FiiO, through its accessible Jade Audio sub-brand, has officially launched the JT7 open-back planar magnetic headphones, positioning it as the flagship model in a new duo aimed at democratizing high-end audio performance. Priced at an astonishing $119.99 (approximately €119.99 / £104.99), the JT7 represents one of the most compelling value propositions in the planar magnetic category to date, delivering in-house developed technology typically reserved for far more expensive models.
The JT7 arrives alongside the more budget-oriented JT3 dynamic-driver headphone, but it is the planar JT7 that steals the spotlight with its ambitious engineering. FiiO has fully developed the JT7’s driver from the ground up, featuring a large 95 x 86 mm planar magnetic transducer with an ultra-thin 3µm diaphragm – a thickness that enables lightning-fast transients, exceptional detail retrieval, and sparkling yet fatigue-free treble extension.
FiiO Elastic System
Key to the JT7’s performance is FiiO’s proprietary F.E.S. (FiiO Elastic System), an embossed multi-dimensional texture applied to the diaphragm surface. This innovative design mimics the elasticity of a dynamic driver’s surround, enhancing diaphragm movement for deeper, more authoritative bass without sacrificing the speed and clarity planars are known for. A push-pull dual-sided neodymium magnet array further ensures uniform drive force, contributing to the headphone’s impressive sensitivity of 92 dB/mW – making it remarkably easy to power from portable devices, phones, or modest desktop sources despite its low 18Ω impedance.
Harman-inspired tuning
Early impressions from the audiophile community have been overwhelmingly positive. Reviewers note that the JT7 delivers a balanced, Harman-inspired tuning with controlled treble that avoids the harshness or sibilance common in budget planars like the HiFiMan HE400SE. Bass is clean and extended, mids are natural and articulate, and the open-back design yields a spacious, holographic soundstage. Many are calling it a direct upgrade over popular sub-$200 options, with some even preferring it to FiiO’s own wood-cupped FT1 Pro dynamic headphone.
Build and comfort
Build and comfort further elevate the package. At just 318g, the JT7 shatters expectations for planar weight, incorporating a clever foldable structure for portability – a rarity in the category. Replaceable velvet earpads and headband cushion (secured via Velcro), aluminium construction, and detachable dual 3.5mm cable connections (with both 3.5mm single-ended and 4.4mm balanced cables included) add premium touches. Hi-Res Audio certification rounds out the credentials.
True Flagship
While the supporting JT3 open-back dynamic model (equipped with a 50mm PEK+PU composite driver, brass damping ring, and lightweight 330g design) targets an even lower entry point with punchy, resolved sound, the JT7 stands as the true flagship of the pair – proving that planar magnetic excellence no longer requires a four-figure investment.
The Jade Audio JT7 is available now through FiiO’s official channels and authorized retailers, including AliExpress and major hi-fi outlets.
For those seeking an accessible gateway into genuine high-end planar performance, the JT7 isn’t just competitive – it’s disruptive. FiiO continues to redefine what “budget” audiophile gear can achieve.
