Warmer Harman 2019 with less shouty vocals. Bassy all-rounder with decent tech. Build and plate design is very pretty... but price is a bit high and not that competitive - wait for sale unless you really dig the look. Jays Audio Youtube Channel

Reviewer Score
The Heartfield CU8 delivers a neutral sound that closely follows the Harman target curve, providing a balanced and accurate listening experience suitable for both critical monitoring and musical enjoyment. Its bass response is tight and textured, with a slight mid-bass bump that adds a touch of warmth without bleeding into the mids, while the treble remains smooth and free of sibilance.
Build quality is a standout, featuring a hand-finished brass chamber that feels premium but contributes to a heavier design, which might affect fit for some users during extended wear. The included cable is thin relative to the IEM's weight, though the deep recessed 2-pin connectors ensure a secure connection.
Overall, the CU8 excels with a natural timbre and cohesive presentation, making it a strong choice for those seeking an analytical yet engaging signature across genres, though its weight and sparse accessories are minor drawbacks. The PUR vibration control system effectively enhances dynamics, allowing its four balanced armatures to perform with the impact of more complex driver setups.

Clean, balanced, neutral sound with good layering and tech. Relaxing vocals, but lacks power and last bit of vocal extension. Bass has good controll, but lacks impact. Has sizzly planar timbre in the treble. Safe but forgettable. Jays Audio Youtube Channel

A detailed, engaging all-rounder that's exciting without being shouty or harsh. Smooth, neutral tuning with a bass boost, excellent bass quality, clean mids, forward vocals, and sparkly, incisive treble. Great detail. I wouldn’t change a thing.Gizaudio Axel original ranking
