II. Design of HELM Audio F2

HELM’s USA-designed, China-manufactured audio products, including the F2, showcase remarkable durability and quality. The F2’s solid all-metal construction, likely an aluminum alloy, fits together tightly for a robust feel. Its intriguing shape sparks curiosity about the driver’s layout.

The attention to detail in the fit and finish of the F2 is remarkable. The textured knurl provides a pleasant tactile sensation and aids grip and insertion. Despite its sleek appearance, the permanent cable connection feels exceptionally sturdy. Moreover, the nozzle of the F2 is comparatively shorter than many other in-ear monitors (IEMs), and its thick, notched collar securely holds the ear tips in place.

Comfort & Fit

The F2 earphones have a comfortable small-medium size that fits me perfectly. When held, the shells feel solid. The exceptional ergonomics ensure that the body does not touch my outer ear, resulting in a lightweight and comfortable experience.

These headphones stay securely in place, providing a good seal. However, the downward cables can be disrupted without an ear hook. The angle of the nozzle is designed to accommodate most ears effectively, even without the need for long nozzles that insert deeply.

III. Performance of HELM Audio F2

Experience the extraordinary synergy of the HELM F2 headphones. These headphones deliver unrivaled audio quality by combining a 6mm Planar Magnetic Driver with a 10mm traditional transducer dynamic driver. Enjoy enhanced transient response, an extended frequency range, and the deep bass that modern listeners crave.

With magnetic planar smoothness across the entire audio spectrum, the F2, free from harshness, showcases exceptional midrange and high-frequency detail. Meanwhile, HELM’s signature low-end impact remains intact, ensuring a revolutionary mobile earbud design that delivers rich, powerful sound. Embrace the perfect balance of innovation and performance with the HELM F2.

Sound Quality

The F2 earphones have a higher-than-usual impedance of 32 ohms and an impressive sensitivity of 103dB, making them easy to drive. The insertion depth is average and provides above-average passive sound isolation when combined with properly seated and sealed ear tips.

The sound is quite impressive when using the provided tips. While the clarity and fine detail are evident, the overall sound signature is more balanced and restrained than expected. Despite featuring a dedicated, dynamic driver for lower frequencies, the bass response is not overpowering.

Interestingly, with the F2, using ear tips with a wider bore and allowing less restriction in the sound flow through the tube yields a more pronounced bass response.


The bass extension of the F2 is deep and doesn’t exhibit any roll-off. I detected no distortion, even at moderate to loud volumes during testing. The resolution and texture are exceptionally well-suited for natural instruments like the cello and upright bass, providing a virtually perfect listening experience for my ears.


The midrange of the F2 is somewhat reserved and occasionally muted, making it a bit challenging to locate in the overall sound signature. There is a subtle presence of bass bleed that can slightly obscure the lower mid-frequencies. However, when the midrange is prominently presented in the mix, it sounds natural and shines through effectively.


The treble tuning and performance of the F2 have left a strong impression on me. It is advisable to look beyond the technical specifications as they do not sound lacking in the high-end department. The clarity and sharpness of detail are remarkable, especially considering their price range. Despite the high resolution, the F2 manages to avoid any issues with sibilance or a harsh presentation that can sometimes occur with planar drivers.

Noise Isolation

Discover the exceptional features of the HELM F2 headphones, designed to provide an unparalleled listening experience. With user-friendly simplicity, remarkable comfort, optimal sound isolation, and outstanding sound quality, the F2 sets a new benchmark in its class. Immerse yourself in a world of audio perfection where every detail is finely crafted for your utmost enjoyment.


The HELM Audio F2 features a strategically placed microphone on the cable, positioned near the mouth for optimal call quality, even in bustling surroundings. This thoughtful design ensures clear and crisp communication, allowing you to have conversations without any compromise, even in noisy environments. Whether you’re in a crowded office or on a busy street, the microphone’s location enhances the clarity of your voice, ensuring your calls are heard with remarkable precision and minimizing any disruptions caused by external noise. Say goodbye to muffled conversations and embrace crystal-clear communication with the HELM Audio F2.
