Five Driver Hybrid Configuration
The acoustic team at NiceHCK has got years of experience in designing single and multi-driver earphones. With that expertise, they have designed the latest M5 with a five-driver hybrid configuration housing a 10mm dynamic driver and 4 balanced armature drivers on each side. The pair has got professional tuning adjustments to present a rich and lively sound with a clean background.
Professional Crossover Technology
Experienced acoustic engineers at NiceHCK have arranged the five-driver configuration in a three-way frequency division using professional crossover technology. This allows the drivers to perform perfectly while maintaining low distortion levels.
Adjustable Tuning With Swappable Tuning Valves
NiceHCK M5 has got tuning valves placed at the faceplate area of the M5 cavities. These are swappable, the pair comes with three sets of tuning valves, Grey for balanced tuning, Blue for Heavy bass, and Red for enhancing treble performance with the M5.
Advanced 3D-Printed Ear Cavities
NiceHCK has adopted an advanced 3D printing technology for the ear cavities of M5. They are made up of high-quality imported resin material. With this high-tech 3D printing technology, the cavities are crafted with great levels of accuracy and precision. The pair also has aluminum alloy faceplates for a premium and glossy finish.
Ergonomic & Comfortable
NiceHCK M5 adopts a lightweight and ergonomic design. The pair is designed to provide a comfortable and firm fit for most uses, allowing them to have a comfortable listening experience with the set. Lightweight shells enable the users to wear the set for long hours.
WHAT'S IN THE BOX
I took them mainly because I like them aesthetically (yes, even the huge screwdriver), and I was interested in the idea of interchangeable tuning.
From an aesthetic point of view not
I can complain: they have a nice packaging, a nice cable, a nice 3.5 jack, a nice transport box.
From the sound point of view, they have a medium-low sound quality, lower than the average of the IEMs in this price range.
The definition is discreet, but the sound is not vivid, it is not impactful, it is set back (it is as if there was a filter in front, which prevents the sound from expressing itself).
The bass sounds muffled too.
The stage is quite narrow.
To sum it up: sonically, more is expected from IEM at this price point.

Still awesome cable(i have it for my HD600) BUT not compatible for Meze 99 Neo and 99 Classics.
They took a little longer to burn in than the last IEM's I purchased, but are a huge bang for buck product.
My preferences don't seem to line up with most experts/reviewers. I found the T4 + to be a nice relaxing listen with plenty of detail.
I fell for the YouTube review as well, and wish I had waited for other opinions... These have an awful echo with certain frequencies; you can literally hear sharp sounds reflecting and pinging inside the cans. And this site's return policy doesn't even last as long as the burn-in period stated in the user manual.
I took off the beautifully crafted headband and used it to fix my Hifiman HE-4XX.
It follows a mild v shaped but it's very well done, at $55 it punches above it's own weight, I very much recommend it.
Comfortable, sound great. Not too expensive. Exactly what I wanted.
I purchased the BTR7 for the increase in power over the BTR5 and the 4.4 Pentacon connection.
While the bulk of my listening is portable audio, the extended battery life of the BTR7 means I can use it to take high resolution audio and feed it from the BTR7 directly into my HIFI system pure and direct… listening at concert levels…. Well till my neighbours complain and I get a grapefruit through the window…
The thing I miss the most on the BTR7 is the lack of a clip or holder to secure it to yourself while you are on the move…. This will force you to get inventive and sort out some sort of lanyard holder or in my case modifying an old multi tool pouch so I can clip it to my belt.
The battery life is reflected in the way it is used, if you are driving planar headphones through the 4.4mm connection… you might get 3 or 4 hours…. Listening to IEM’s through the 3.5mm connection and the battery life will double…
The other feature I found is the support of MOA encoded music from Tidal… this is awesome and something I enjoy listing to…
Interfacing with the BTR7 menus is best carried out using the Fiio Control App, which you can download along with firmware updates from the Fiio website.
I am very pleased with my purchase and can happily recommend the BTR7
Now I am a truck driver with little or no budget for IEM’s. In my world IEM’s are very much a consumable product with a limited life expectancy.
I mention this as the most expensive IEM I currently own would be the Xenns Mangird Tea 2, and covet the Thieaudio Oracle.
