Introduction

Dunu is a Chinese company established in 1994. They specialize in the production of in-ear monitors (IEMs). The Titan and DN series are very well-received. Recently, they have released their flagship product in the DK-4001. I would like to thank Dunu for the review unit of DK-4001. At the moment, the DK-4001 can be purchased from Dunu or Penon Audio.
