HeartField CU8
Harman-Tuned Neutral Sound
The CU8 is meticulously tuned to the Harman neutral target curve and verified with professional artificial-ear measurements. From 20 Hz to 20 kHz, it delivers uncolored, faithful reproduction—whether you’re phase-matching on a master track or enjoying uncompressed audio, you’ll experience studio-monitor–level precision and detail.
PUR Vibration Control System
Equipped with micro-alloy spring suspensions on its mid and low-frequency drivers, the CU8’s PUR Vibration Control System lowers resonance points to enhance density and dynamics. Remarkably, just four balanced armature units achieve the richness and impact you’d expect from configurations with twice as many drivers.
Gold-Plated Brass Acoustic Chamber
Crafted from precision-milled brass with a density of 8.96 g/cm³—over three times that of standard resin—the CU8’s housing suppresses unwanted vibrations and elevates both tactile feel and acoustic clarity. This rigid chamber ensures the purest signal path from driver to ear.
Artisanal Hand-Finishing
Every pair of CU8 earphones is shaped and polished by skilled hands. Through careful hammering, grinding, and buffing, each unit becomes a fusion of audio engineering and artisanal artistry—time-honored craftsmanship encoded in metal and form.
Premium Detachable Cable
The detachable cable features 24 AWG silver-plated, oxygen-free copper (40 strands of 0.005 mm wire per core) with PTFE insulation (dielectric constant 2.1) to minimize distortion. WBT silver-alloy solder ensures rock-solid connections and transparent, full-bandwidth transmission.

Customers have to bear any form of custom/import/processing fees that are applicable for your parcel.
