SJY Horizon Closed Carbon Planar Magnetic Headphones

Note: This product currently has a 1 week fulfillment time. Jeffrey, a one-man operation, is manufacturing and testing each pair of Horizon Closed Carbon himself.

Sound unbound Designed and built in Houston, Texas, the Horizon Closed Carbon Headphones deliver a non-fatiguing, holographic sound with exceptional imaging and precise details. Made for audiophiles, music producers, and gamers needing image-perfect audio cues, the Horizon Closed Carbon combines the natural feel of open-back headphones with the noise isolation of a closed-back design.

Hand-made planar magnetic drivers Jeffrey Yin of SJY Audio hand-builds each driver with the strongest-grade magnets and a full aluminum frame, minimally dampening the driver to guarantee a playful, engaging, and image-perfect sound experience. This setup delivers outstanding performance with crystal clear vocals and a balanced sound across the frequency range.

Carbon fiber ear cups Hand-casted from forged carbon fiber, the ear cups sport a unique “brushstroke” pattern and extreme durability. The matte finish—both scratch- and finger-print resistant—perfectly complements the subtle and strong CNC-machined aluminum frame.

All-day lightweight wearability Built with CNC aluminum construction yet weighing just a pound, the Horizon Closed Carbon offers a sturdy yet lightweight design. Ultra-comfortable ear pads The earpads feature an interior of memory foam that contours to your head.

The outer layer combines perforated protein leather on the inside and non-perforated protein leather on the outside, while the front is made from breathable polyester to reduce heat for a cool and comfortable experience even during all-day use. Full-grain leather headband The top strap is crafted from full-grain leather, chosen for its natural texture and softness, while the bottom strap features thicker full-grain leather with a heavier finish, for its wear resistance.

Together, they form a two-layer construction, boasting long-lasting durability and a classic, refined aesthetic. How we’re listening to it Tom at Apos here.

I first heard the Horizon Closed at CanJam SoCal 2024. I was an immediate fan, loving it for its incredible detail, laser-precise imaging, and delightfully engaging tonality.

I’ve become an even bigger fan since getting to know Jeffrey Yin of SJY and getting a pair of my own to try with my setup at home, where I’ve listened to it for dozens of hours on end. Truly, it’s my favorite headphone I’ve heard in a long time.

While the Horizon Closed sounds great on almost any setup, it really shines with dedicated DAC/amp systems. It's sensitive enough to work with my iPhone 16 Pro and the Moondrop Dawn Pro dongle DAC (though I have to max out the volume).

It also sounds great on hybrid tube amps like the Gremlin, but I much prefer it with solid state amps. Some of my favorite pairings are the FiiO M17, TOPPING D90 stack, xDuoo XA-02 Class-A DAC/Amp, and R2R DACs like the FiiO K11 R2R or Denafrips Ares II.

A paradigm shift. " -Joshua Valour "Really, really great headphones--from the quality of materials to the tonality and tuning.

I simply love them. They absolutely sound great--well-balanced, maturely-tuned, and very, very pleasant to listen to.

" -iiWi Reviews “One of the best closed-back headphones I’ve heard around $1,000. They sound so unclosed—it’s phenomenal.

They’re a very comfortable headphone. The most impressive thing about the Carbon’s tuning is that everything’s balanced beautifully across the entire frequency range.

The thing that impresses me most is that they do not sound closed. They sound more like intimate open-backs.

They’re more neutral than the ZMF Bokeh, as well as being more open and spacious-sounding, which makes them insanely good gaming headphones. ” -Passion for Sound "A special headphone.
