The Sivga Nightingale Pro is a high-quality in-ear monitor (IEM) with a specialized planar magnetic driver design. The earbuds utilize a newly developed 14.5 mm multi-magnet structure with neodymium magnets, ensuring fast response and powerful dynamics.
The diaphragm is extremely thin: only 0.008 mm thick composite combined with a 0.006 mm aluminum ribbon guide, contributing to clear high frequencies and a wide frequency response up to 40 kHz.
The housing is made from CNC-milled aircraft-grade aluminum-magnesium alloy, combined with hand-polished solid wood fronts, offering both durability and a warm, artisanal appearance.
In terms of user-friendliness, the Nightingale Pro features a detachable cable (0.78 mm 2-pin) with a 1.2 m silver-plated oxygen-free copper conductor and a 4.4 mm balanced plug, offering flexibility for future cable upgrades.
With an impedance of 16 Ω and a sensitivity of approximately 100 dB, this IEM is relatively easy to drive: it works well with USB dongles, portable players, or desktop amplifiers.
The sound of the Nightingale Pro is often described as open, natural, and detailed: deep, controlled bass, expressive midrange, and refined, broad high frequencies.
For a perfect fit, Sivga provides multiple sizes of silicone eartips, allowing users to find the right fit, which is important for comfort and audio performance during longer listening sessions.
