Symphonium Helios

Featuring Filtered Linear Attenuation Tuning (FLAT) Technology, a propriety circuit developed in-house with Subtonic, Helios will not be affected by impedence mismatch due to difference in source used. You will be able to listen to the same unimpeded sound regardless of the device you are using.

Tuned in collaboration with 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.

A great earphone deserves a cable of equal quality.

As such, each Helios comes with a low impedance hand-built 26 AWG OCC Copper cable from Altalune Audio that has been carefully designed - down to the solder used - to provide the best listening experience possible.

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.

By utilizing a 4-way crossover, we are able to tune each driver to the exact specifications we require, achieving the best possible sound

We only use the highest quality Panasonic and Vishay components; they are further hand-matched to attain better channel matching.

To squeeze out every bit of performance, Triton comes with standard AZLA Sedna Earfit tips, for uncompromised listening experience.

Blown away by the shipping

Shipped out on 30th Dec, in the middle of their year end break no less. Reached me in NJ the next day! Incredible. You know the level of service you're getting with Elise Audio. About the IEMs themselves - brilliant, incisive and detailed. And do they pack a punch or two. Symphonium are on a bit of a roll with their kilobuck range. Very pleased.
