Furthermore, about the Treble…​Cymbals have a nice “chisk” to them and trail off with enough volume while not sounding weird to me. Piano and sax sound “natural” to me. Honestly, I don’t have a ton to say about the treble region. I think it is very nicely done considering the asking price and the library of music this set was catering to. Again, there is still a smoother and less crisp, less separated and less defined leading edge to instruments though I hear good enough clarity to easily satisfy me.

As i mention in the pros, these set was suitable for gym session. Because my gym playlist has mostly EDM or bass heavy music, when using these with a bluetooth adapter, it was like a match made in heaven. It just makes we want to be active. Sure, I may lose some of the smart feature that a dedicated TWS can bring, but that’s the price I’m willing to take. Which one to choose?​Personally, I do enjoy the QKZ X-HBB a bit more. It simply is closer to my target and what I prefer when listening to music. However, I can’t say that it isn’t extremely close considering all that the Zero does well. The difference for me lies in the fuller and more dynamically expressive sound of the XHBB, with its more robust and deeper low end and the way vocals come across more saturated in the “feels” department. This is in no way a rebuke of the Zero and I want to make sure there is no misunderstanding. I thoroughly enjoy that set. It is a budget Marvel in my opinion, and I do believe that it will be some time before we see another which is so well executed.Enhanced high-intensity magnetic circuit greatly improves bass performance. With HBB’s special tuning, the earphone reproduces crystal clear sounds with enough bass for people who want to crank it out a bit, yet still be able to hear every instrument and vocal details of what is playing through their headphones. It is a good choice for R&B, DJ, stage performance, metal... This is starting to turn into a book, so lets end this review by saying the bass on the Khan is not going to rattle out your fillings its not going to blow your head off, what it will do is allow the bass to get the attention it deserves and it will do this without sacrificing the vocals or the high end. The build is actually much better than I would have expected. Truthfully this set is built solid! It appears that it was constructed from two pieces (Faceplate & Shell) glued together. QKZ also added what appears to be an aluminum ring around the Faceplate which is a nice touch. The nozzle is sturdy and golden in color with a nice lip for holding tips as well as some scored marks around the lip. The grill is also not some flimsy cheap mesh grill but is solid & all metal which adds a bit of a premium flare.

There is a ton of texture to bass guitars and the overall bass in general. I think it strikes a nice clean, melodic, authoritative and textured balance. “ Feelin the Miles” by The Wilder Blue shows off that guttural bass guitar like a budget champ. Or “ Heavy is the Ocean” by Bush on their brand-new album. People just trust me that XHBB absolutely kills it. There is nice depth to the bass while chaos is playing around the bassline. Pretty darn good. Midrange Mids in general I think treble extension is slightly in favor of the XHBB while the Lyra has a hint more emphasis, especially in the low-treble. The soundstage actually has more depth and more of a holographic sensation on the X-HBB with a slightly more fun and dynamic sound. Still, I’d say the Lyra has a wider stage. The overall timbre and tonality of the Lyra has an airier quality to it with better spacing and a touch more resolute overall. A Tough Call… In terms of handling, the Blon is much easier to move than the HBB Khan, which requires much more power to shine on par with the BL-Max. The QKZ x HBB IEMs have a detachable silver-coated cable that effectively reduced the stethoscopic effect. The XHBB has a warmer tonal character yet with good extension and dynamic expression both ways for an ultra-budget iem. This is a V-shaped iem with a definite emphasis in the bass region. I hear a semi-smooth replay with a non-fatiguing sound yet still with some defined edges to notes and an energetic warmth which sounds decently compelling.When listening to pianos such as Hania Rani’s Glass or Yann Tiersen’s Comptine D’un Autre Ete – L’apres-midi, despite the warmer note weight, all the information is kept, turning the replay more “musical”, as it’s usually referred as. The separation and layering are just enough to not feel like a creamy potato mash and given that, there’s not much I can complain about it given the price range. Imaging​Imaging is pretty good. Nothing jumped out at me as a problem. Most of my music isn’t so chaotic that the XHBB can’t keep up and position well. I can pretty easily locate everything within my music putting the X-HBB above average to me. I’ve heard sets that are horrible in this area and the XHBB isn’t one of them. I’d say nothing is out of place or blended, which is all that we should be asking of this price tag and tuning. There is good enough clarity to distinguish decently etched out elements of a stage.

Resolution is more focused on macro-dynamics rather on micro-detail retrieval on how it portrays it overall definition. But micro-details retrieval of this set is somehow decent but not the best out there. Timbre is more on a warmer side of tuning. The earphone comes with a standard detachable cable with optimized recessed 2Pin connector for longer lifespan. Silver-plated cable was selected as material to avoid stethoscope effect. The detachable features makes it easy to connect the device to various devices and ensures more possibilities for those who love to change things up. It provides convenience should your needs change later on. That's where the Khan comes in. This IEM is so much different to listen to, I feel like a kid again. The subwoofer really brings out the bass in a way that just makes you want to dance. And even though the tweeter driver is small, the soundstage is surprisingly wide. With times of experiments, QKZ acoustic engineers eliminated ordinary diaphragms and eventually selected the unique 10mm Titanium-Coated Diaphragm to deliver a detailed, accurate sound that is different from any other product in the market. When comparing these earphones to the KZ ZSN, I found the vocals to be more pleasing, with rolled-off treble peaks that lend themselves well to extended listening sessions and podcasts. Although the KZ ZSN has excellent sound separation and layering, the QKZ handles bass better, providing a more inviting and enjoyable listening experience.

Otherwise, the sound department is very good. If you're thinking about getting these, you should definitely do so, but be aware of the minor discomfort. All of the other IEMs I mentioned are more comfortable.. Zero’s tone and timbre make this budget earphone stand out in the crowded budget space. The naturalness and tonal accuracy found here are rare for something in this price range. QKZ x HBB Sound I also had a volume problem. I set my phone to maximum level and still thought the volume on KHAN was low although when I use my (Moondrop Aria/ Tinhifi T3 plus/ BLON 03), the volume is sufficient for me at 70-80 percent. I think it is a cool thing to see a collaboration with one of the lower budget brands in chifi and one of the bigger names in the hobby. This is good on many fronts, but the best part is that we “the consumer” actually reap some rewards of such partnerships. With this recent string of collaborative efforts of late, I think there has been an evident spike in quality within the budget sector in general. Competition and standards grow, and eventually better gear hits the market. That is how it seems anyhow. This was fun…
