These IEMs were built using high-quality drivers and materials and tuned to deliver a well-balanced sound signature. After testing out the QKZ x HBB, I found out that its warm sound signature pairs up really well with songs that are bass-heavy in a mix. The IEMs themselves are placed inside a protective cardboard sheet with machined cutouts and then we get the carry/storage case too—no paperwork of any kind to be seen here. It not only provides the foundation for the mids and treble but it imbues them with warmth and body.

These IEMs, although wired, are designed and built with the goal of just delivering brilliant sound. And so with these caveats in place, I can tell you that the HBB Khan will surprise you, it will make your music fun.

Its very easy to unleash its true sound potential even your typical smartphone can juice it up but with a better dac/dongle it can improved more.It has been manufactured in 4th generation DLP-3D, to create a lightweight, ergonomic, semi-custom design, with an outer panel carved like dragon scales and coated in resin. Firstly, I don't think the sound suits my personal preferences because it has that warm-v shape sound that is very targeted at bass lovers and in shoert bass-heads, but if you're someone who likes the bass you may like the sound. With advances in cable-making techniques and radical approaches to manufacturing, there are now several solutions to this universal problem. Good tuning is free and at the end of the day, we are talking about the ultra budget segment, and just like anything in this world, nothing is perfect.

The top side has the product name and L/R markings if needed whereas the longer side shows the use of matching 0.But as there are so many models that use this connection, it's not a problem to find compatible cables. You can expect these earphones/IEMs to offer good microphone quality and clear audio without having to connect additional peripherals.

Optimized Magnetic Circuit, Double Power​Enhanced high-intensity magnetic circuit greatly improves bass performance. An aluminium faceplate that has undergone CNC processing and now matches the translucent plastic shell has had this artwork directly engraved into it.

The provided tips did not provide adequate isolation, prompting me to switch to other tips for better sound isolation. However, I found the unboxing experience to be lackluster and the included accessories, including the eartips, to be of low quality.
