Even when you have a number of TOTL IEMs, there are times when a product can surprise you, bringing a breath of fresh air to what seemed like a stale 12 months in the world of top IEMs. One of those moments happened for me at Can Jam London, with the Melodic Artification Eternitum. After failing to secure a sample at the show, I insisted and eventually managed to get one.
The unboxing experience is as good as it gets, a huge wooden box, with a display for the conditions inside thereof. Upon lifting the lid, the IEMs rise to the top, in a jewelery like fashion. Underneath, a removable tray holds the dedicated amp, while a third layer, on the bottom of the box holds the two carrying boxes. Exquisite presentation.
Everywhere you look, the attention to details is astonishing. From the shells construction to the logo pattern on the carrying case. The packaging deserves a video review of its own.
The dedicated amp requires some clarification: Eternitum is not a system IEM. It can be listened to independently of the amp. However, the provided amp introduces a slight bass shelf, even in the lowest bass setting, so it comes highly recommended. The built is equally good.
Moving on to the sound, Eternitum is a clean, blazing fast IEM, with a particular spatial presentation. The level of details is unlike anything I have heard, from the tiny textures in voices, to the guitars attack, everything is presented with a precision I did not think it’s possible. What is even more impressing, it does that without sounding artificial. It manages to integrate all these details into a tightly knitted musical weave. It’s like a portal has been opened, exposing a new level of clarity.
However, Eternitum is not just a one party trick IEM, but a lot more than that. The stage is something akin to my highly praised Camerton Binom ER – a massive spherical space, with you in the center, the music not seemingly coming from a fixed point, but simply living in that space, all around you.
The bass is one of the strongest I have heard, rivalling Duality. It is, in general dormant, but when the music calls for it, it errupts with a force that could not have been foreseen. The little bass switch on the amp does not seem to change the crossover frequency, but the amplitude of said bass.
The level of details in the mid bass is elevated, without however having a clear mid bass focus, or being overtly present, like in the other resolution monster, the Hex.
The mids are highly upper mids centered, with great energy, that could be too much for some, but that brings a vital force making music feel so alive. Lower mids could have benefited from a touch of warmth, but if I need to choose details vs warmth, I already have some warm IEMs, so Eternitum comes as a last piece of the jigsaw puzzle that is my IEMs collection.
Without going too much into details, as a full review is coming, I find the Eternitum one of the best products of 2026, ticking more of my boxes than the highly acclaimed Ibuki.
