The Jays Audio x ZiiGaat Estrella delivers a thrilling V-shaped signature that prioritizes fun and engagement. Its standout feature is the commanding sub-bass, powered by dual dynamic drivers, which delivers seismic rumble and physical impact without bleeding into the mids—perfect for bass enthusiasts seeking both power and control. Mids remain clear and forward enough for vocals to cut through, though they occasionally take a backseat to the low-end spectacle, leaning toward a warm, lush presentation.

Treble shines with energetic sparkle and strong extension, enhancing micro-details and air, though its peakiness can induce fatigue in longer sessions or with bright tracks. Technically, the Estrella impresses at its price with expansive soundstage width, precise imaging, and detail retrieval rivaling costlier models, though timbre can occasionally skew artificial in complex passages. The lightweight resin shells ensure comfort, but the accessory package disappoints—the flimsy stock cable and mediocre tips demand aftermarket upgrades.

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.

Probably the most detailed and technical IEM around $300. You pay for the detail with a fatiguing, sharp treble presentation. Looks and sounds great, IF you can handle it. Accessories are a straight up dissapointment.

A little bit overcooked. It is certainly not a bad IEM. It does a good job in give you a lot of bass and a lot of physicality in the bass and not compromising in separation and imaging.

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.
