The Helios presents incredible dynamics within the form factor of open-back headphones. Designed to replicate the sonic properties of an acoustic treated recording studio, the Helios delivers unparalleled tonal balance, shining every detail of every song at both high and ultra low frequencies. HaromonicDyne Helios - your solution to maximum high fidelity audio, wherever you go.
Equipped with a new and innovative custom 50mm composite diaphragm dynamic driver, the Helios offers an extreme frequency response of 10Hz to 40kHz. Going beyond the audible range of the human ear, the dynamic range of the Helios ensures you will never miss any details of any song.
We wanted to present a sound that was both accurate, and musical. We tuned the bass to be very precise yet deep enough to leave a satisfying rumble. The speed of the bass allows our transparent mids to shine through for those smooth vocals. The trebles shimmer like crystals and presents a detailed, while enjoyable, listen. Thanks to its 16 Ohms impedance, you can easily pair the sonic performance of the Helios with any device.
As its name suggests, the HarmonicDyne Helios presents a natural, detailed, and balanced sound that allows you to feel an incredible connection and transparency to the music. The power of our new custom drivers, matched with our expertise tuning makes for an amazing sound. Add this to the custom driver cavity and open-back design, and you’ve got acoustics that can parallel any studio recording room! Escape from your daily routines and engross yourself in the music.
The sound cavity has been carved out of one piece solid walnut wood to create a acoustic chamber that resonates with luxurious timbre. We specifically chose solid walnut not only because of their beautiful appearance, but because walnut wood is known for is Mahogany-like warmth in the mids with the punchy and resonant bass like that of rosewood. The mesh is constructed of SUS304 stainless steel to allow open flow without compromising on the integrity of the construction. The Helios is a true marriage of stylistic design and optimal acoustics.
Designed with the highest-quality materials for the metal headband and sandwiched with several layers of resonant dampening polymers, you’re ensured with a secure fit and cloud-like comfort. The lightweight and softbuild design means your long listening sessions will be pleasurable - without the pressure.
The innovative and ergonomically designed ear pads are crafted of high quality nanometer leather cushions, an ultra-lightweight and ultra-comfortable material that makes for a comfortable wear. Its geometric inner membrane design ensures a perfect seal for those tight basslines, while permitting airflow so your ears don’t get too stuffy.
We chose to use ultra-high purity copper wires for our cable to enhance the rich mids and punchy bassline. The balanced cable also means you can benefit from the extra voltage of your desired digital source. One upgraded cable is also available to upgrade your sound to another high level.

Ive been blown away by these headphones. I have a lot of audiophile grade headphones and these have taken their place as my daily driver. These are highly detailed, U shaped frequency headphones. They have the big sound of a large driver and are very lively. Separation on them is fantastic and imaging is excellent. Very exciting and fun sound. I love these headphones and cant wait for HarmonicDyne's next product.
