? The XKDUN CK-660 earphones offer nice specs at a super budget-friendly price with very fun color/design with aluminum housings and a braided cable. We have a pink unit but if you are not into girly colors do not worry because XKDUN sells the CK-660 in many other colors such as: black, blue or violet. Housings have the classic bullet form factor and are made of aluminum which makes them durable and at the same time super light, the back part of the housings has a metal grid that suggests an open-back design. Cable is braided and shares the color pattern of the housings (if you got the black model, cable will be black and white) There is no inline microphone or button control but the stereo plug is 90 degrees angled.

Accessories & Packaging
The XKDUN CK-660 come in a box with a plastic front, inside the box 2 extra pair of eartips are included; eartips match the color of earphones chosen.
Bass & Sub Bass
The XKDUN CK-660 have punchy mid-bass and some sub-bass depth but comparing them they are more punchy than deep. Bass is strong and will cover most music genres without falling into boomy sound. With an EQ, the XKDUN gained a lot of punch and noticeable more depth but started to sound muddy and dark. Under our extreme bass test, the XKDUN CK-660 handled up to 51% of a Fiio E12’s maximum power with exponential gain of punch and depth and reaching a respectable basshead rumble and impact similar to the KZ ATE and VJJB K1S. At the same time there was a general vast improvement of their mids and highs frequencies.

Mids & Vocals
Mids of the XKDUN CK-660 are too recessed on lower frequencies making lower vocals sound too distant and lack energy. Higher mids do not seem as recessed as lower mid frequencies and at the same time do not sound harsh. An EQ was able to remove some recession of lower mids but still they sounded too laid back, while higher mids started to fall into harshness.
Highs & Treble
Highs are able to resolve some detail but lack some brightness. In general they are not piercing but showed a mild sibilance. Applying an EQ, highs opened up a bit and gained noticeable detail, piercing highs still were not an issue but sibilant highs became stronger and more frequent.
The sound that leaks out of these earphones is worse than many average earphones because of their sort of open-back design. They will not be the best choice for library usage.
The XKDUN CK-660 were able to isolate from noises without using extremely high volumes but full isolation will never be achieved unless you crank the volume way up.
The XKDUN are very light and comfortable, they do not generate pain inside the ears. If flexing drivers is something that upsets you, the CK-660 will not be of your liking because their drivers flex with any slight movement.
Response to Equalization
The response to equalization was quite poor; despite enhancing some of their bass, mids and highs also every frequency introduced issues such as muddiness, darkness, harshness and sibiliance.
