A marvelous new collaboration of HBB and QKZ Audio is ready to bring fresh vitality to the HiFi community.
With HBB’s（HawaiiBadBoy from “Bad Guy Good Audio Reviews”） knowledgeable and resourceful experience in IEM testing and review, excellent potential of Khan was made possible as he takes excellent care of Khan’s tuning. After HBB’s skillful ear, your Khan is transformed with a balanced tone that sounds just like honey.

With this high-tech style IEM, you will hear pure and warm music as if the artist is right in front of you.
10mm Bass Dynamic Driver+7.8mm Mid&High Dynamic Drivers
Double the number, double the power. With two dynamic drivers, the sound of Khan precedes any ordinary dynamic IEM. It’s big 10mm driver contributes to the warm and immersive low-to-middle frequency while the medium 7.8mm diaphragm adds airy treble to the plate. No matter what your music taste is, instrumental or vocal, Khan is well-qualified to deliver. Furthermore, with audio purity intensified by LCP liquid crystal complexes diaphragm, Khan is the uncarved jade completely faithful to its input.
Great with Mobile, Superb with Amplifier
With mobile never out of our site, the IEM you are looking for should work well with your phone. Luckily, Khan has a low impedance of only 10Ω, so even mobile devices like phones or MP3 can power it well. And the sensitivity of Khan can reach as high as 117+3dB, letting you savor every detail in your favorite song. Of course, if an amplifier or more professional devices are introduced, Khan’s performance will reach the next level.

The materials and technology used for Khan are unthinkable compared to its peers. To give you the purest natural music, 4th generation industry-level DLP-3D printing is adapted to make the acoustic conduits in greater precision.

Sound quality description
In this review, I use the standard eartips size L and drive it with the FiiO M15.
QKZ x HBB Khan has a U-shaped sound signature.
Please see here for detailed reviews on sound quality.
Lows / Bass
The QKZ x HBB Khan's low frequencies feel quite weighty, but lack a bit of depth.
Drum kicks feel quite heavy and have impact, but lack rumble, lack realism, and sound shallow to me.
The electric bass, while not bad in blackness, is also lacking in sink, lacks spaciousness, and feels a bit short on musical contrast.
The bass is quite emphatic in quantity, but there is little to see in terms of quality. It may satisfy low-frequency lovers to a certain degree, but it will not satisfy true low-frequency enthusiasts. And for those who don't like low frequencies much, it is probably too much at more than the proper volume.
The midrange of the QKZ x HBB Khan seems to be tuned for neutrality, so the textural accuracy is almost accordingly adequate. Transparency and resolution are not bad, but they are heard in darker positions and add a bit more seasoning to the vocal and instrumental sounds. It is not lush in the least.
Overall, the sound is soft, with only guitar edges standing out as strangely glossy, and female vocals are adjusted to sound a little uppity and sexy with an emphasis on breath and consonance, making the sound more consumer-like than audiophile-oriented.
Vocals are dry and raspy, with a slightly lispy and nasal sound, as if she had a cold, and her throat sounds bad. The snare is not solid, does not sound well bodied, and lacks dynamism. The midrange has a poor sense of focus and is yawn-inducingly boring to listen to.
Linearity is decent, so it's probably a relief that the sound image is fairly good in terms of consistency. The not-so-good midrange, combined with the low-frequency influence, gives the overall atmosphere a dark, dull sound.
Highs / Treble
This is the most decent sound section of the QKZ x HBB Khan.
The definition is adjusted to a fairly good level to balance the low frequencies, and despite the overall structure being dark and lacking in crunch, making the center of the music buried and difficult to understand, there is no sense of lack of detail.
Sibilance is tuned a bit strong, but the low frequencies hold it down so that even those sensitive to high frequencies will not find it harsh.
Extension is a little less than standard, but the overall sound is dark and colorless, so the hi-hats are subdued and their presence is quite diluted.
Sound quality general comment
If you like dark, heavy sound, the QKZ x HBB Khan may be at least worth considering, but there are quite a few similar-sounding earphones in the price range that are much better than this one, so there is almost no need to choose this one.
Sound quality features
- Elegant and chic
- Sound field with a sense of depth
- Good original sound fidelity
- Massive low frequency range
- Gentle on the ear and comfortable to listen to
- Resolution well above its price
- Front localization
- Dark, poorly audible midrange
- Unnatural texture
- Sound too round, lacks a sense of build
- Poor coloration
- Low frequency range lacks realism for its weight
- Lacks a bit of extension in the high frequencies
The QKZ x HBB Khan is IEMs with a dark, heavy U-shaped sound signature. If you are looking for IEMs with a rich low-frequency sound, it is worth considering, but there are many better low-frequency models available, so there seems little need to choose these, which is not suitable for everyone among low-frequency earphones and is not of high quality.
