Ok guys, BGVP DM6 is finally in DA HAUS (M*THA F**KING FINALLY!). This will be my short (pfffhe he he) "initial impressions" post, plus some very important advice/suggestions/analysis from me.
First, let's start with some pictures of the "jewelry" :
(More in the spoiler):

TIPS AND SUGGESTIONS/RECOMMENDATIONS
- Improvised Gunk Guard
Now, I know many people asked what's the best way to put something on the nozzle to keep gunk/junk/earwax from entering the bores, and at the same time not to affect the sound/soundstage. This is my suggestion:
What I've used, is this thin, stretchy, spandex-y type of an woman socks material. It's kinda hard to describe, so here's an image:
You can simply cut some small pieces of it, place it on the back of the tip of your choice, and push the DM6 nozzle on top of everything:
That's it. It doesn't have ANY effect on the sound, and does the job. When you push the nozzle, it stretches, as you can see, and the mesh it's no longer "thicc", so again - perfect solution IMHO.

- MMCX and CABLES
Now, when it comes to the MMCX cables and their connectors, my experience was - initially, the NICEHCK Pure Copper cable was very stiff/hard to put on, and the left bud didn't even clicked. As others reported.
But, after swapping (very carefully) a few cables (The TinAudio T2's cable, which was clicking perfectly, the stock crappy grey SPC cable - piece of stiff crap, that almost broke, and then back to the NICEHCK 8 Core Pure Copper), the connectors "loosened up", and every cable from that point on was properly "clicking". No problem.
So, I currently have 0 problems with the connectors, on my NICECHK Pure Copper.

- The best TIPs
Yep, as of this moment, the tips that come with the Rock Zircons are still the best. Simply the best. I use mediums, and they isolate 100%. The problem is,you have to be REALLY careful, because they create complete "vacuum/seal", and if you push them too fast, you might pop your eardrums, because there are NO VENTS on the DM6, and there is no way to level the air-pressure.
In fact, you should all be VERY careful with the entire DM6, because in order for it to work properly, you need this kind of seal (mainly for the bass).
My tip here, is when you are inserting them in your ears (very gently), to move around your jaw, so that air can escape from the ear canal, while you are slowly pushing them in.
BUT IF creating such tight air-pressure seal is a NO-GO for you, the DM6 might not be for you. My friend for example doesn't even want to make a proper seal, and complains that the bass is very light and thin. Well, it's balanced armature, duuh. There is no dynamic to "move air". For me, when the seal is perfect, the DM6es are TOO BASS-y even. Damage level bass hits, even more depending on your source (more on that later).

