Headphoneus Supremus
It's been a while but finally, I've been able to get something new to demo, and it's none other than the Jomo Audio Trinity Brass! Joseph Mou was very kind to send me a demo unit to try out - my interest in it was reignited when @Deezel177 and @Wyville mentioned that the Thummim reminds them of the Trinity with some differences in the peaks and dips - considering my ongoing wild affair with the Thummim, and the possibility of a custom glittered-up Trinity... well you get it
Now, to quickly cover my view on Thummim vs Trinity - ultimately they're both monitors that would fall in the How good your music could sound, adding a significant amount of coloration and bass and excitement to the mix, but I personally find that they also differ quite a lot - the Thummim has a more present and forward midrange (especially lower midrange), less forward lower treble, and a more pronounced treble extension. I find the Trinity to be more of a classic, fun-first V shape, while the Thummim is closer to a W.
Back to the Trinity though - I'm personally not a big fan of acrylic universals, but they do come in purple so Jomo have redeemed themselves there
they're super comfortable though, in that "semi custom" shape - I'm currently using them with some SS spinfits and they feel great in my ears.
It's worth noting that the Trinity is ridiculously hard to drive. I'm not a loud listener at all, but I'm reaching close to 90 on my LPGT on low gain, and almost maxing out my RME ADI 2 DAC as well. Underpowering them also pretty much eats away at the treble entirely, so I'd only really consider these if you have a decently powered DAP or even desktop amp to use them with.
Now, on sound - I've been finding myself absolutely loving my time with them... even though I really shouldn't be enjoying them on paper - I know that sounds weird but let me explain
Starting from the bottom up, the Trinity's bass is a classic Dynamic Driver in action - some heavy hits, some slow and pleasant decay (the Thummim is much faster and punchier in comparison), and excellent texture. I've come to quite enjoy a bold and present low end - I'd say in the case of the Trinity we're approaching basshead territory. It's certainly the bassiest IEM I have with me at the moment, as Trump would say - BY A LOT (not that much, it's a little bassier than the Thummim but I really wanted to say that)
The midrange and treble have the kind of tonal balance that normally does not resonate with me all that well - the lower midrange is somewhat sucked out, while the upper midrange is more present in comparison. I've been quite vocal lately about how unnatural that sounds to me, as I find it makes male vocals sound shouty and thin, and female vocals overly forward and bloated - the Trinity takes a different approach however - it places the lower midrange further back without actually boosting the upper midrange (or it might be a very gentle boost that doesn't sound as harsh to me as it does normally).
The treble also has the tonal balance in reverse of what I normally like - it has a more present lower treble (0 sibilance, but on some pop, rap etc you can get to levels that I'd consider slightly harsh) - it's nowhere near the peak of something like the Tia Fourte, but it's certainly more present than the IEMs I've been listening to most lately, i.e the Thummim, A18S and A12t. I think the lower treble peak is actually pretty well executed in the sense that it manages to steer clear of all vocals while boosting the perceived clarity of the monitor. In some harsher recordings you might end up finding it either a little overly intense, or just right depending on just how much headbanging you want to do.
The upper treble of the trinity is a little under-emphasized compared to what I'm used to - cymbals are present, they extend decently well - though they don't quite go into the highest registers - this aspect might have to do with how they are perceived as well, as they have a more neutral position compared to the rest of the treble and don't stand out quite as much as they do in a monitor like the A18S.
On technical ability, the Trinity does well - great dynamics and instrumental separation, pretty good detail for a V, reasonable staging depth and a sole weakness of relatively narrow staging - it doesn't feel congested or overly boxed in, but it doesn't stretch as far as I'd really like it to - reminds me a little of the Elysium in that respect.
TLDR and what I'm trying to explain as to the tonality of the Trinity:
When you factor in the V shaped signature of the Trinity along with the lower/upper mid ratio, you get a performance where female vocals are on the same plain as instruments (a more neutral positioning), and in certain tracks I'd go as far as saying they're slightly recessed - Mary J. Blige's Family Affair being one of those.
Male vocals have excellent body and texture, but sit further back in the performance. They aren't thin, or shouty, or unnatural - they do come across as "enveloped" within the instrumental performance though.
All this information becomes uselss when you feed the Trinity some metal or rock - the IEM absolutely slaughters it, transmitting emotion to the point that you find yourself fuming 15 minutes in. Would not recommend travelling with it as you might get yourself kicked out of a flight before it's even taken off for starting a fight.
