Short answer: the Binary 1900. Both are rated 4.4/5 for sound quality (#116 and #97 of 450 in-ear headphones), and the Binary 1900 costs $239.99 against $269.10 for the ZiiGaat Estrella, and with sound quality even, the cheaper one is the better buy.
The case for the Binary 1900: In the median of 4 squig.link measurements it tracks the target closely from 20 Hz through 3 kHz, with every band from sub-bass to upper mids within 1 dB, for a preference score of 78.5. The tradeoff: A 5.8 dB dip near 5.7 kHz and a presence band about 4.1 dB below target take the edge off vocals and guitar attack, making some recordings sound distant.
The case for the ZiiGaat Estrella: The median of 8 squig.link measurements shows one of the smoothest responses around, a 1.3 dB spread with a preference score of 79.0. The catch: Presence is about 3 dB low between 3 and 6 kHz, with a 4.7 dB dip near 5.8 kHz, so vocals and snare attack lose some bite and edge.
Buy the Binary 1900. Both are rated the same for sound quality, and it costs $29.11 less than the ZiiGaat Estrella.

Binary 1900: $239.99 Amazon eBay
Pros: In the median of 4 squig.link measurements it tracks the target closely from 20 Hz through 3 kHz, with every band from sub-bass to upper mids within 1 dB, for a preference score of 78.5. The dynamic driver paired with a passive radiator keeps bass extension full down to 20 Hz without overdoing it. At 124 dB SPL/V it gets loud easily from a phone dongle.
Cons: A 5.8 dB dip near 5.7 kHz and a presence band about 4.1 dB below target take the edge off vocals and guitar attack, making some recordings sound distant. Its 10 ohm impedance and high sensitivity make it prone to picking up background hiss from noisy sources.

ZiiGaat Estrella: $269.10 Amazon eBay
Pros: The median of 8 squig.link measurements shows one of the smoothest responses around, a 1.3 dB spread with a preference score of 79.0. Its two 10 mm dynamic drivers lift sub-bass and bass 1 to 1.6 dB above target, adding a gentle warm thump without muddying the mids, which sit almost exactly on target. A 6.1 dB lift in the air band near 11.5 kHz brings out sparkle and a sense of space at the top.
Cons: Presence is about 3 dB low between 3 and 6 kHz, with a 4.7 dB dip near 5.8 kHz, so vocals and snare attack lose some bite and edge. At 7 ohms it can pick up hiss or a shifted tonal balance on sources with high output impedance, so a clean, low-impedance output suits it best.
