Cross posting here from another thread, but some impressions from Thummim:
Hello Friends, my turn for some Thummim action. I have had them now for a little less than two weeks and it's time to get some impressions out in the wild. First, I will say that these are easily the most unique IEMs I have ever seen and listened to. Visually, well, what the heck can you really say? They look like the Cybertruck of IEMs, built like tanks, controversial in shape, comfort that might be polarizing and they follow no prior trends. I like the design concept personally, but that may not be the case for everyone. Comfort works fine for me, getting a secure fit and no discomfort. I can feel an acute edge occasionally at the back of my ear if I put them in quickly and don't rotate or adjust them, but if I take two extra seconds to get a proper fit then it's a non-issue. I know they look like they might be torture devices, but they work fine for me. You should absolutely see if they work in your ears before making such an investment, though!
As for sound, these were tuned with pure guilty pleasure enjoyment with big, bold sound. I read something on MMR's website about an inconceivable soundscape and I have to say, that is accurate. I have never heard such a large stage in an IEM before, perhaps even some would find it TOO large where music is completely out of your head. I love it, but again it may not be for everyone. I have monitors that are more precise, easier to detect exactly where an instrument is within a more intimate stage, but these give a vast, concert hall feeling that is completely addictive to me. Imaging is still great, it's just that the instruments are in a concert hall instead of a studio.
Bass, to me, is tied as the star of the show with the treble. These have a deep, rumbly, analogue-type DD bass slam that I would put somewhere between the Tia Fourte and Legend X in quantity. It's punchy, impactful, and I think it will satisfy all but the most addicted bass heads. Mids have a lot of breathing room in the huge sound field, sound pretty natural while leaning toward warmth and texture rather than clear and airy. This is all in my opinion of course. I love the texture of vocals, the crunch of electric guitars and again it's just such a fun listen. It's not reference by any stretch of the imagination, but it's not hugely exaggerated in any one area either. It makes a lot of my other IEMs sound a little flat by comparison (Mason V3+, for example). But technical ability is still off the charts as far as detail retrieval goes, imaging & separation and stage as mentioned. It's definitely a W-shape, which works well for my musical tastes.
I saved the treble for last and I will preface this by saying I had completely given up on electrets...until now. Maybe it takes four of them in each side, maybe it takes a titanium cage for them to resonate in, I have no idea and don't really care: they sound incredible. Finally! They're crisp, clear, open, extended and have beautiful sparkle. I love the treble. Never harsh, never sharp, it would only offend the very most sensitive listeners, but it is perfect to my ears. There's a natural air to it without being splashy or cold. Well-done.
I'll provide some comparisons in the coming days, but for now I will just say that I love these. I would NEVER recommend someone go out and blind buy a pair of such expensive IEMs, especially with their shape that might not fit everyone's ears, but this has been an extremely exciting adventure that has paid off for me. Oh, and they come with the awesome Eletech Plato cable which I promptly stole and put on another IEM, replacing it with the Eletech Iliad I had for even more fun and bass debauchery.
Here are some photos, most of which I'm sure you've already seen from other posters:
