Rossi&Wing (LUA) Celestian Review: Serene Bliss
From budget to flagships, many IEMs and headphone makers approach from here and there – and as the industry gets more competitive and condensed, the stronger the demands to stay afloat to the community’s attention. Other than the sound signature, what else do you pay attention to the most when choosing an IEM? Driver types, brand power, or price to performance – or perhaps all of them? Today, we’re reviewing the Celestian – the flagship IEM of the LUA series by Rossi&Wing. Celestian is priced at $1880 and is powered by hybrid drivers, including R&W “Magna Resonus” MR10 dynamic driver.
Rossi&Wing: Who Are They?
Since Rossi&Wing (R&W in short) should be a completely new face to most users in the audiophile scene, let’s briefly go through the brand introduction. The title “ROSSI” refers to a group of members who have extensive experience in R&D, providing tuning and production services for numerous well-known audio brands over the past decades. While R&W hasn’t described the specifics of the R&D team members or which brands they’ve worked for, presumably due to NDA, R&W shed light that the team (or at least a portion of them) is based in the United States.
On the other hand, “Wing” is the last name of Zephon Wing, the founder and the head leader of R&W, as well as Archwing Audio Emporium, a portable audio distributor business from Taiwan. Rossi and Wing have teamed up starting 2019 for several years until finalizing their product line-up as well as their debut product, the First Light: the summit-fi IEM. Well, to be exact, it’s an “IEA” (In-Ear Auditorium). If you’d like to learn more about First Light and the story behind being an IEA instead of an IEM, you can read our review here.
LUA – Powered by Rossi&Wing
Rossi&Wing currently has three product lines, which are the Celestisium Series, Sanctorum Series, and LUA Series. The Celestisium Series is R&W’s most high-end in-ear product line-up, including First Light and Four Winds (TBD 2026). The Sanctorum Series is the premium cable line-up, and lastly, the LUA Series is a line of premium in‑ear monitors that blend advanced driver engineering with artistic design. Positioned as a luxury collection, LUA IEMs emphasize three multisensory concepts, uniting sound, visual art, and fragrance. LUA Celestian is available in two variants – Van Gogh and Mondrian.
Two Color Variants – Van Gogh and Mondrian
The Van Gogh Edition is the default color option that contains orange and green color spectrums. The Mondrian Edition depicts the Mondrian-style artwork on the faceplate as well as the body color swapped with silvery glitter resin. Colors are the only differences, and both versions are sonically identical. Obvious as it is, we’re reviewing the Mondrian Edition here.
Artistic Packaging of Celestian
Celestian arrives in a unique packaging box where the earpieces are displayed within a photo frame. Included with the IEMs are 3 pairs of silicone tips, a 2pin-4.4mm cable, paperwork, a R&W leather case, a glass display stand, a Japanese Furoshiki protective cloth, and a fragrance sample. As hinted earlier, Rossi&Wing paired LUA products with a curated fragrance (HOKKI fragrances) to extend the unboxing into a full sensory experience, which is specifically selected for Celestian. Inside the box, as well as the Furoshiki cloth, gently exudes a unique fragrance. The earpieces also have this scent, though it gradually disappears – no worries in case you dislike fragrances, if that’s the case.
Earpieces that are Absolutely Artistic
Let’s first talk about the design – here we’ll mostly focus on the Mondrian Edition as it’s the one we’re dealing with here. Celestian uses a resin body infused with silver glitter, giving the earpieces a subtle shimmer that complements their artistic faceplates. The Mondrian Edition, which we’re reviewing here, features a vibrant mosaic of red, blue, and yellow blocks, inspired by the iconic Mondrian art style. The faceplates are topped with metal LUA and R&W logos. The Van Gogh Edition, on the other hand, takes a more organic approach with orange and green tones, evoking a warmer and more nature-inspired aesthetic.
In terms of fit, the shells are light and ergonomically shaped, sitting comfortably in the ear without protruding. The size is standard or slightly more compact than typical flagship IEMs, making them easy to wear for extended sessions. There is a bit of ear pressure buildup, more than average, though not to a concerning degree. Nonetheless, it’s not a dealbreaker, though I do wish the IEMs themselves were more convenient in relieving pressures in the first place. Using pressure-relieving eartips like Velvet Tips or Tanchjim T-APB greatly helps mitigate this, and the included stock tips are already tuned for this purpose.
As for the technical specifications of Celestian, unfortunately, we don’t have much info available to discuss here – R&W keeps the internal driver configuration of the LUA Series under wraps, except that they’re powered by the ‘R&W Magna Resonus MR10’ driver. Though based on the sound characteristics and nozzle design, Celestian likely uses a 1DD+2BA setup, with a 10mm custom dynamic driver at its core. Celestian has a 2-bore design for the nozzles, and the cable connection is flushed 2-pins.
Stock Cable: Rossi&Wing GaZe
Celestian now comes paired with R&W’s updated GaZe cable, replacing the earlier black fabric-shielded stock cable. The GaZe cable is a copper-silver hybrid coaxial design, built with OCC Copper and OCC Silver-Plated Copper. It’s a 2-braid cable with a smooth gray finish, offering both visual elegance and functional flexibility. Cable termination is 2-pin to 4.4mm, with a brushed-hairline metal Y-split shaped like a triangular prism pillar. The plug design is subtly unique, featuring a circular column with a slightly thicker midsection that sets it apart from typical plug shapes. Handling is excellent – soft, pliable, and microphonics-free. The cable complements Celestian’s aesthetic and sonic character well, and the build quality feels premium without being overly stiff or heavy.