I have purchased a number of budget offerings over the years, and I had the HBB Mele which I enjoyed very much, sadly on one particular work site these expired, getting caught up in an argument between gravity and some bulldozer tracks.
I liked the concept of the Khan, with its dedicated low end driver and its tame manners in the higher frequency. I really was looking forward to there arrival from Linsoul.
The IEM’s themselves are light, manufactured from a plastic resin, the body of mine is dark almost black, and slightly translucent (not sure thats the right word… I and sure if you held a torch up to it you could see some of the internal anatomy).
For me IEM’s are about being on the move, doing other things, getting the stuff of everyday life done.
I might be mowing the lawns, painting trellis, working in the garden, vacuuming, washing the dishes or at the gym.
All those things you spend your day doing because you are busy.
So if I’m at home I am normally using the Xenns Mangird Tea’s, if Im at work I’m using something much more affordable (because of gravity and bulldozer tracks etc)
Enter the QKZ + HBB Khan….
I upgraded the cable to the QKZ Q1 Max cable, this comes with a choice of interchangeable input plugs, the 2.5mm balance, the 3.5mm stereo and the 4.4mm pentacon…
I have a seperate review on this cable, if you have not yet fallen asleep.
The other modification I apply to all my IEM’s are the Symbio Hybrid Tips which you can easily find on Amazon. These tips give me the reliable seal of a foam tip with the durability of a silicone shell, the perfect partnership.
I watched and have read a number of reviews on online prior to purchase, but as I say I’m a HBB fan-boy and enjoy the process of him talking me into my next purchase.
It is difficult to find a review on line that praises the virtue of the HBB Khan. Reviewers are comparing it to all assorts of IEM’s some worth hundreds of dollars and in one case thousand of dollars… critiquing the high-end being rolled off or the mid range been a little thin….geez are we listening to the same IEM?
I can honestly say the sound of the Khan is truely shocking… there it is you have wasted the last 10 minutes of your life, but for me the Khan is truely a wet fishing the face….
Its like the 1st time you hear your favorite song on a good car audio system, with unbelievable bass rich mid range tones and clear airy highs that are bout to become sibilant… but never do… all the time the thump and rumble of that bass…
Thats the signature of these IEM’s they remind me of good quality car audio…
I found myself listening to music like Angel by Massive Attack… why? Because its fun…. with the Khan. I was listening to a random play list on Tidal and Flowers by Miley Cyrus came on…. I nearly dropped my paint brush…. good grief…. the bass that hits about 30 seconds in was so unexpected…. These two pieces of music are not my normal go to sounds, but the Khan’s delivery is massive… everything is there, the bass, clear vocals and the high end all there and crystal…
I find myself listening to all my music as if truely hearing it for the 1st time, with all sorts of surprises throughout the recordings… if this sound is as bad as some reviewers have made it out to be… then ignorance truely is bliss.
The live recording of Simone Kopmajer at Heidi’s Jazz Club is a stripped back performance with a drum kit and brushes, a saxophone, double bass, a piano and Simone’s voice… there is no where for an IEM to hide any flaws here. The string plucks on the bass are strong and in your face, yet the piano is clear and present in the music… Then Simone, she starts to sing… it seems very intimate and personal… As I say The easiest way to explain the experience is like good car audio… with a sub in the boot (or trunk) and great speakers in the doors with the whole thing tuned in and setup for your listening position.
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.
I have never listened to $1500 or $2000 IEM’s and I accept that I don’t know what I don’t know.
Or if you prefer my experience defines my reality. And so with these caveats in place, I can tell you that the HBB Khan will surprise you, it will make your music fun.
While the QKZ + HBB Khan may not technically be perfect in every way, at $40.00usd the Khan will make a lot of much more highly regarded IEM’s, well, just seem plain boring.
My second set of earphones, and its good, better with the open eartips or other eartips opener
Looks like a very bassy IEM. Ian Fann has the only squig link on these so far. If Linsoul decides to put them on sale like their competitor ($10 coupon), I might jump on them. These should go with my EA 500 from Simgot for more bass.
Got mine through Amazon for $70. Linsoul has an even better price. If you pass these up, it’s your fault. The Simgot EA 500 can compete with any single dd up to $200. Check out Tone Deaf Monk’s review.
