🎧 The VJJB K1s are part of the vast catalog of VJJB earphones, as usual the brand designs very interesting products from either aesthetics to technical specifications. The VJJB K1s makes honor to the brand reputation and offer a very original form factor, high quality materials, interesting technical specifications and a large array of accessories included. As you might have already seen the housings of the VJJB K1s have a pretty original design with a special form factor that could resemble the end part of a trumpet (we might have a kids cloud-watching imagination though).
Housings are very solidly built with ceramics as well as every detail like the cable bifurcation and cable plug section (except the microphone/control). Construction quality does not limit to the housings, the cable and inline microphone/mic feel well manufactured too.
The ceramics housing add some weight to the earphones which gives the sensation of durability, at the same time they are not heavy.
The ceramics housing add some weight to the earphones which gives the sensation of durability, at the same time they are not heavy. The narrowing back part of the housings is something that we have previously seen on other earphones such as the Sennheiser CX200, Rock Zircon, UiiSii Hi-705 or even on the Xiaomi Mi Pro HD (to some degree) and is usually a design resource to provide an easier way to grab and handle the earphone housings. Many times we found that Chinese manufacturers declare contradictory technical specifications, like what we saw while reviewing the Joyroom JR-E102 or the Somic MH403.
The VJJB K1s could be one more to add to the list, in some places the VJJB K1s model is said to hold a 9.7mm dynamic driver while the user manual that came inside our packaging clearly declares that it has a double 6mm dynamic driver, phyisical dimensions could fit either so there is no certain way to know which one is true unless the units are disassembled. The VJJB K1s can be bought in black, white or gray.

Accessories & Packaging
The VJJB K1s come inside a hard and thick cardboard box that can be used as a storage box, inside VJJB provides 6 pair of extra eartips and a carrying case.
Bass & Sub Bass
The VJJB K1s show punchy mid-bass and deep sub-bass right out of the box that does not sound too boosted as to seem boomy or dark. Bass has energy, is fun and well balanced between mid-bass and sub-bass. Their bass will make happy most listeners without much issues.
Bass has energy, is fun and well balanced between mid-bass and sub-bass.
With an EQ the VJJB K1s are able to enhance their bass response immensely becoming very strongly punchy and deep with even some very marginal rumble.
On our extreme bass tests the VJJB took 47% of the maximum power of a Fiio E12 portable amplifier (when using a custom basshead EQ and setting on the bass boost of the amplifier while on high gain) and resulted in an extraordinary empowering of sub-bass depth and mid-bass punch allowing them to reach some respectable basshead impact and rumble above the KZ ATE but still not up to the level of the Top Basshead charts such as the Plextone X41M, Xiaomi Mi Quantie Pro Hybrid, Elecom EHP-CA3580, Sony MDR-XB50AP, Puma Bulldogs, KZ ZST, Senfer 4in1, Pioneer SE-CX8 or Sony MDR-EX800ST.

Mids & Vocals
Mids of the VJJB K1s sound clear but do exhibit a mild laid back sensation depending on the song and male vocals tone, higher mids are a bit harsh at times. An EQ removes some of the sporadic laid back sensation but things can quickly fall into boxiness, also harshness becomes much stronger, so it is a wise idea to not enhance higher mids.
Highs & Treble
The highs of the VJJB K1s have brightness but they are not able to resolve a great amount of detail. Piercing highs can be frequent with high notes and a bit of sibilance is present but not strongly or too disturbing. Applying an EQ, the VJJB gained a big amount of brightness and some detail, piercing highs remained similar as when uneqed but sibilant highs became stronger and more recurrent.
Sound leaking out of these earphones is low, the K1s offered a better performance than most average earphones. Still sound can be perceived by nearby people.
Once again, the VJJB offer better than average performance regarding sound isolation capacity, allowing to use medium volume and still effectively reduce surrounding noises.
The VJJB K1s offer exceptional comfort with super easy to put in and grab housings, light but robust construction and no pain inducing fit. They can be used for several hours and no discomfort will be generated.
Response to Equalization
The response to equalization of the VJJB K1s was good but with some issues enhanced. Regarding bass response they showed an incredible gain in punch and depth; mids and vocals improved on the lower mids frequencies but higher mids became very harsh and somewhat boxy; high frequencies obtained a great amount of brightness but detail was not benefited as much and sibilant highs were noticeably stronger and frequent.
