Abstract
The SIVGA Nightingale PRO presents the music with sensible sound quite than a impartial, boring tone. I like the readability, the see-through transparency, the flicker, the treble air, and the crisp but natural-sounding transients, which resemble what I’m listening to in real-life musical performances.
Professionals

Very clear sounding throughout the frequency vary.
Wonderful treble extension, readability, and air.
Cons
I want the photographs had extra edge definition.
The higher treble could possibly be an excessive amount of for treble-sensitive folks.
F
I’ve been questioning after I would get to assessment one other SIVGA product once more, as I used to be impressed by the SIVGA Que UTG IEM I beforehand reviewed, and have been utilizing it ceaselessly for its sheer readability.
I’m now glad to have the chance to assessment one other SIVGA product: the SIVGA Nightingale PRO, the successor to the SIVGA Nightingale, which was launched two years in the past.
The Nightingale PRO guarantees quick, clear transients, in addition to prolonged frequency response, treble readability, and wonderful micro particulars, because of its use of recent planar drivers with an ultra-thin diaphragm and an aluminum ribbon conductor circuit.
I’ve been eagerly awaiting its arrival at my doorstep for assessment, and based mostly on my expertise with the SIVGA Que UTG, my expectations for the Nightingale PRO are fairly excessive.
Will the Nightingale PRO reside as much as my excessive expectations? And the way does it examine to different extremely regarded planar IEMs, such because the LETSHUOER S15 and the Hidiz MP145? Discover out in my assessment under.
Options
SIVGA has been very lively in driver innovation, and the driving force within the Nightingale PRO isn’t any exception.
The Nightingale PRO includes a newly designed planar driver with an ultra-thin composite diaphragm construction, paired with a freshly developed 0.008 mm composite diaphragm and a 0.006 mm aluminum ribbon conductor. It’s rated at 16Ω for impedance with an SPL of 107 dB/mW @1kHz.
The Nightingale PRO options aircraft-grade aluminum, magnesium shells created via a 5-axis CNC machine.
This aluminum-magnesium mixture, along with the 5-axis CNC machining, gives a strong but light-weight development, weighing solely 8.7 grams every, which is gentle for an all-metal IEM, in addition to optimizing airflow and minimizing undesirable resonance, which colours the sound.
The Nightingale PRO additionally includes a very efficient pressure-release system that forestalls stress buildup within the ear canal, which might trigger headache, nausea, and ear ache throughout strolling and working.
Design
I like the form and colorway of the Nightingale PRO, which mixes completely machined metallic elements with a picket faceplate cowl, mixing darkish and silver tones with brown wooden, suggesting a sophisticated design with a pure really feel.
Nightingale PRO includes a turbine-shaped metallic nozzle cowl with a small vent gap close to it, which serves because the stress aid. There may be one other vent gap close to the faceplate and the QDC type 2-pin connector.
The QDC connection is initially reverse-polarity in comparison with the favored 0.78mm 2-pin connection.
Fortuitously, the Nightingale PRO follows the polarity of the 0.78 mm 2-pin connector, which I measured myself on the cable utilizing a digital multimeter, making cable substitute a non-issue as a result of it wouldn’t reverse the sign part.
Inventory Cable
The Nightingale PRO features a very nice-looking, premium-feeling 8-core LITZ cable combining single-crystal copper and silver-plated single-crystal copper wires.
The metallic 4.4mm plug has a spring on its again that acts as a pressure aid for the wires, stopping early harm from cable bending. The cable separator and the nech cinch are made from metallic, whereas the 2-pin connectors are made from plastic and metallic.
Consolation & Isolation
I seen the Nightingale PRO nozzle is neither too lengthy nor too brief, which makes it match completely in my ears. Regardless of the medium measurement of the shells, they sit flush in my ears.
The 8.7 grams per shell, which is common, and the 6.6mm nozzle diameter, regardless of being on the bigger aspect, together with the inventory ear ideas, really feel very snug to me. I can put on it for a really very long time with out discomfort.
Isolation common and is similar as with all IEMs with a stress aid system; some sound will get in, however the music simply masks it at a average quantity.
Packaging & Equipment
The packaging is straightforward, environment friendly, and straightforward to open. The underside half has an extension that makes it straightforward for the fingers to seize and open the field.
The unassuming textured black field, which measures 146 x 142 x 58 mm, options SIVGA logos on the high and a few textual content on the backside.
Contained in the field are one pair of Nightingale PRO Earphones, one Actual Leather-based Case, two Pairs of S Ear Ideas, two Pairs of M Ear Ideas, two Pairs of L Ear Ideas, and one Consumer Handbook.
Sound Impressions
I did my commonplace 24-hour burn-in routine for IEM reviewing by letting it play constantly with a DAP at average quantity whereas checking in now and again.
I’ve concluded that the Nightingale PRO doesn’t want a protracted burn-in interval. Maybe a 2-hour burn-in would suffice, as I haven’t heard any adjustments in sound after that. I seen a really small enchancment in midrange readability and physique, and treble smoothness after the burn-in.
For the sources, I used my iBasso DC-Elite and the MUSE HiFi M6 Double DAC amplifiers, with my OnePlus 13 Android telephone and Sony DAP because the music transports. I additionally use the FiiO M15S DAP, utilizing both UAPP or Poweramp music participant Apps.
