Dude, where is your review of this IEM
Trae
500+ Head-Fier
Been giving the Dynaquattros a good listen over the past few days, and overall I like what I'm hearing.
The bass + pr drivers work really well together and give you a deep and well textured bass. It can also take a good boost with EQ to bring out some more slam in the sub-bass frequencies without distortion. Very clean, tight and dynamic bass performance out of this combo.
The midrange DD does its job very well. Always loved DD mids and I think they nailed it with this one. Warm, musical, detailed and natural sounding. It's bringing out some details that are more subdued on other sets, and overall it gives a pretty balanced presentation of the mids.
The treble DD is the reason why I bought these as I've never seen an all metal diaphragm be used in an IEM before, much less in a 3+1 DD configuration, but I'll say that my preconceptions were wrong. I was thinking that with a metal diaphragm that you'd get a really bright, sharp, extremely sensitive sound that picks up on every detail, but it's actually really smooth, tight, and clear sounding. It's not as airy as I would like, but I still really like how it does the treble. While some of the air is toned down, it makes it a little easier to distinguish some sounds in the treble that would've been subdued by a more airy set. I think it's a fair tradeoff and again it sounds pretty balanced to me.
Soundstage is an interesting one too, and I think it has to do with the subdued airiness. You get a stage where you know exactly how big it is, very well defined and very dynamic in size depending on what songs you're listening to. As a result, imaging is pretty concise and satisfying. As a soundstage nut, I like the quattro's.
These are a little hard to drive, so you'll need some power to wake these things up. So, don't let the low impedance and high-ish sensitivity specs fool you. I recommend using the 4.4mm cable as amps usually deliver more voltage with balanced outputs - something that'll definitely help with these.
The FR curve looks pretty Harman-ish to me with a beefier low-end and a dip at around 6kHz. If you like something like the Crinacle target curve, then the dip at around 12kHz is substancially larger and puts into focus why people are talking about the lack of air on this set. I'm not much of a Harman fan, so I did an Autoeq to Crinacle's target curve while leaving 20-300Hz alone. I don't really hear the 8kHz peak, and most of the time that's just resonance that is created by the IEC-711 coupler so I tend to ignore that peak in measurements.
Using EQ on these was a bit of a challenge at first because they don't respond too great due to what I believe stems from their driveability. These require a larger adjustment in dB to get the desired effect than what the graphs tell you. When it comes to EQ, bringing up the treble helps out a bunch with this set. After doing an auto-eq to crinacle's target from 300Hz-15kHz, I turned off the 8kHz adjustment for the aforementioned reason and then added a 3dB high-shelf qfactor 1.0 from 10kHz onwards. This really helped with bringing some presence and sparkle back into the treble.
For the bassheads out there, these can take a hefty boost in the sub-bass frequencies 20-80Hz and blend very nicely without sacrificing texture. But I have to emphasize that you might input +6dB, but what the graphs say and what your ears are hearing/feeling might not match up. This set is somewhat insensitive to EQ, but forturnately the FR curve is actually very smooth and straightforward. Just a couple of dips in two spots and a bit of a hill at 2kHz when conforming to the Crinacle target, so that made adjustements pretty straightforward. I just had to add or take away an extra 3-ish dB to compensate. For example, bumping the sub-bass by 5dB didn't sound like 5dB to my ears, and bumping it up by another 3dB to compensate did the trick. This might just be a unique issue on my end (S24U + Wavelet, Topping G5 4.4mm), but I thought I'd throw it in here for the tinkerers out there.
One thing that I observe when researching IEMs is how consistently do they measure across different samples, and based off of the squig measurements from various reviewers, these measure exceptionally consistently. All of the peaks and dips are in the same spots, and variances between sets are minor, so that says a lot about the QC on these sets. It also gives me more confidence in EQ because they measure so consistently.
Comfort is very nice on these too despite their larger size. They nailed the ergonomics at least for my ears.
This set sacrifices slightly on technicalities in exchange for more musicality and smoothness, and I think it's a very fair tradeoff. The best IEMs are the ones you enjoy listening to, and I really enjoy the sound these put out. They do a lot of things right, and EQ helps cover some of the shortcomings in tonality for me.

I listened to er4xr, er2xr and er2se. And i kept the er2se. It has DD. Er2xr somewhat had flabby bass and er4xr sounded drier. Er2se wasn’t dry in my perspective. I love its vocal as it was never harsh.
Dynaquattro sounds natural to me. No harshness. Just its male vocal seems like the singer is somewhat in the back side. I also now love my dita PM with my lg v60 combo, as male+female vocal is in forward and the mids is very crystal clear sounding.

Thanks brother. I just captured it with my x100 pro, added filter and cropped it.
Classy man!!
Tried the DAP a few days ago, but it was having a noise issue at that time, so couldn't give it a proper try. Great Power IG , looks dopeExcelent combination

Does anyone have Dynaquattro and also Aful performer 5 + 2 that could give a basic comparison