INITIAL SOUND IMPRESSIONS
This IEM is literally magical! I haven't heard my music in such a way (for good or bad, more on that later). I will give you a couple of very brief examples:
(IMPRESSION DONE WITH THE AXON 7 mini, + the NICECHK 8 core Pure Copper Cable + Stock Music App in "SuperHiFi" mode, CD-rip FLACs + Couple of HiRes Tracks and some crappy mp3s)
As a start, no IEM that I've heard in my life ever achieved what the DM6 is doing, but keep in mind that I have tried/own the "cheap stuff", like the TinAudio T2, BGVP DM5, **** 4in1, the TRN Vhorrible80, and other stuff that are several levels below these, like simple single dynamics like the Einsear T2, Rock Zircons, and stock crappy phone IEMs/Earbuds (but those shouldn't even be mentioned in the same sentence with the DM6, and I understand why now): So, here it goes:
- The Instrument-separation/clarity/smoothness/detail/sound-stage/layering/imaging:
I'm blown away. the depth, the layering, the PRESENTATION, the location of the location of every instrument/voice... I basically didn't even knew what these things meant for an IEM, until now.
Vocals - Words cannot describe what the vocal experience is. But I will try. Vocals are smooth, distinguished. I was never able to hear the "lyrics" so clearly before. I'm not a native English speaker, so most of the time, I wasn't even sure what was sang, without checking lyrics (goes to show you on what low-fi crap I've been listening to my favorite thing in this life(music) my entire life, be it my crappy 2.1 speakers, my "plastic Philips HiFi system", , and pretty much everything else.) This is "experience". Not just listening to your music, but "experiencing it".
On duets for example, you can clearly distinguish both performers voices, overlapping, but clearly separated. And I mean CLEARLY. I've NEVER experienced music like that. Not to mention other voices mixed in the background, or other similar sounds/effects. THEY ALL COME OUT VERY CLEAR, but NOT shouting, up front, or in a weird place, they are exactly where they should be on the "depth" axis of the stage (layering) of the mix, it's like you're there, and you are hearing it in front of you with your ears in a environment.
That 3D holographic experience people were talking about? Yeah, it's real. I get it now. This is much bigger than the "hearing details you never heard before". This is whole different level. It's more like - "You-Haven't-Heard-It-THAT-Way-Before". I got the HDYNHB with the T2's when I initially got them, and thought things can't get better than this... (silly, poor me). In comparison though, it's like from Earth to the Moon.
- - -
BUT! There is a huge problem, and that's SIBILANCE. This is the most "shshshs" sibilant IEM I've ever put in my ears. Completely kills it for me. The problem are the "peaks" at 6-8kHz, that I tried to compare/simulate, from the measurements done by HBB and Crinacle. My EqualizerAPO simulations (that almost nobody bothered to check out, because you were all assuming automatically they are completely wrong), are actually very close to accurate to what I'm hearing, and sadly it's actually the simulation based on the Crinacle's graph that is closer (without the bump after the cavity at 10kHz), which I thought It sounded too much, and I assumed that I did something wrong (when technically I shouldn't because Crin's graph simulation should be the most accurate), but apparently, crinacle's simulation is the closest to what I'm actually hearing. You can check them out of you want, and if you prefer words than hearing for yourselves, there is only one way to describe - it's painful. You can't even crank the volume 2 notches before the middle, before it goes murderous on my ears.
The most painful songs are my usual:
Billy Idol - Rebel Yell (in the beginning when he starts singing, and the "S"es are overlapping;
and
Spud-u-Like by Barklay James Harvest. Those too are borderline unlistenable to me with the DM6. And that's on the neutral (best-sounding) Axon 7 mini, using the NICEHCK 8 Core Pure Copper Cable.
With the default gray SPC cable, or got forbid on my Axon 7 WITH that cable? That's just death. 100% unlistenable.
Now, I do have VERY sensitive ears, so keep that in mind. The shape of my ear canal might create a very bad resonance at these peaks, so It might be person-specific (but still, it's just too much). My friend for example doesn't hear it as bad as me, but he doesn't even make proper seal with the DM6 on purpose (too afraid of the air-pressure), so I can't take his assessment as something definitive.
The harmonics of percussive instruments like most drums (and bass kicks) sound EXTREMELY sibilant as well, because their harmonics hit exactly at these areas around the 6-8kHz, where the "SHSHSHS" sibilance happens. It's very uncomfortable, and also weird sounding.
As reported by many, the Cymbals also sound messed up. Their "heads" (fundamental hit) is very quiet, while the extension/decay/splash is VERY loud, making them sound just... kinda wrong. There are some songs that I know very well, where the cymbals/high-hats doesn't even sound like cymbals/high-hats on the DM6...
I feel really bad that the DM6es have these problems, when everything else is soo good about them. But, I will put them through at least 100 hours of "burn-in" (even though I don't believe in it as of this moment), that will tell me if these things improve. And I will be 100% honest as always. Just for the record, they already had ~ around 15 hours of listening time, and pretty much nothing has changed. Perhaps "very slightly" less sibilance, but that could just be in my head (or my ears adapted a litle bit - most likely that), but I can't say for sure, so... Yeah, I will discuss it in the full review.
That's it for now, as far as initial sound impressions go. I am trying to keep this brief, so not including specific samples, or going through describing the rest of the spectrum using different music. I will make final assessment after at least 200 hours, and the full review will include those, as well as everything else.

