Jomo Audio Trinity Review

Back in February, I attended Canjam NYC to get the scoop on new headphones.  And the biggest in-ear show-stealer came in the form of the Jomo Audio Trinity. With dynamic, BA, and electrostatic drivers, this earphone constitutes a world-first and an indelible triumph for the Singaporean manufacturer.  But at $2799, is this juicy peach worth the squeeze?

Even in its retail packaging, the Jomo Audio Trinity appears big.  Within the large black box, you’ll find the earphones and cable, as well as two carrying case, a cleaning tool, a cable clip, 1/4” stereo and airline adapters, and six pairs of eartips.

The Trinity uses a 2-pin cable connection, opening up compatibility to hi-res third-party cabling options by Effect Audio and others.  However, the included 4 ft (1.2 m) cable still offers decent sound quality.  And, while it may seem a little thin, the lightweight does wonders for the Trinity’s comfort.

While the earphones’ housings might seem a little big, they wear quite easily once placed in my giant alien moose ears.  With minimal protrusion and a snug fit, they do a good job of blocking out office banter and surrounding distractions.  Sure, I kind of wish they were just a bit smaller, but that housing still seems fairly small when you consider the driver technology.

Inside each earpiece, the Trinity holds a single 8 mm dynamic driver, four Balanced Armature drivers, and two electrostatic drivers.  Together, the seven drivers offer four-way crossover, imparting a rich and highly-detailed sound.

Frequency Response:  20-80,000 Hz
Nominal Impedance:  30 ohms
Sound Pressure Level:  NA

Jomo is up front in clarifying that the upper limits of the Trinity’s frequency range borders on the theoretical.  That being said, the numbers promise a good deal of attention to high-end frequencies, so the Trinity should be no slouch in this area.  With an impedance at 30 ohms, the Trinity won’t need loads of power – but a good DAC is a must, and some amplification wouldn’t hurt.  Finally, the manufacturer doesn’t rate SPL.  However, volume seems adequate even when played directly from a low-output device like a computer or a smartphone.

Low End

Slightly subdued but incredibly lifelike, the low end on the Jomo Trinity sounds extremely satisfying.  There’s an organic quality to the sound here, never too colored or overpowered while handling everything with a characteristic accuracy.  Rock and electronic music sound as excited and energetic as they should, but without the over-reaching warmth of other, bassier earphones.  Bass impact still remains tight and pointed, though, coming through with a raw sense of depth and power that allows my hip-hop test tracks to shine with a grooving, thumping beat.


When it comes to the mids, you can really get a sense of how well those four BA drivers are being used.  Vocals sound intimate.  Individual syllables register sharp and contrasting, highlighting the diction of a rapper, or the emotion in a singer’s voice.  Complimenting this, instrumentation remains clear and clean, leaning just a little forward, to impart a rich midrange on the sound of the Trinity.

High End

I was half-expecting the high end on the Trinity to sound brighter.  But to my shock, it remains relatively tempered and even.  With plenty of detail, instrumentation and high-octave vocals still register as they should, but the sound never becomes too harsh.  This results in a fairly smooth high end that belies the detail lurking there.  I’ve never heard such a good high end at this price point before, though I’m very curious to stack it up against the Tia Fourte.


With depth and space aplenty, the Trinity adds an impressive sense of soundstage to any track.  Each note occupies its own space, leading to a resolving and illuminated sound that feels as realistic as it does intimate.

Other Observations

The Jomo Trinity comes with a standard copper cable, but would probably sound even better hooked up to a balanced cable from Effect Audio or ALO.  There’s a richness and fidelity here that needs to be taken advantage of, and at the very least a good DAC is a must.

No one part of the frequency range stands out.  As soon as I try to focus on something I like in the highs, something I like just as much appears in the lows, or the mids.  Overall, the sound remains impeccable, and each listening session proves more rewarding than the last.

If you want the very very best in in-ear headphones, the Jomo Audio Trinity should be near the top of your list.  The only earphone I can think of beating it – maybe – might be the 64 Audio Tia Fourte.  More expensive at $3599, this earphone has, up until now, been my go-to recommendation for detail and soundstage.  Now the Trinity threatens to steal the Fourte’s crown.

For fans who want more punch in the low end, skip this earphone and pick up the Empire Ears Legend-X at a slightly-more-affordable price ($2299).  Or you could consider the Noble Audio Khan, which offers a fast, powerful low end with some added soundstage (at $2399).

For more mid-high emphasis, I think the Fourte might actually be a smarter choice.

But if you’re in the market for the one earphone that can probably do everything you want…the Jomo Trinity looks like the game changer Audiophiles the world-over have been waiting for.

Final Analysis

With a $2799 price tag, the Jomo Audio Trinity ought to sound amazing.  But somehow it still manages to exceed my expectations every time I listen to it.  With its comfortable fit, impressive technology, and mesmerizing sound, there are minimal drawbacks to falling in love with this gem.  If you’re in the market for a religious experience as much as an earphone, the Jomo Trinity delivers the miracle you’ve been waiting for.
