the interchangeable jack with quick switching connectors. The Dunu DK-4001 is an excellent flagship from Dunu with its impressive sonic display."

My impressions about the DUNU DK4001 are very positive. It shows a great bass performance offers a musical and detailed midrange presentation and has a treble range that is smooth and controlled. In addition, it comes in a premium looking box that is full of high quality accessories. Everything looks first class, while the build quality of the monitors and of the stock cable with the patented quick switching connectors is absolutely solid! All in all, the DUNU DK4001 is one of my favorite in-ear monitors in this price category.
