Hi all,

We are proud to announce that the SJY Horizon Closed Carbon Planar Magnetic Headphones is now available for pre-order on Apos Audio.

We first heard the Horizon Closed at CanJam SoCal 2024, and we were immediate fans, we love the incredible detail, laser-precise imaging, and delightfully engaging tonality. Once you have tried it, we are sure you'll love it too.

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.

Hi all,

Some people get into headphones to chase the last half-percent of sonic perfection. Others just want cans that don’t make a grand piano sound like it’s coming through a drive-thru speaker. And then there’s Jeffrey Yin, who decided to rethink the whole thing. In our latest Q&A, we sit down with the SJY Audio founder to talk about why he landed on forged carbon fiber, what makes rectangular drivers a real advantage, and how the Horizon Closed Carbon went through 60 driver iterations before he was satisfied.

Here's the link to the site blog of the Q&A for more information: https://apos.audio/blogs/news/q-and-a-with-jeffrey-yin-of-sjy-audio

Anyone compared these to the Liric II?
I’ve got a V281 so I should be good for an amp for the SJY and portability isn’t required.
Just haven’t seen much feedback beyond the YouTube reviewers for the closed carbons.
