It is also 2 different shades of wood too.

I think there are 3 versions of 3DT from what I have seen: Blue, green and blue resin/wood.
Green is China exclusive (limited edition), while blue is available at some sites and the most common blue resin/wood is for international.

The green is pretty. Honestly they are all pretty. I just personally like fairly muted colors and designs. Black, some metallic colors, some darker solid colors, etc are my personal preference when wearing an IEM. Though it is nice to have a few pretty ones for the collection to look nice when I eventually get a display case.

I heard that the blue version was for Japan?
I’m not sure, I only saw blue version on Hifigo and Taobao: https://detail.tmall.com/item.htm?spm=a220m.1000858.1000725.2.57a7bdb1vR4ns7&id=628546007016&skuId=4701858053088&user_id=2072923149&cat_id=2&is_b=1&rn=61aae49b7559af7584b0885b73c38b82

Thanks @TkSilver for this review.
Could you provide examples of music genre that the 3DT handles well and some that it struggles at?
I’m tempted but it’s always difficult to know if it will hit right for my library.
Hotel California MTV Unplugged Version & Mozart: violin concerto no.4 in d major kv218 - allegro - 2L - Tidal mqa
Tried with Gustard X16 dac, Zen Can - all spread smile for me on the entire song with detail presentation and grand space, no upper mid sting
It is not really bad with any particular genre, but it might not be the sound you want with some.
There is a very sharp rise and rather high over all gain in the 1k-5k region. HBB brings this up in his review as his issue with the set and as an example he uses
Starting around 2:40 when Merry Clayton comes in and starts singing as a trouble area for him. There is a lot more energy in this area then some other IEMs and it can be a valid criticism for the presentation I happen to like the stronger gain in the region and it is a song I enjoy on this set.
If you want an example of the closing of the sound stage in busier sections of a track then
Starting around 2:08 as more and more gets layered on the sound stage gets smaller but the excellent layering and separation capabilities of the IEM keep everything from sounding congested.
I happen to like the tuning in general but some stand out tracks I really like
The force of the underlying thump is great and never feels like it is overriding the rest of the mix that you can get with some IEMs that just have Quantity over Quality
The bass guitar and the electric guitar sound amazing and the extra gain brings something special to the very special voice of Susan Vega in this track. This was a favorite on the Moondrop Variations and it has been elevated just that little bit extra on the 3DT for me.
Does it do Metal? Yes, yes it does
The speed in this track can bring a lot of sets to their knees… this is not my favorite track of theirs (I like Soul Decay more), but it is a great test track for just how fast an IEM can handle things.
The vocals from Tarja and Marco are just incredible
I can’t help too much with country since I don’t listen to enough of it but for folk music
I love the natural timbre of the acoustic guitar and the vocals of Robert Earl Keen, they combine to create a powerful story.
If you are thinking about getting the 3DT the biggest issues to be aware of is that the IEM is huge. Like really really big, so it won’t fit everyone. Also the cable is awful so if you get it I highly recommend having a 2 pin cable available to use instead of the stock one. (I am guessing the blue and green non wood versions also have awful cables, but I only know for sure the wood and resin one does).

Better than FH7, I don’t believe. If you praise him so much, does he manage his price? And these huge shells! I read that the soundstage is not good.
Ok I will probably order them when you say they are better than FH7.
“better” is a bad word. Things are “different”. I prefer the UM 3DT vs the FH7 especially for the metal genre.
I don’t think anyone is pressuring you to buy anything either. What we have done in this thread is discuss the 3DT. I think @TkSilver has done a nice job of describing his experience with it and that he enjoys it a lot for his preferences.

I would be a very bad person to compare the FH7 to the 3DT. I stopped at the FH3 since there is something in the Knowles BA used (I will reserve judgement on Sonion or Sony since riku says they may be different for me) that causes me discomfort in the upper harmonics. So there are many metal tracks I just can not listen to at all on them. Honestly part of what I wanted to find was an IEM that could handle the bass as well as the bery driver in the FH3 without that discomfort.

My take on these from when I had them a couple months back:
- Horrendous suction/airlock issues regardless of tips
- some of the most beautiful percussion reproduction going
- didn’t have the low end to back up its high end so sounded hollow or grating with a lot of rock, some Hendrix tracks unlistenable for example
- very good texture in low end though, no such thing as “a vague bass note”, you’re going to great variance between the start and end of the note, and hear the drum skin or bass string or whatever made them ripples
- gorgeous build
- awful stock cable
- timbre for days
- mids/female vocals nothing special
All according to my ears of course (and based on when a correct seal was found after way too much fiddling)
For my ears they were nowhere near an all-rounder due to bass amount. So combined with fit issues, a pass in spite of their select virtues.
DD is my favorite and I respect the design and company, so I had wanted these to work out better for me than they did.

Couldn’t hold off anymore so just ordered a set - intrigued by the triple DD configuration in these and looking forward to hear how they handle the metal in my library.

Your not worried about she’ll size ? I am curious when you get it how large it is. I had no problems with fit on the ISN 40 or the Dusk.
No, not worried - unless they don’t fit 
. It’s a chance I’ll have to take as I had no way of trying them first. Chunkiest IEMs I have at the moment are UPs (which are fine for me) so hoping they are similar to these 
.
Edit: @Resolution as you have both, when you have a moment could you give me a steer on how the shell sizes compare between the UP and 3DT?

Anyone can compare the UM 3DT with the ISN H40 and 7hz Timeless.
Expecially for progressive metal/rock.
Would the 3DT be an upgrade vs the others?
Thanks
The Up shells are (I believe) identical to the Thieaudio Oracle and Excalibur. Very comfy.
The 3DT shells are large and a bit wonky. Don’t even attempt them if you don’t have larger ears.
