Apparently, the new Fiio JD11 is the improved Blon BL-03 many wanted. The sound is very close, but the overall build and fit is better. I've owned the BL-01, 05s, mini , all fun with the 05S being very easy on the ears - natural, organic sound.
I am actually comparing the QKZ HBB Khan and the Kbear Rosefinch alongside a 7Hz Legato, Shuoer S12, ER2XR.
The Rosefinch is awesome. Hits harder than the Legato. The Legato is overall more refined and smoother, The Rosefinch has a peak, not necessarily overly sharp, but it is just an incredible IEM for the price.
Compared to the Legato, S12, & Rosefinch - HBB Khan are the overall winner in the overall accuracy of tone. The mid-range and treble are excellent. Tucking in the 200Hz is something you need to hear. It brings a lot more clarity to the lower mid-range. Very, very well-tuned IEM. Except, there is one thing that might be a plus or minus for some listeners - the bass on the Khan. It hits low, and stays low. This might initially put some people off who have been used to hearing a more curved bass to mid-range transition. It sounds like a tuned subwoofer in a recording studio. Except the sub has been notched up so you can get into the music. It could be a bit too much for listeners that want more accuracy.
The mid-range and treble on the Khan - especially when used with quality Spatial DSP or gaming using 3d audio - can sound outright holographic.
To the Rosefinch. These are the real performance-to-value winners and the lowest priced. These should be in the kit of anyone who
remotely likes both sub-bass and mid bass. They punch so hard with an addictive v-shaped tuning. Yes, less natural, and more vivid. They can still sound massive, and their brightness brings a sound reminiscent of going to a warehouse party (one with great PA). But this is a very clear and well-performing driver. It sounds a bit rough/abrasive but just at the fringe, enough to spark more life into sound. Surprisingly good - even after having expectations going in. Easily one of my favourite IEMs. The build is decent! Cable is fine, but I put my old Blessing 2 cable on it.
So about that accuracy thing - it's fine, but consider some music tends to sound more energetic with a tuning like the Rosefinch. So which is more realistic regarding tuning might be relative to the music style & current mood.
Still, the HBB is objectively more transparent in presentation, and
truer to a more baseline room tuning of speakers.
I highly recommend the Khans if you don't have this type of accuracy in another set. However, they do take a bit more oomph to drive, but don't be too discouraged as an iPhone dongle can still power sufficiently and at a solidly loud volume. I got them at 75-80% on an iPhone 6S (great dac amp for a phone) and they sound loud.
You can see hear how they compare, and the Khan is the different one out of the bunch:
