Description
The Technical Reference
The Helios is a statement class product that marked a generational leap for Symhonium. Recognized for its technical ability, the Helios disproves the stereotypes commonly associated with multi-balanced armature (BA) driver earphones. It offers an exceptionally clean sub-bass punch that hits hard, without colouring the clarity of vocal presentations.
Tuned in collaboration with Subtonic for a smooth and detailed midrange, the Helios also features class-leading treble extension that pushes the limits of balanced armature tweeters. We combined the best features from different monitors into one exceptional product.
Powered by an integrated TrueX™ 4-Way crossover and FLAT™ technology, the Helios is sure to impress with its dynamism and vigour and will deliver an unrivalled audio experience.

- Tuned in Collaboration with Subtonic
- Anodized AL6061 Aluminium Shell
- Azla Sednafit Standard and Sednafit Short Eartips
- 26AWG Altalune Nova in 4 Wire Configuration
- Now available with interchangeable OE plug 3.5mm and 4.4mm terminations
- Hand-Crafted in Singapore
Infinite Linearity
Helios features Filtered Linear Attenuation Tuning (FLAT™) Technology — a proprietary circuit developed in-house with Subtonic. It ensures a flat and linear impedance curve across the frequency range.
Working synergistically with Helios’s TrueX™ 4-way crossover, the Helios will not be affected by impedance mismatch due to difference in source used. 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.
Premium Cable
The Helios comes bundled with premium quality Altalune Audio Nova 26AWG Type 2 Litz OCC copper cables that are designed to deliver an exceptional listening experience with great ergonomics and low impedance.
Each cable is designed down to the finest details such as solder used and are completely hand built in Singapore.
Exceptionally Durable
Crafted from high-grade T6 heat-treated AL6061 Aluminium alloy, the Helios is engineered for durability and long-lasting performance. The T6 heat treatment significantly improves its strength, hardness, and durability while also enhancing its resistance to corrosion and fatigue. This gives the maximum possible strength and hardness for our IEMs, ensuring that the Helios can withstand even the most rigorous use.
Whether you're performing on stage or listening on the go, the Helios Earphone is built to last.
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 Eartips
To squeeze out every last bit of performance, the Helios comes with Azla Sednafit Standards for an uncompromised listening experience.
