QoA Martini Assessment
Abstract
The hybrid QoA Martini is a well-balanced, finely tuned IEM that’s appropriate for crucial listening on account of its excessive technical capabilities.

QoA, or Queen of Audio, is a sister model of Kinera, recognized for its superbly designed and good-sounding IEMs, a few of which have been reviewed right here earlier than, together with the properly designed QoA Aviation, the fantastic-looking Thorking, and the lately launched Kinera NOTT Phantom.
Design and sound tuning idea impressed by the Martini Cocktail drink, with its sparkly appears to be like, and the cocktail’s steadiness of Campari, vermouth, and gin in a 3:5:2 ratio, the QoA group tuned the Martini earphones with a 3:5:2 bass-mid-treble steadiness.
In keeping with QoA, this tuning delivers satisfying lows, clear, current mids, and glowing highs—creating an immersive soundscape as nuanced and harmonious as the unique drink.
Can QoA ship these guarantees? Or how will Martini evaluate to different good-sounding IEMs akin to Softears Quantity S and LETSHUOER Mystic 8? Let’s discover out.
Options
The QoA Martini is a tribrid common in-ear monitor with 3 kinds of driver know-how.
Inside is a 10mm bone conduction driver for bass suggestions, a 6mm Liquid Diaphragm Dynamic Driver for the mid-bass, 2 Knowles full-range Balanced Armatures for the mids, and a couple of customized Balanced Armatures for the highs and ultra-highs.
Martini employs a 4-way crossover for its six specialised drivers and encompasses a stress reduction system that stops stress buildup within the ear canal, which might trigger nausea and complications.
It weighs 5.7 grams, has an impedance of 14Ω, and a sensitivity score of 105 dB/mW.
Design
The Martini options an attractive-looking 3D-printed shell, which is absolutely embedded with advantageous purple coloured steel flakes, and a faceplate with coarser purple steel flakes and Martini lettering.
The nozzle appears to be like like plastic and is 6.4mm in diameter, which is barely on the massive aspect, however nonetheless comfy with the included ear suggestions. There are three vent holes within the shell close to the 2-pin connector.
Inventory Cable
The QoA Martini encompasses a 1.2-meter premium 6N OCC copper cable, characterised by a four-strand, hand-braided Litz design with an general diameter of 1.8 mm, all encased in a sturdy brown PVC sheath.
It terminates in a gold-plated 4.4 mm mounted balanced plug and makes use of 0.78 mm 2-pin aluminum-alloy connectors.
Consolation & Isolation
Because of its ergonomic form, reasonable dimension, and light-weight weight, plus the efficient stress reduction system, the Martini may be very comfy to put on, even throughout lengthy listening classes, anytime, wherever, with none stress build-up.
Isolation is similar as any IEMs with a stress reduction system; some sound will get in, however they’re simply masked by the music being performed at a reasonable quantity stage.
Packaging & Equipment
The QoA Martini has a barely luxurious packaging that befits its worth; my unboxing impression may be very constructive.
It contains the Martini IEMs, a 6N OCC 0.78 mm 2-pin removable cable with 4.4 mm balanced plug, six pairs of silicone rubber ear suggestions, three pairs of AZLA Crystal ear suggestions, a Real Leather-based Storage Case, a cleansing fabric, and a consumer handbook.
The included real leather-based case has a pleasing odor, typical of any brand-new real leather-based product, and options magnets to maintain the door shut.
Sound Impressions
I did my normal 24-hour burn-in, however on account of a busy schedule, I left it burning in for 8 hours extra. I didn’t discover many modifications in sound after 8 hours of burn-in. An in a single day burn-in, achieved by enjoying music at a reasonable quantity, must be enough for the Martini.
For the sources, I used my iBasso DC-Elite, MUSE HiFi M5 Extremely DAC amplifiers, utilizing my Android telephone, OnePlus 13, because the music transport, and the FiiO M15S DAP, utilizing both UAPP or PowerAmp music participant App.
Of the three ear tip varieties included, I used the white suggestions, which resemble the favored Acoustune AET07 ear suggestions.
Measurements
My measurement reveals a wonderful left and proper channel matching, indicating a excessive stage of producing high quality. There’s a reasonable bass increase of 10 dB under 50Hz, reasonable as a result of 4 to 7 dB is taken into account impartial sounding.
