FLAT + PHAT
Featuring a combination of our finest technologies, the Crimson boasts a fusion of both PHAT and FLAT advancements.
With PHAT technology ensuring no unnecessary frequency inversions or phase cancellation, and FLAT technology ensuring low impedance and immunity from impedance mismatch, the Crimson is ready to take on any challenge thrown its way.
PHAT™: Phase Harmony Attenuation Technology (PHAT), developed by Symphonium Audio, reduces any possible undesirable phase cancellation or frequency inversions present between drivers. This requires rigorous driver selection and circuit implementation in order to achieve the desired driver synergy. The result is a class-leading treble response past 10khz well into 20khz and beyond.
FLAT™: Our proprietary circuit design proudly developed in-house with Subtonic. Filtered Linear Attenuation Tuning (FLAT) Technology ensures a flat and linear impedance curve across the frequency range. The result is an IEM that sounds consistent across varying source devices, free from frequency response change due to impedance mismatch. A true hallmark of engineering excellence.
Refined Shell Design
A different design language means a different look.
The Crimson presents a redesigned shell, refined through extensive community feedback. The shell is now thoughtfully shaped to comfortably fit smaller ears, featuring a shorter nozzle and a gently rounded form.
The outcome is an IEM that rests snugly against the ears, ensuring a seamless fit. Made from the same high-grade T6 heat-treated AL6061 Aluminium alloy, the Crimson is engineered for durability and long-lasting performance.
Forged Carbon
The Crimson boasts a new colour scheme and a premium forged carbon faceplate that pays homage to our brand's origins and resilience.
This material composite has graced the works of award-winning jewelry, watch, and luxury vehicles. Due to the material's inherent nature, each faceplate is a unique masterpiece, ensuring no two sets are the same.
Given the Crimson's status within the Symphonium lineup, it's only fitting that this distinctive and premium material finds its place within the design.
Exclusive Cable With Ultimate Versatility
The Crimson Earphone comes with an exclusive Altalune Audio Novaron 26AWG Type 2 Litz OCC copper cable.
This Symphonium Crimson exclusive variant of the Novaron features a unique construction to complement the Crimson. Choose between a 4-wire or 8-wire configuration to best fit your needs.
Each exclusive Altalune Novaron cable comes terminated with super low impedance OE interchangable plugs with both 3.5mm and 4.4mm version heads, allowing for compatibility with myriad source devices on top of offering futureproof flexibility.
TrueX™ 4-Way Crossover
By utilizing a true 4-way crossover, we are able to tune each driver to the exact specifications we require to achieve the best possible sound.
A testament to our highest engineering standards, TrueX Crossovers boast an electrically isolated signal path for each driver in our multi-driver designs. Every component is chosen and placed with intent in our electrical designs to provide the correct signal to the optimal driver. No inflated crossover number counts or quasi-crossover designs found here; just pure engineering excellence for an uncompromised audio experience.
PrecisionMatch™
Each earphone undergoes rigorous channel matching and reference matching with PrecisionMatch™ technology to guarantee a superior listening experience.
With strict quality control standards, every earphone is individually measured on an B&K 4195-Q; IEC 60318-4 coupler and compared against a strict reference with industry leading software before being sorted to best-matching pairs. Symphonium's PrecisionMatch ensures each set of earphones adhere to a strict reference curve with minimal unit variance — a feat made possible only through the expertise of our highly skilled technicians.
Quality Ear Tips
Paired with a comprehensive set of Azla Sednafit Standard and Divinus Velvet Eartips, the Crimson ensures a great fit for every listener.
