I always regret that I didnt buy Believe before it became hard to be found in Aliexpress. It must be a good addition to your list.
Just out of curiousity, the order of IEMs in your signature is the order you prefer? or rank of performance?
You may find some classified deal on headfi👍
The orders on my signature is basically preferred order, some sticks together by brands. If rank of performance descending order, Tri Starsea will be far behind, but regardless of technicalities, I found it is the best laid back tuned IEMs among all.

For IEM/cans in spoiler, it’s just random sorting by brands.

Believe arrived.
Wow! As expected from Moondrop Aria, it is on similar vector, fast and rich, harmonious. Tempted to remove stock fabric acoustic filter..Still feel bass response is interfered.
A+ IEM for sure.

Congrats, those dampers occlude a lot of the top end though, undamped Believes were way too raw without something in there to take the edge off!
(and I did think bass dynamics improved a bit with foam dampers, just ended up going back to the original tuning as there's something very unforced and natural about it).
My mod below fwiw.
It's winter here, so time to give the Believe an anti-condensation mod. I was really hoping that having the damper on top of the dust guard would fix the issue of moisture blocking the sound, but this country is just too cold and wet, so if I want to use them outside without random volume losses some reconfiguration is required.

Long term I’d need a replacement for the original dampers anyway as they're going to lose transparency over time, and replacements aren’t included.

4.7mm dust guards and expanded cotton tuning dampers in the links below if anyone’s got the same problem (and wants to avoid channel imbalance issues from DIY foam), I use one of each (densest on top) to get a slightly more bass balanced, warmed up tuning than the original, with what sounds like a modest boost to note weight and clarity, especially at the bottom end. Separation seems slightly improved as well, but that could just be wishful thinking as it was pretty damn good already.

Update: Now that kbear have started stocking them as accessories, I've since switched back to Believe dampers without the dust guards, as the moisture only gets trapped between the damper and dust guard, not in the damper if mounted by itself.

ah.. great to know. You already tried!
Thanks for the note, I'd keep the filter attached :beerchug:

Actually since I noticed I had bunch of dumpers I decided to remove the stock one, it had 2 layers of dumper, one layer of fabric(paper-tape-like) filter and, another very congested small and conjested iron dumper, I basically find those iron with small outlets unjustifiable for acoustic tuning, so I removed.

OK, trebles got bit boost, but as the nature of pure-beryllium (light thin and elastic), treble boost doesn’t bother my ear, not like those BA or CNT dynamic driver’s screams. bass floor is lowered with more “direct raw sound”. I feel I need a bit more bass, so I may play with some tips/cables/dumpers.

[update]
added moondrop Starfield dumper filter.
Slightly better and cleaner than original, bass still sounds foggy 🌫.

will switch dump filter to find a better match.

Moondrop blessing2 filter:
Yes, only a slightest treble tame + bass floor raise, by only tiny bit. I will settle with this dumper👍
BBC6FED7-3258-435F-A02B-5C9498DB6524.jpeg


Final settlement: XELASTEC L & raw nozzle
Tried various tips, foams, final E, spiral dots, spinfits, UM, bass boost, all sort of tips and concluded for LCP & pure beryllium, AZLA xelastec works the best in taking maximum benefit of those drivers. The bass is uninterrupted, yet slightly lacking the quantity to my liking but I can live with this level of KBEar Lark level of almost flat bass.

Guitar picking and bass slapping is one of the best sounding on Believe, “elastic “ is an appropriate word I can think of , it bounced well with speed and punch, which BA drivers has the speed but no punch, other dynamic drivers has the punch but it blows slow. I found LCP drivers such as Moondrop Aria is more leaning toward CNT side, and Believe’s pure-Beryllium is toward BA side of tonality, means pure-beryllium has higher resolution and speed. Not huge but distinguishable one.

@WendyLi One thing that amazed me is that KB Ear uses genuine leather (not faux leather) for Believe's case. For $170 USD IEM? wow!
I've purchased quite a few of high-end IEMs, most of them just use faux leather or even flammable cheap polyester...except qdc and this Believe.

The touch of the genuine leather case is just astonishing, it's soft and intimate, feels like a product of Hermes. Great job KBEar! Hope you add those case to TRI product as well.

Craftsmanship. Touch of real aesthetics.


Another genuine leather, but it’s too expensive.

Curious how the sound from Believe would position in your signature :) haha. Hope you enjoy the new entry!
I pulled the trigger for Thieaudio Monarch, and I am expecting to receive them by this Friday. You comparison between MEST and Monarch helped me a lot actually.

I'm carefully examining now, after a while of DUNU SA6 which arrived on the same day with Believe, I have spent more time with Believe.

Currently, it is A+, somewhere between Dusk / SA6 / Blessing2 / Starsea.
Believe is inevitably the highest-ranked single Dynamic Driver IEM for sure. But I do note there are huge spikes for "raw outlet".

That's what I did to my pair of believe and am super happy with both bass and treble.
Just got rid of stock material on top of grill and put small micropore piece
