"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."
