KBEAR Qinglong is a brand new pair of single dynamic driver IEMs featuring a 10mm custom-developed dynamic driver unit. The driver adopts a PU+PEEK dual-layer diaphragm that promises quality sonic capabilities. KBEAR has featured extremely beautiful CNC machined 7-series aluminum alloy ear shells that bring you a shiny mirror finish with chrome-electroplating technology.
KBEAR Qinglong delivers mesmerizing vocals, rich and lush vocals that captivate you with their clarity and smoothness. KBEAR has used its years of experience and tuned the Qinglong to deliver a lovely sound with crisp vocals.
While designing the Qinglong, KBEAR tried multiple diaphragm materials including DLC< LCP, Beryllium-plated, Carbon PET, alloy, etc. In order to achieve their desired response, they finalized on PU+PEEK material composite diaphragm with a dual-layered design. The 10mm DD unit delivers a powerful and lively performance.
Voice Coil and Magnetic Circuit are the power source for any dynamic driver unit. Qinglong’s dynamic driver adopts a specially imported DAIKOKU Copper wire high-tension voice coil and N52 NdFeB-based strong magnetic circuit. They help the driver to produce a powerful and dynamic sound performance.
KBEAR has used high-quality 7-series aluminum alloy material to craft the beautiful ear shells of Qinglong. The pair gets a premium mirror finish with a chrome-electroplating process. The shells have got an ergonomic shape and design for a comfortable fit.
In order to deliver top-quality sound performance, KBEAR bundles the Qinglong with a high-purity 5N OFC (Oxygen-Free Copper) silver-plated cable. It uses premium aluminum alloy metallic shells on the Y-splitter and the termination plug. The cable has 2-pin 0.78mm connectors and a 3.5mm single-ended termination plug.

What’s in the box
I would like to thank Keephifi for providing me with the review sample of KBEAR Qinglong (no affiliate link).
The bass is tightly controlled and clean. It leans slightly more towards the mid-bass and then starts to fall off as it transitions into the lower midrange. Qinglong’s sub-bass is pretty satisfying and although it has a light rumble, the bass overall extension is good.
The mid-bass and upper bass are a little less saturated than I prefer and while kick drums are punchy enough, I find that bass guitars and synth bass sound distant and at times barely audible. This is probably the underlying cause of the lack of engagement I experience at times with the Qinglong. It feels as though it’s lacking soul and groove. On the upside, the bass doesn’t bleed into the mids.
Bass is there, well-defined, and impactful, but I’d loved to hear more low-mids as I couldn’t get my usual kick on the go. That said, the Qinglong still managed to deliver deep sub-low, proof that it’s more about tuning than performance issues.
Qinglong has a fairly forward midrange and above-average clarity. The lower mids are on the cooler side of the scale. Male vocals sound clear and articulate but lack a bit of power and body. However, in general, vocals and instruments sound fairly neutral and accurate. Guitars sound great making Qinglong a good choice for orchestral and acoustic genres.
When it comes to instrumental presentation, piano tracks maintain a good harmonic balance with the lower treble. However, when it comes to the body behind each note, there is a sense of each note lacking an immediate sense of attack. Similarly, guitars sound harmonically balanced while having a textured and detailed presentation.
The lower treble is energetic, so cymbal hits are easily noticed. Treble can also be discerned easily, while the immediacy of attack and decay of each cymbal hit is relatively natural sounding. So each hit sounds immediate while having a healthy amount of splash and sizzle.
However, when it comes to the weight behind treble instruments, or harmonic overtones found in the treble frequencies, there is a lack in the overall weight. While the treble notes can peak through the rest of the frequencies, the lack of treble weight makes it less emphasized even when treble sparkle can still shine through.
Build quality is excellent, comfort is superb, and the sound is good for the money, with good mids and vocals. When paired with a quality source you can definitely feel how well the Qinglong scales in sound.
The downsides? If mids are praiseworthy, lows and highs aren’t as magical. If they ain’t bad, they are not amazing either, particularly compared to their mid-counterpart.
