Sivga has introduced its newest in-ear monitor, the Nightingale Pro — a follow-up to the original Nightingale released back in 2023. This version keeps the familiar mix of metal housings and wood accents that Sivga is known for, but adds a newly developed planar magnetic driver meant to deliver a more open and controlled presentation. The Nightingale Pro sells for $269 and is already available through Amazon and other retailers.

This release also comes just weeks after we reviewed the Sivga Peng headphones here at HomeTheaterReview and awarded them Editor’s Choice, so the timing naturally puts some extra attention on what Sivga is doing across its lineup.

The big change with the Nightingale Pro is its updated planar magnetic system. Sivga designed a new multi-magnet structure that uses high-efficiency neodymium magnets, replacing the previous generation’s driver layout. On paper, this should give the diaphragm more even control and faster response, which can be helpful when you’re working with compact housings like these.

The diaphragm itself is extremely thin — 0.008mm for the composite base and 0.006mm for the aluminum ribbon conductor. Reducing the mass allows the driver to move more freely, which can support cleaner highs, faster transients, and a broader frequency range. Sivga lists the Nightingale Pro at 20Hz to 40kHz, a spec you usually see with planar designs even in higher price brackets.

Across the materials provided, Sivga repeatedly describes the sound as “natural” and “open.” Setting the marketing aside, what they’re essentially trying to achieve is a presentation where details come through clearly and the soundstage feels less confined than what you typically get from many dynamic-driver IEMs. Whether a listener experiences that difference will depend heavily on their own ears, music preferences, and the source they use.

The housings of the Nightingale Pro are CNC-machined from an aluminum-magnesium alloy — the same type of material often used in aviation-grade components. Using a multi-axis CNC process helps ensure each shell is shaped consistently and can also help reduce unwanted resonance.

The outer faceplates are made from hand-polished solid wood, which continues the aesthetic Sivga uses across many of its headphones. It’s mostly a stylistic choice, but it does give the IEMs a slightly warmer, more handcrafted look compared to fully metal designs.

Each pair weighs 27g without the cable, which puts it in line with other metal-housed IEMs. The included cable is a 1.2m silver-plated oxygen-free copper design that attaches with standard 0.78mm 2-pin connectors, so swapping cables later on is an option for anyone who prefers a different termination or material.

Sivga includes several sets of silicone ear tips to help users find the right fit. Like with any IEM, comfort will depend on ear shape and tip size, but Sivga says the Pro was shaped with longer listening in mind.

One practical aspect of the Nightingale Pro is its low impedance (16 ohms) and moderate sensitivity (100dB ±3dB). This combination means the IEMs don’t need a powerful source to reach full volume. Whether you’re using a dongle DAC with a smartphone, a portable audio player, or a desktop amp, the Nightingale Pro should behave predictably without demanding extra power.

This makes the model a potential option for listeners who want to try planar magnetic IEMs without investing in more specialized gear.

Technical Specifications:

The Nightingale Pro is priced at $269 in the US and £269 in the UK. It sits above the original Nightingale, which remains available at $229. The two models give buyers a choice between the earlier design and Sivga’s latest driver and housing updates.

The Nightingale Pro enters a crowded space where a lot of brands are exploring planar technology in compact IEM designs. Sivga’s angle here is to combine its updated driver work with the familiar metal-and-wood aesthetic that runs through much of its lineup.

We’ll have a clearer picture of how the Nightingale Pro behaves once we test it, but for now, the launch shows that Sivga is continuing to refine its planar options while keeping the pricing within reach for most buyers.
