I see many mentions of various UIEM TOTLs here, Im actually currently tempting myself with these 3 IEMs :
1) Thummim (Based on the many great reviews but the company itself is kind of new and a little bit of enigma)
2) Erlkonig (It's VE and it screams luxury)
3) Noble Sultan (Incredible design aesthetics and they've been having a good track record)
Im leaning just a little more towards Thummim but im worried about the fit and if they are releasing anything better soon..?
Would appreciate you guy's opinion on this.
What kind of sound are you looking for - what specific sound characteristics are most important to you (lots of bass, extended treble, massive soundstage...etc.)
What music do you listen to?
The Erl is luxury all around - super refined sound, really clean presentation, loads of options etc etc (I'm not a huge fan personally as I found them a little boring but that's just me) - they have a massive fanbase, and rightfully so.
Raz and i are buds off head-fi, but calling the erlky "boring" counts as fighting words : ) Seriously though, in an effort to help you with your decision, i think it's important to clarify two things:
1) The erlky has an extremely balanced sound, with a relatively equal representation of all frequencies. For me, this is one of the characteristics that i look for when choosing an iem/headphone. That said, of course there are 4 different tunings that are easily accessible to you with the erlky. I generally switch between two of them myself, and these two tunings are easily as good as owning 2 separate iems, (for reference, the differences in sound on the erlky are far greater than say, when you swap apex modules on a 64a iem.) Each of the two settings I use have their own incredible tunings. My favorites are setting 1, which is a true bass monster, but with absolutely zero bass bleed and an uber-refined sound. Setting 2 tones down the bass a bit and is also ultra-refined, but is supremely balanced and still retains a truly powerful sound. Setting 2 on the erlky is my favorite tuning i've heard on an iem to date.
2) Raz and I have spoken extensively about the importance of knowing our sound preferences, and how that greatly shapes the kind of sound we all find personally pleasing. If your preference is for an "exaggerated sound," (with extreme highs, crazy huge sound-stage, and overall accentuated details,) I'd say the Thummim may work better for you than the erlky. I have not yet heard the thum myself, but I believe that it has a somehwat exaggerated tuning. In fact, this is precisely why I'm considering adding it as a partner iem to the erlky - I would love something that sounds "crazy" to complement the "natural realism" of the erlky.
I think it's a bit of a stretch to call the erlky "boring," but in this context of one specifically seeking a "crazy and extreme" tuning, I suppose I can see it. For somone considering purchasing the erlky, but unable to hear it first, "boring" may be a bit misleading (imho,) and I think it may be a confusing adjective to compute with all of the other descriptions out there about the erlky's sound.
I would say that the erlky has an extremely natural, realistic, and emotional sound; treble is the best i've heard to date (along with the bass, mids, organization of the soundstage, and overall level of detail.) But, the erlky doesn't have much exaggeration in its sound (except the bass on setting 1,) nor does it have an ethereal sound or any extreme sparkle in its treble; it sounds very natural, with amazing musicality and emotion.
Hopefully this gives you a better idea about the erlky, and how it is tuned vs something that's more "exaggerated," as I believe the Thum is (though again, I have yet to hear the thum myself.)
I doubt you can go wrong with any of the three iems you mentioned.
This is Raz's thread afterall, so I'll happily give him the last word. : )
