7HZ Sonus – 1DD+1BA Hybrid IEM

7HZ Sonus 1DD+1BA Hybrid IEM

Many hybrid IEMs have an audible transition zone between the dynamic driver and the BA, a coherence gap you notice in vocals or upper mids. The 7HZ Sonus was built around that specific problem: one BA and one dynamic driver, tuned to sound like a single unit.

1DD+1BA hybrid driver: coherence over complexity

Combining a dynamic driver (DD) with a balanced armature (BA) usually brings an integration problem: timbre and tonality that shift character depending on the frequency, because each driver reproduces a different part of the spectrum. The Sonus focuses on acoustic and electrical engineering built to merge the two into a continuous response, instead of stacking more BAs to paper over the gap. Fewer drivers, tuned to work as one.

10Hz-20kHz response and THD below 1%

Full coverage of the audible spectrum, from 10Hz to 20kHz, with total harmonic distortion (THD) below 1%. In practice, bass hits with impact and speed without losing definition, and the finer details in a recording don’t get lost in the noise. 30Ω impedance and 109dB/V sensitivity make the Sonus easy to drive from a phone or a simple dongle, no dedicated amp needed.

Construction: medical-grade front chamber, aviation-grade aluminum back

The front chamber uses a medical-grade material, chosen both to optimize sound propagation and to be safe for extended skin contact. The back is aviation-grade aluminum, light but durable. The shape was designed from molds of the human ear canal, for a comfortable fit in long sessions without having to think about it.

Detachable silver-plated OCC cable

The included cable is silver-plated OCC (single-crystal copper), with 49 wires per core in a 4-core braided structure. It’s light and built to maximize signal transmission. Being detachable (0.78mm 2-pin connector), you can swap it for a different cable later, and the swap also protects the IEM’s lifespan if the cable wears out first.

GAMER UNLOCKED TEAM’S TAKE

The 7HZ Sonus makes sense if you want to try a hybrid without paying for multi-BA complexity: one well-tuned DD and one well-tuned BA usually sound more coherent than configurations with more, less integrated drivers.

⚠️ Color and microphone: we only stock the black version, no microphone. The cable is detachable, so you can add a mic cable from another maker later if you need one.
