So hot, it's Crimson hot. Symphonium Audio's latest flagship earphone is also their greatest, distilling everything they've learned from Meteor to Helios into one gem of performance and fit. How Symphonium could cram all that detail and performance into something as pint-sized as Crimson is a wonder to behold. After all, parts are inexpensive, whereas labour, innovation, original R&D, resourcefulness in making the most of what's available, love and passion for engineering, aren't. By optimising the acoustic architecture around 4 balanced armature drivers – tweaking crossovers, bore lengths, and chassis layout – Crimson emerges as the Symphonium of our dreams. [See Product Desc. For More] Indeed, its flat mid-range to treble transition comes courtesy of greater pinna gain, exhibiting a frequency response you can trust, incredible detail, and hyper-realistic live dynamics. Best of all, Crimson's fit is a dream come true. As a successor, and immediate upgrade, to Helios, Crimson answers all of its predecessor's critics. A flat frequency response transition from 1Khz up to 4Khz enhances the perception of more accurate, present mids. Despite Symphonium's increased pinna compensation and the eschewing of a more diffuse, distant soundstage, Crimson suffers no shortage of spatial technicalities. It renders images with solid, tangible outlines on a vast and black background.  It's amazing how so much soundstage was crammed into such a small shell – the other improvement Symphonium are likely to be greeted with much cheer for. With a critical re-arrangement of components within Crimson's cavity not only for sonic gains through Phase Harmony Attenuation Technology (PHAT), but also wearability, the best-fitting Symphonium yet can be worn by virtually all ears. What's left is pure performance distilled from miniature high-grade T6 heat-treated AL6061 aluminium alloy shells, housing Symphonium's trademark flat impedance technology that ensures Crimson's performance remains consistent with inconsistent voltage sources. Still, it bears to juice the low impedances of Crimson well for best performance. To that end, Questyle Audio's CMA18P DAC/amp is a mainstay, while HiBy Music's partnership with Symphonium has been explored at length with any of the latter's discrete output stage music players.

Crafted to deliver a thrilling, rumbling bass experience without compromising clarity in the treble, Titan boasts a smooth sound signature with an assertive, enveloping bass presence. With its powerful subbass, Titan delivers impactful lows that elevate tracks to new heights.But Titan isn't just about bass; it's about achieving a perfect balance across the entire frequency spectrum. Titan maintains accurate mids and highs without overly emphasizing either to compensate for the bass quantity. The result is a sound signature that is smooth, immersive, and undeniably addictive.

SYMPHONIUM X SUBTONIC"Representing a generational leap for us, Helios was designed to disprove the stereotypes associated with multi-driver balanced armature earphones. Utilising newly developed technologies, our balanced armature subwoofers produce exceptionally clean sub-bass punch that hits hard, yet does not colour vocal presentation. Tuned for a smooth and detailed midrange, the Helios also features class-leading treble extension that pushes the limits of what balanced armature tweeters are capable of. We combined the best features of different monitors into a single product. Powered by an integrated 4-Way crossover, the Helios is sure to impress with its dynamism and vigour. We never fail to push the limits." —Symphonium Audio    

Giant is an IEM built for those who crave a sense of scale in their music—vast, immersive, and full of depth. Inspired by the icy expanse of Jotunheim, it creates an atmosphere that feels open and boundless, as if you’re standing alone on a frozen peak with nothing but the wind and sky around you. The wide soundstage and precise imaging place every note in its own space, making the experience feel like a trek through towering glaciers and endless snowfields. Deep, resonant bass grounds the sound like the weight of ice underfoot, while crisp, airy highs cut through like the sharp mountain air. 1. CORE+™ Chambering System Symphonium Audio completely reworked the tuning with Giant, eliminating the need for tubes. CORE+™ pushes sound into uncharted territory with a precision 3D-printed tubeless chamber featuring multiple horns, each carefully engineered to shape and guide the flow of sound. 2. Refined Shell Design Giant debuts with a refined shell, sculpted through extensive community feedback fromCrimson’s design. More compact and contoured, it ensures a secure, comfortable fit even for smaller ears, while an improved nozzle lip prevents eartip slippage—keeping your listening experience secure and uninterrupted. 3. Pressure Relief Giant features pressure relief through a custom external venting design, facilitated byCORE+™, an evolution of our chambering technology. Venting IEMs have always been challenging for manufacturers particularly due to the risk ofdirt and dust accumulation from suboptimal venting hole placement. The issue was addressed with a unique venting method - venting through the socket area, which is less prone to touch in daily use. This innovative approach minimizes potential dirt and dust build up over time while ensuring pressure relief and optimal performance of the dynamic driver inside. First 100 Units launch edition comes with Dark Matter 4W cable first seen in our Europa Collab with Elise Audio. Subsequent units will be Giant’s 2W Twisted Pair stock cable. All cables will feature interchangeable connectors with 3.5 and 4.4mm plugs.
