Singaporean brand MMR is always talked about recently. Thummim, as their flagship product, has a high degree of topicality. Although MMR hasn't been established for long, this does not affect their understanding of the craftsmanship of making IEM and the tuning. Even if the price exceeds $4000, this does not prevent Thummim from being a cost-effective product. It is equipped with an Eletech Plato cable worth $999, and it has been tuned specifically for Thummim. I confirmed with Eric. A storage bag with collectible value and a full set of Acoustune ear tips (really difficult to buy in the United States). But Thummim is an oriented IEM. If you want a close and warm voice, then it is probably not for you. But if you like low frequency and high frequency, especially for symphony, chorus, and other big compilation music, then Thummim will really be the best choice in this price range.
the thummim is by far the most opinionated iem i have owned, but when you agree with it, it's pure magic. it delivers endless gobs of musicality, energy, and warmth that you can wrap yourself and get lost in for hours. they are bass heavy, but not in a way that overshadows any part of the frequency range. as other reviews have stated, it doesn't work well with every genre (definitely not my go to for ambient, for example), but even then i could never see myself giving them up, they're just too much fun
Having owned the Obravo Ra-C-Cu and Audeze's LCD-i4, I am not easily impressed by most IEMs.
I bought the MMR Thummim (thanks for the awesome service, Andrew!) and was blown away by the headphone-like presentation (I had only experienced this with the Ra-C-Cu in IEM format before);
The Thummim might easily be mistaken for being rather bass-heavy but they are great with pretty much any genre you can imagine- with the notable exception of classical. Still, the Thum is the most unique IEM I have had the pleasure of owning and is certainly a keeper long-term. 5/5
