The Nightingale Pro is a planar magnetic single driver IEM (in ear monitor) featuring a metal housing and wooden faceplate. Launch price was 295 USD.
The 14.5 mm proprietary planar magnetic driver features a multi-magnetic neodymium array, a structure designed to improve efficiency, dynamics, and transient response. The composite diaphragm is 8 microns thick (0.008 mm) with a 0.006 mm aluminum ribbon conductor.

BUILD, DESIGN AND COMFORT
The shells are CNC-machined aluminum-magnesium alloy and feature a Zebrawood faceplate that is both decorative and potentially acoustically relevant.
The shells are on the larger side, but they sit comfortably in my ear. I would not want them to be any larger, though. They do not protrude much.
The cable is an 8-strand braided 26 AWG Litz design combining single-crystal copper and silver-plated single-crystal copper. It is detachable via standard 0.78 mm 2-pin connectors, and terminates in a balanced 4.4 mm jack. It looks and feels very nice.
Also included is a brown real leather case with a zipper closure, excellent for carrying in a bag.

Outlaws by Bill Frisell
The sound is very detailed and spacious, with a natural warmth and great tonal balance. Percussion is snappy.
How Deep by John Scofield
The electric lead guitar has a very nice glowing warmth to it, and the overall presentation is snappy and detailed.
Impedans by Erlend Apneseth Trio
Excellent instrument separation. The electronic bass drum is wonderfully textured.
Sujet Tabou by Renaudin and Cahours
The soundstage is very open, percussion is fast and snappy, and the guitar timbre is excellent.
Sandermosen by Maridalen
Again the presentation is very spacious, and the imaging is impressive. The instruments are extremely well separated, with great timbre and a very nice balance against each other.
Spontaneous Compositorius by Thomas Agergard
The saxophone has warmth and texture. The bright percussion is clean and clear, without being overly sharp or piercing. The bass is well balanced with excellent detail.
Re-Melt by Tord Gustavsen Trio
The piano timbre is great, the percussion is fantastically snappy, tactile and fast, and there is a great sense of space and instrument separation.
Eye of the Day by Marta del Grandi
The snare drum is very tactile, the acoustic guitar detailed and nicely crisp, and the vocals are smooth as butter but with a rich sense of nuance.
Soft Stud by Black Belt Eagle Scout
The guitar riff has great texture and warmth. The vocals are smooth and delicate. The buildup is wonderful, with the bass entering gently.
Teardrop by Massive Attack
The bass is excellently balanced, with a combined sense of richness and tightness that is rare. The percussion is very snappy, and the vocals are smooth and delicate.
The Hidden Camera by Photek
The weight of the bass is very nicely balanced, both rich enough and tight and textured.
Limit to Your Love by James Blake
The vocals are great, excellently balanced, highly detailed and nuanced. The bass is more modest than expected and not handled as effortlessly as in the tracks above, though it must be said that this particular bass line is exceptionally challenging.
Murmurations by Vega Trails
The bass is extremely tight and detailed, but not overly rich. The imaging is great.
Desert Fish Finds Water by Karl Strømme
The presentation is extremely snappy with great instrument separation. The bass is not high in quantity but very high in quality, being extremely tight. The trumpet timbre is excellent.
Young Vivaldi by Modo Antiquo
The string timbre is excellent, somewhat bright but still smooth and detailed.
Summer 3 Vivaldi Recomposed by Max
Nice and clear, easy to follow the various instruments. Bright and upfront rather than dark and lush.
WRAPPING IT UP
Sound Signature
The Sivga Nightingale Pro has a neutral sound signature. There is no excessive bass or treble, and the midrange is very present. I find it very well balanced.
Treble
The treble is clear and crisp, very snappy without being sharp. It is the type of treble that is just there doing what it should: not overly bright, not dark.
Midrange
The midrange is very clean and wonderfully smooth, yet still with excellent detail. It’s a delight.
Bass
The bass has a nice warmth and richness without being excessive in any way. It is very tight and detailed.
Mostly, I personally find it perfectly balanced, but bassheads will not be satisfied.
Soundstage and Imaging
The soundstage is large and open, the imaging is excellent – the instrument separation is great.
Detail, Dynamics, and Timbre
The detail level is high across the frequency range. Dynamics are very good, with percussion being extremely snappy and fast, giving a very tactile experience.
The general timbre feels very natural to me. The bass is light in quantity but still rich and warm. The midrange is sweet and smooth, yet upfront and energetic. The treble feels just right and is precise. The Nightingale is neither overly lush nor too analytical.

7hz TIMELESS II vs SIVGA NIGHTINGALE PRO
The Timeless II, like by the Nightingale Pro, uses a 14.5 mm planar magnetic driver. It was launched in 2024 following the original and very popular 7Hz Timeless (2021). Typical price is 229 USD.
Like the Nightingale Pro, the Timeless II is an excellent planar magnetic IEM. They do however differ quite a lot in terms tuning. The Timeless II has significantly more bass and somewhat more treble, making its sound signature more V-shaped.
I have written a dedicated comparison review:

- Amazon: 7hz Timeless II
KIWI EARS ORCHESTRA II vs SIVGA NIGHTINGALE PRO
The Kiwi Ears Orchestra II is not a planar magnetic IEM, instead using 10 balanced armature drivers. It is an evolution of the Orchestra and Orchestra Lite, and was released in November 2025. It typically retails for 349 USD.
Despite the difference in driver configuration, the Orchestra II and Nightingale Pro share a very similar tuning and general sonic character. The Orchestra II has somewhat more bass than the Nightingale Pro, but less than the Timeless II mentioned above.

CONCLUSION
The Sivga Nightingale Pro is an excellent, neutrally tuned planar magnetic IEM. What stands out most is the sweet and nicely present mids and the polite but tight bass. I really like the tuning, and the technicalities are top notch.
The Nightingale Pro is easily among my favourite IEMs at this price point, and if you are looking for this type of tuning I can easily recommend it.