THE KINKS AND THE QUIRKS
- THE SENSITIVITY
The DM6's are extremely sensitive and SOURCE DEPENDENT! If you don't have a good source, or your source has ANY kind or coloration (or high internal impedance, like the Zishan DSD and Hiby R6, based on what I've heard about these too), you are NOT gonna have a good/optimal time (sucks for me) with them. You might actually hate them.
For example:
NOISE - The DM6'ses pick up ANY noise that happens in a circuit, or leaks into the DAC/AMP as an EMI interference. Things like wifi. This IEM though is on a whole different level.
My Axon 7 has some sort of IEM shielding problem in particular. I can LITERALLY HEAR COIL WHINE (my friend was well, where were What-ing the whole time), from simply scrolling, sliding my finger on the screen of the phone. That was a What moment. Both me, my fiend, my mother and so on could hear it. That just some next level **** (and a huge f*ckup on ZTE's part with the big Axon 7, because the Mini doesn't have that problem, neither do other phones I've tested, like the Galaxy S7 Edge and regular Galaxy S7).
Here's an audio sample, recorded from the DM6 just plugged in directly into my on-board sound card on my PC as an example, and (worst case scenario) (Motherboard is the GIGABYTE z97 G1 Sniper).
01 - BGVP DM6 - My Onboard Is Too Loud For You (Part. 1)
This is with sound completely muted, and the IEMs just plugged in. As you can see, that's just un-listenable/un-workable. And that MB has a "fancy" gold-plated EMI shield on top of the DAC (yeah, it totally works.../s) as well... For those that were wondering what's it like using sensitive IEMs on onboard sound solutions. there you go.
- - -
- THE IMPEDANCE
This is the DM6's greatest problem with most gear. 20ohms is in the middle of nowhere, so some devices will be running it in "higher impedance" mode, which is at the 32ohm step. This creates a HUGE problem with the DM6, not just when it comes to the noise I've mentioned above, but also it completely changes the frequency response.
The more colored the source, the worst results you are gonna get. Some sort of adapter is a MUST (to take care of the noise mostly). The Ideal would be 12ohm, but I haven't seen such an adapter anywhere. I might have to calculate and make my own. I have ordered the 20ohm impedance one from penon, and I will report the changes once I have it.
As for me, my Axon 7 SOUNDS LIKE F*CKING CRAP with the DM6. The sound is changed to a point that it's simply terrible. The SuperHiFi setting, that usually works like you are switching from low-to-high gain, does the EXACT opposite of what it should be doing. Sound gets quieter than normal HiFi, the dynamics are completely dead, bass is extremely boosted, as well as the worse peaks in the treble, making the soundstage extremely narrow (but deep), and tonality shifts greatly.
Yeah, my soul is crushed, because the DM6es simply do not work with the Axon 7 and it's colored DAC/AMP (AK4490). I've posted what the "coloration" looked like before, but here it is again.
The DM6 is very warm sounding IEM already, and ANY additional warmth added completely kills it's sound quality and intended signature. It's like listening to a very crappy cheap earbud, which sadly is exactly what it sounds like on my Axon 7. The regular HiFi setting is much better, but still really bad.
Heck, even the Galaxy S7 edge I borrowed sounded MUCH better, something I would'v never thought I'd say, although because of the crappy DAC/AMP in the S7 edge, the dynamics were very low (because of the crappy crosswalk), causing imaging and soundstage to suffer greatly. Yeah, it might sound better (as a signature), but it also sounds gust like a regular cheap IEM on the S7. Nothing like the Axon 7 mini, which just makes it SING.
That said, if you have a phone/dongle with bad crosstalk (most of them), you are not gonna hear what the capabilities of the DM6 are. Sad, but true. No accurate imaging, no deep and wide holographic-like sounds stage, nothing.
- - -
All of that said, the Axon 7 Mini actually sounded fantastic (Just to clarify again, all impressions you've read were done with it, because it simply worked the best with the DM6). It has the newer 4961 DAC/ADC, and it's very flat and neutral sounding phone (or cold/analytical). ONLY on this device, I can hear what the DM6 can do, and how they should sound like. There is no shift in tonality like with the other phones, and it simply sounds great, and even better on the SuperHiFi setting, which worked exactly as intended/should (High Gain with more dynamics).
I will edit this post and I will add some comparison recordings from all phones, just so you can all see what kind of difference it makes, and it's astronomical. Same with cables.
- - -
AND SPEAKING OF CABLES, yeah, they make a difference like a mofo. EVEN my mother noticed it. I've initially tried them with the TinAudio T2's silver-plated stock cable (much better then the stock grey one btw). It's pretty much exactly what I was describing/speculating in the graphs here. EXACTLY.
Test song was "Alphaville - Sounds Like a Melody". The synth at the beginning always tells of tonality/pitch shift, so that's my main song for that. Sounds the most natural (close to reality) with the Pure copper cable, and completely out of wack with silver-plated. That cable definitely helps taming down the highs as well, to a point that I think affects the already problematic cymbals too much, making their problem even bigger. But, it corrects the sibilance in the 6-8kHz (not greatly, but noticeably), so... YOU JUST CAN'T HAVE IT LIKE YOU WANT IT DAMMIT!...
As for the stock (grey) cable, it should be purged from the face of the Earth. It does something completely weird to the sound. Like, literally bringing up the WORST in the DM6. Increased bass, and even sharper peaks. It should NEVER be used, unless as a correction to a specific "source", or for very specific needs/taste. It's a downright crime that BGVP includes it with the DM6. Many people will hate the DM6 with that cable, it's kinda like BGVP are shooting themselves in the feet.
- - - - - - -
So yeah, those are my "brief" initial impressions with the DM6. I really hope they "improve" with more time passing/listening. But as of now, with MY source (Axon 7), I can't enjoy them at all. Will update when I get the impedance adapter. And yeah, the conclusion would be - a better (cold/neutral/analytical) source is simply a must.
- - - - - - -
As an extra thought, considering everything said so far, I can't help but wonder how much the test rigs that @crinacle and @Hawaiibadboy use affect the sound, and THUS, the result on the graphs. Not sure about crin, but the DA IMM-6 should definitely graph completely differently on a different devices, considering how sensitive it and reactive to different DAC/AMPs the DM6 is. The "approximated differences" between the test rigs that Crin provided here in the thread (which unfortunately he deleted because of some people acting weird, when I asked them not to do it) might not be telling the whole story... So yeah. If we could measure these differences somehow it would be great. With the IMM-6, perhaps attaching an impedance adapter (that has 2 poles ofc) would show differences (since the source is the wathever DAC/AMP that's inside the iPad)? I would really liked to test these things myself. The problem is, you can't buy the IMM-6 anywhere anymore, especially where I live....
Anyway, thanks for reading.
yup the DM6 really brings out the details of the song, don’t really have a problem with the treble, maybe my ear canal dampens the sibilance effect? lol
the DM6 are really sensitive, it hisses like mad on my Nintendo Switch