Among the many included ear ideas. I used the factory-installed black silicone ear ideas as a result of I discover them essentially the most open-sounding and supply the very best soundstaging. I used the inventory cable.
Measurements
My measurement reveals a superb left and proper channel matching, indicating a excessive stage of producing high quality. There’s a gentle, pure roll-off within the subbass, and the midbass will not be boosted, making the Nightingale PRO’s bass sound impartial.
Midrange output will not be recessed or dipped, and the pinna achieve at 2kHz is properly tuned, with solely 8 db of increase, making it excellent for good picture presence and non-shouty presentation.
There’s a noticeable increase at 8kHz, including a pleasant brilliance to the sound, and a lift above 10 kHz, which provides air and micro element readability to the sound.
Abstract
That mentioned, the Nightingale PRO presents a really sensible and clear sound that, when listened to with eyes open, makes the venue or live performance corridor really feel prefer it’s in your room, however when listened to with eyes closed, you might be transported to the venue or live performance corridor with a bit of stretch of the creativeness.
I’m a bit of hooked on listening to the Nightingale PRO, so I’ve dug into my outdated favourite songs in my library to listen to the way it presents them.
Once I was listening to “Don’t Begin Giving Up” by Mike Francis on the Reside in Manila Album. With eyes closed, I used to be transported to the live performance corridor, and I heard each nuance of the gang, the see-through transparency of the sound, and the ambiance, environment, and air.
The sheer transparency and readability of the sounds permit me to simply hear the minute vibrato of the voices that I don’t usually hear with lesser IEMs, particularly the feminine vocals.
Male vocals are rendered equally properly with a impartial, non-artificially thickened presentation or with out added heat.
Regardless of the gentle measured subbass rolloff, the Nightingale PRO delivers subbass when the observe calls for it.
The bass will not be anaemic; it’s energetic, quick, and has a really clear transient response; there’s completely no boominess, but the general bass will not be skinny, simply impartial.
SIVGA nailed it in the case of tuning the height in pinna achieve, which the Nightigale PRO has a really median peak of 8dB at 2kHz.
As I mentioned within the measurement part, it’s excellent, giving me good picture presence whereas avoiding higher midrange shoutiness, which might trigger listener fatigue. I additionally like how the treble is ethereal but non-fatiguing.
Coloration
The Nightingale PRO is subjectively a really pure and realistic-sounding IEM. It renders the sound with a lifelike presentation.
Particularly the cymbals and hi-hats, with a crisp chew and quick transients, making it sound very sensible, not like the seemingly pressured particulars and extension of most IEMs. When it comes to subjective realism and naturalness of the sound, Nightingale PRO is among the many greatest I’ve heard.
Though the Nightingale PRO has a sensible and pure sound, it’s not essentially the most objectively correct or impartial, as there’s an obvious increase within the higher treble on first pay attention; nonetheless, listeners shortly regulate to the increase, leaving a really clear sound on extended listening.
The rise within the treble doesn’t appear to introduce undesirable coloration however quite to be a welcome addition that makes the sound extra lifelike, as if it weren’t there.
Regardless of having superb sound readability, technical efficiency, and transparency, my total impression of the Nightingale PRO sound is that it’s a musically fulfilling sound expertise.
It permits the listener to benefit from the music quite than having an analytical or scientific sound presentation, the place the mind retains analyzing the sound as a substitute of letting the soul have its fill of musical bliss.
Moreover, I didn’t hear the difficulty plaguing planar IEMs up to now: a scarcity of subbass density in comparison with dynamic driver IEMs, as a consequence of planar drivers having a lighter, thinner diaphragm.
And in addition the planar timbre that many complained about, which colours the sound with dry textures and treble peakiness. The Nightingale PRO doesn’t have this situation.
Soundstage
The soundstage is big, open-sounding, pure, ethereal, and atmospheric, which helps loads in giving the Nightingale PRO its sensible and pure sound.
It’s large, deep, and excessive on the similar time, making for a natural-sounding soundscape, or no less than an optimized high-end stereo or surround-sound setup form of enveloping sound.
That mentioned, relying on the recording, the Nightingale PRO gives me with good imaging, the place the devices or vocals appear to emanate from their very own locations. I additionally hear a very good presence of the ambient sound throughout me.
Nonetheless, the imaging will not be essentially the most correct or technically the very best I’ve heard; I hear a barely subtle picture that lacks essentially the most definition within the edges, in comparison with the very best I’ve listened to on this regard.
The Nightingale PRO’s imaging efficiency will not be the very best, but it surely actually is above common, with good separation between the instrument and the layering, which is rendered properly.
I hear a powerful essential vocal presence, with the backup vocals and devices emanating from the again and being simply identifiable.
Dynamics
There may be by no means a boring second with the Nightingale PRO. It sounds energetic from subbass to the ultra-high frequencies. Even at decrease quantity, the Nightingale PRO sounds alive.
I additionally seen that Nightingale PRO can take plenty of energy with out distorting, compressing, or dropping composure. I attempted listening at greater volumes, and my listening to appears to be the one to surrender, not the Nightingale PRO.
