These earphones are mostly built using high precision engineering and use S316 stainless steel housing to decrease harmonic resonance.
The connectors are precise and fit with a secure snap fit. The shells are able to rotate 360 degrees so should help with all manner of fit preferences and ear shapes.
Cable jacks have re-enforced rubber to help with any excessive cable flex. They are made of a strong metal and have the models serial number printed on them.
Shells have mesh covered nozzles to protect from earwax and debris.
I am happy with the build quality and manufacturing quality of the Dunu DK-3001 hybrid earphones.
Digital Audio Player Pairings
Pairing with the Astell and Kern AK380 Copper player
Energetic and articulate pairing with the elegant Astell and Kern AK380CU flagship player – dynamic with decent synergy.
Pairing with the newly released Sony NW-WM1Z digital audio high end player
Warmer more natural signature, wider staging presence attained.
Driving the DK-3001 was quite easy and I suspect even a phone would be able to give a good experience with this earphone due to its low impedance of 13 ohms.
As the AK380 had a more energetic presence than the warmer presence of the Sony NW-WM1Z player I felt the synergy with the DK-3001 earphone was more suited to the Astell and Kern player.
The rest of the review is based on the A380 pairing.
