Reviews
"The Symphonium Audio Helios was what got me listening to all BA IEMs again. When I'm saying it broke stereotypes for me, I'm not kidding, I had to make sure that there were no dynamic drivers or electrostatic tweeters in these several times."
Symphonium Audio Helios Review — Headfonics
The technical reference
The Helios is a top-class statement product that represents a generational leap for us.
Renowned for its legendary technical prowess, the Helios defies the stereotypes commonly associated with multi-BA driver earphones. The Helios delivers an exceptionally clean sub-bass punch that hits hard without obscuring vocal clarity.
The Helios is tuned for a smooth and detailed midrange and also features first-class treble extension that pushes the boundaries of balanced armature tweeters. We've combined the best features of various monitors into one exceptional product.
Powered by an integrated TrueX™ 4-way crossover and FLAT™ technology, the Helios impresses with its dynamics and power, offering an unparalleled sound experience.
Tuned in collaboration with Subtonic
"There's a good chance this is the best-sounding kilobuck IEM currently on the market. With that in mind, I have no reservations about giving the Helios my seal of approval based on its sound quality."

Infinite linearity
With the Filtered Linear Attenuation Tuning (FLAT™) technology – a proprietary circuit developed in collaboration with Subtonic.
Through the synergistic cooperation with TrueX™ Thanks to Helios's 4-way crossover, the Helios is unaffected by impedance mismatches caused by different sources. You'll hear the same unobstructed sound regardless of the device you're using.
Premium cable
The Helios comes with high-quality Altalune Audio Nova 26AWG Type 2 Litz OCC copper cables, designed for an exceptional listening experience with excellent ergonomics and low impedance.Each cable is thought out down to the smallest detail, such as the solder used, and is made entirely by hand in Singapore.
Exceptionally durable
Constructed from a high-quality heat-treated T6-AL6061 aluminum alloy, the Helios is designed for durability and long-lasting performance. The T6 heat treatment significantly improves strength, hardness, and durability, while also increasing corrosion and fatigue resistance.This gives our IEMs the greatest possible strength and hardness and ensures that the Helios can withstand even the toughest usage conditions.