Bass response slowly glides down in direction of the midrange at 500 Hz. I respect that the response has a mild glide somewhat than an abrupt tuck within the higher bass, as one of these bass response helps keep away from skinny be aware weight.
Not like different hybrid or tribrid units, which frequently exhibit a tuck-in response within the higher bass, this could trigger a skinny be aware weight sound.
There are inaudible glitches close to 180 Hz and 200 Hz, that are brought on by the bone conduction driver interacting with the shell and the ear suggestions.
A ten dB pinna achieve hump centered at 2.5 kHz is reasonable and mild sufficient to sound nice but by no means causes the devices and vocals to lose presence.
There’s a gentle hump centered at 8 kHz, which makes it look worse, as a result of it coincides with the measurement artifact peak of my measuring software. In precise listening, that peak is far milder; it doesn’t colour the sound an excessive amount of, as an alternative including a bit extra sparkle to the sound.
The higher treble above 10 kHz may be very prolonged, giving an phantasm that Martini has an infinite treble extension.
Abstract
The Martini boasts an virtually impartial, gentle V-shape sound signature, characterised by barely thick, but sparkly, ethereal, and energetic sound presentation, leading to a energetic, non-fatiguing, and musically communicative IEM.
Bass is energetic and punchy with quick decay, making for a clean-sounding bass. But, it’s able to producing an ominous rumble within the deep bass, which provides stress to the sound appropriately when wanted, and by no means slows down the music.
Midrange has a slight heat, but doesn’t lack presence and readability. Female and male vocals are offered equally with acceptable physique to the sound, devices are clear and detailed, with an correct instrument be aware weight.
Treble is sparkly, clear, and prolonged, with loads of element; the general sound is remarkably clear, with no veiling current. The Martini has a wonderful steadiness of heat, presence, and readability.
Coloration
Whereas Martini sounds very clear and virtually impartial, everyone knows that each one IEMs have coloration to their sound.
There is no such thing as a coloration when it comes to driver distortion, noise, or shoutiness in sound; as an alternative, Martini’s coloration is the gentle thickness within the higher bass, which might be as a result of 10mm bone conduction drivers, which provides musical magnificence to the sound somewhat than the destruction of sound.
Sparkly highs additionally rely as coloration, however much like the above, it doesn’t make the sound worse; as an alternative, it makes the sound extra pleasing and musically partaking.
Soundstage
Martini has a giant soundstage, because of its clear sound, tremendous prolonged highs, and deep bass. The form is spherical, and the texture is pure, like you’re listening in a bodily atmosphere.
Just some hours in the past, I used to be at a energetic occasion with buddies, and I needed to stand on the aspect of the room on account of fullness after overeating.
Fortunately, I had the Martini IEM with me, in addition to the Khadas Tea Professional BT DAC. I used to be transported from the acoustically useless personal room to golf equipment, outdoor, and live performance halls once I listened to this setup.
I used to be getting misplaced within the music. Sadly, I needed to get again to the true world as my buddies have been calling me. It was an eye-opening expertise, regardless that I’m an skilled listener. Martini shocked me with how nicely it communicated the music straight to my soul.
Imaging
Imaging is holographic; photos emanate from in every single place and usually are not bunched up in a slender airplane. There’s a retro chillwave music that I hearken to, the place an digital drum roll seems at my 10 o’clock, and a second later, the sound returns as an echo with results at 4 o’clock.
Middle imaging, particularly the principle vocals, is nicely outlined, with a definite place in entrance, that’s not in your face, however not too far both, simply barely out of attain. And different devices have good layering additional again from the principle vocals
Dynamics
Martini is energetic sounding when listening at low, medium, and excessive volumes. It’s straightforward to drive, even low-powered sources can drive it to a deafening stage, and it doesn’t endure from apparent dynamic compression with high-powered sources at loud volumes.
There’s this heat enthusiasm within the lows and liveliness within the highs, making the Martini sound enjoyable and by no means uninteresting, but refined for crucial listening. There’s by no means a uninteresting second with the Martini.
Martini can take plenty of energy from the supply and may get very loud, so my listening to can be the primary to surrender earlier than it begins to make noticeable distortion.
