How it compares to KZ Castor Harman:

• Less sibilant
• Slightly brighter sound. More energy past 8khz
• Inferior detail retrieval due to it's tuning

What I like:

• The dip in the presence region makes it sound less fatiguing, though detail retrieval is affected in turn
• Inclusion of switches to fine tune the sound to your liking, though it does very little to the sound

Bottom Line
Polaris is another strong contender at the $10 price point.

What I like:

• Sub-bass focus -> no bass bleed into the mids
• Lean note weight, or having no warmth -> cleaner upper mid-range
• Presence dip -> no sibilance
• Moderate brightness -> less fatiguing

If you came from the EDX Pro, this is what you can expect to hear:

• Less bass
• Less perceived clarity from its less peaky treble (only if your ears can handle the EDX Pro's treble)
• Smoother sound overall
• Better detail retrieval

The EDX Pro X has a safer V-shape tuning, making it a much easier recommendation compared to its predecessor. If you couldn't try both IEMs before buying, get the Pro X instead.

Let's skip the bs and jump straight into how they sound.

Sound​

They sound very similar to the KZ Ling Long (LL) which I will be comparing them with. The Changle is tested using Dunu S&S eartips with JCALLY AP7 and Galaxy Note 9.

Bass​

Sub-bass is more pronounced than mid-bass, just like the LL. In fact, both sound identical in terms of the quality of bass. It does not sound punchy and energetic because of the lack of mid-bass.

Mids​

Midrange is clean and natural sounding. Lower mids are more lush than the LL, by just a bit. There is a boost in upper mids around the 4k range which I don't like.

Treble​

One word - BORING. Treble is quite laid back. Zero sparkle from cymbal crashes. I am extremely treble sensitive and find the treble on the Wan'er to be harsh, but Shimin Li OG to be perfect for my ears. Even with my treble sensitivities these sound dull.

Technicalities​

Detail retrieval are identical to the LL, which are average. Soundstage is unusually poor - they are much narrower than the LL, and details at the center stage sound distant, as if a surround sound mode is turned on (I don't know how to describe what I'm hearing).

Conclusion​

These are worse than the KZ Ling Long in almost every aspect (except the looks) despite being twice as expensive. The Ling Long is 30 MYR ($6.5) while the ChangLe is 60 MYR ($13).

Introduction​

Another sub $20 iem. ** checkouts instantly **

Sound​

I would describe the Shanghua as Neutral but with SLIGHT HINT OF BRIGHTNESS WITH MANY EXLAIMATION MARKS!!! I will be comparing it to the Tanchjim Zero as they are quite similar to each other.

Technicalities​

They are alright. Separation is decent. Sound stage is average but with decent height. Zero easily wins here.

Bass​

Pretty flat but I'm surprised by the sub-bass rumble and texture. Mid-bass has good punch. Overall bass performance is better than the Zero.

Mids​

Lower mids are pretty thicc. Vocals don't sound distant. It is certainly better than the Zero in this regard, though I don't have anything to say for the upper mids because of how bright it sounds LUL.

Treble​

They sound pretty dry to me. To my ears there is a huge elevation in the 6k to 8k region, but nothing much after that? I had to swap the tips as I find the BB tips to accentuate the upper mids and highs even more.

Conclusion​

Very bright IEM. Want very bright? Get very bright. Don't like very bright? Get very bright anyway because very bright. You can find more products from Zhulinniao on Taobao

Introduction‎​

I was casually scrolling through Facebook one day and I saw a post from the ChiFi Audio group with the IEM named "Linglong". I thought to myself: "Huh. Does KZ, a Chinese brand not know that it is a racial slur used against Asian people (including myself)? That is amusing. " Eventually after my ADHD brain settled down I realized that it is a bullet-styled IEM, a design that I prefer. I then proceed to check on how much they cost at my local marketplace.

$8!?

I promptly made the purchase (impulsively) despite the fact that I don't listen to music due headaches I get thanks to ADHD, and decided to give the Ling Long a chance anyways. Boy was that a good decision.

*Professional* audio analysis​

yes

Bass​

Don't be intimidated by the bass from the graph, because it does not sound as 'in your face' as it looks. The sub-bass boost is most present in hip-hop tracks. If you are a bass-head these will likely not satisfy you due to the lack of mid-bass.

Mids​

Lower mids are slightly recessed but males vocal sounds great. The boost somewhere between the 1khz - 2khz region suits my preference and makes vocals and instruments sound lush.

Treble​

There is added treble to make it sound crispy - the smooth kind. Treble is perfect when paired with a neutral source. Female vocal sounds amazing. Symbal crashes sound sparkly enough. These are prone to sibilance and some tracks are harsh to my ears as I am extremely treble sensitive. SICKO MODE by Travis Scott absolutely destroyed my eardrums.

Technicalities​

Soundstage is the widest among the bullet-style iem I have tried, but lacks depth. Seperation is average. Detail retrieval is average, does not help by the dip in upper mids. Staging is average for $6, but poor at $15.

Conclusion​

If the KZ brand does not offend you then you should definitely try these out.

Tips to reduce Driver Flex/Pressure build-up​

• Wear these like how you would wear regular IEMs
• Use eartips that has less/poor seal
• Make sure your earholes are dry
• Open your mouth while inserting (it really helps)
• Drill a hole in the housing? :LUL:
