The SIVGA Nightingale PRO is a well-built and beautifully finished pair of in-ear planar magnetic headphones that deliver a highly detailed, analytically focused sound. Their lean bass, forward mids, and energetic treble create a presentation that suits acoustic, jazz, and vocal-centric music but may feel thin and fatiguing for listeners who prefer a fuller, warmer, or more modern tuning. With excellent craftsmanship, strong technical performance, and a distinctive aesthetic, the Nightingale PRO stands out as a niche but capable option for detail-oriented listeners who value clarity and speed above all else.
I have previously received the SIVGA Phoenix Headphones and Robin (SVO21) Headphones and was impressed with the overall performance. One of the main characteristics of SIVGA earphones is the use of wood in their products, and the same is true for their latest launch, the SIVGA Nightingale PRO. Unlike my previous reviews, the Nightingale PRO are in-ear planar magnetic headphones.
The retail packaging for the Nightingale PRO includes a pair of Nightingale Pro earphones, a hard storage case, a detachable cable (4.4 mm balanced plug), two pairs of Ear Tips in different sizes, and a user manual.
The Nightingale PRO utilizes a proprietary planar magnetic driver system designed to manage sound production through magnetic fields rather than traditional dynamic coils. The driver features a substantial 14.5 mm planar magnetic driver, a newly developed composite diaphragm, and a multi-magnetic array consisting of high-performance neodymium magnets.
The aesthetic and structural design of the earphone housing combines natural materials with functional manufacturing processes. The outer faceplate is crafted from Zebrawood, while the earpieces are designed as in-ear monitors (IEMs) with a specific nozzle angle to fit the ear canal.
The Nightingale PRO includes a high-specification cable designed for audio signal transmission and durability. The cable is an 8-strand braid comprising 26 AWG Litz wires with a hybrid copper and silver-plated copper construction. The cable connects to the earphone housing via a standard 0.78 mm dual-pin interface and features a 4.4 mm balanced plug termination.
The build quality of the Nightingale PRO is solid overall, with the housing constructed from a composite material and securely attached wood faceplates. The included cable exhibits some memory and tends to retain kinks from storage, while the hard storage case is functional and attractive with its tan leather coating.
Comfort with the Nightingale PRO is acceptable but not exceptional. The compact size works well for those with smaller ears, but the fit is somewhat dependent on finding the right ear tip combination. Isolation is mediocre due to the shallow fit, and the lack of depth in the nozzle may require readjustment during extended listening sessions.
In terms of sound quality, the Nightingale PRO is not tuned to be a “fun” or overly musical IEM but prioritizes detail, clarity, and transparency. The bass region is lean but tightly controlled, the midrange is clear and detailed with a forward presentation, and the treble is elevated and energetic. The overall sound signature works well for specific acoustic genres but may not suit listeners who prefer a fuller, warmer tuning.
Overall, the SIVGA Nightingale PRO is a unique and technically proficient in-ear monitor that appeals to a specific taste. Its combination of planar driver performance, natural wood aesthetics, and solid build makes it a distinctive option for detail-oriented listeners who value clarity and speed in their audio experience.
