JUZEAR’s latest in-ear monitors, the Harrier, are making some noise, literally and figuratively. Priced at $329.99, these new IEMs come loaded with a total of nine drivers per ear, aiming to deliver a balanced, detailed, and bass-boosted listening experience. And if you're into frequency graphs and tuning talk, yes, these were shaped under the “Tuned with Squiglink” program, so you’re not flying blind when it comes to how they sound.

Let’s start with what’s inside. The Harrier features a tribrid driver setup, which means it mixes and matches different types of drivers to handle different parts of the sound spectrum. Each earpiece includes:

• 1 dynamic driver for bass
• 6 balanced armature (BA) drivers, including 2 from Knowles, for mids and highs
• 2 micro planar magnetic drivers for treble extension and detail

All of this is connected through a four-way crossover system and four separate acoustic ducts, designed to keep the drivers from stepping on each other’s toes. The idea here is to let each driver focus on its own frequency range—lows, mids, highs—so the sound stays clean and organized.

The Harrier follows a sound signature based on the IEF Neutral + Bass Boosted curve, which is pretty popular among audiophiles who like a balanced sound with a little extra low-end thump. In short: it’s tuned to be natural and clear but still fun.

Here’s what to expect:

• Bass that hits with weight but doesn’t smother everything else
• Midrange that’s smooth and detailed—great for vocals and instruments
• Treble that stays crisp without getting harsh

This type of tuning makes the Harrier a good fit for just about any genre—whether you're into jazz, metal, EDM, or just want to hear every detail in your favorite podcasts.

Design-wise, JUZEAR clearly wanted the Harrier to stand out. The faceplates are made from real Blue Tiger’s Eye stone, each one CNC-carved to create a shimmering, hawk-eye-inspired texture. No two pairs look exactly alike.

The rest of the shell is made using 3D DLP printing, a method that allows for a precise, ergonomic fit. They’re finished with metal ring accents and come in two color options—Blue or Yellow. The shape is designed to sit securely and comfortably, and the included ear tips help users dial in the right fit.

JUZEAR includes a hybrid cable made of silver-plated OCC and single-crystal copper wire. It uses 0.78mm 2-pin connectors and supports swappable plugs—you get both 3.5mm and 4.4mm terminations in the box. That means you’re good whether you’re plugging into a standard headphone jack or a balanced output on your fancy DAC/amp setup.

Also included: multiple ear tip options to help get a proper seal, which is essential for both comfort and sound quality.

At $329.99, the Harrier lands in that sweet spot between entry-level and ultra-premium IEMs. It’s competing in a space filled with other tribrids, hybrid BA/DD sets, and even planar options, but few in this price range offer this many drivers per side—especially with planar units in the mix.

So who’s this for? If you’ve been dabbling with dual or triple-driver IEMs and are curious what a more advanced setup can offer—without dropping over $500—the Harrier might catch your attention. We reviewed the Aful Performer 5+2 earlier this year, which also offers a hybrid multi-driver configuration at a slightly lower price point of $239.99 at Amazon.

But with nine drivers per side, including planar units, the Harrier takes things further in terms of complexity. It’s not the cheapest IEM out there, but for what it packs inside, it’s clearly aimed at audio enthusiasts looking for more technical headroom and a standout design.

The JUZEAR Harrier is available now for $329.99, and it ships with everything you need to get started: hybrid cable, swappable plugs, multiple tips, and a standout design.

It’s clearly built for listeners who care about both how their gear sounds and how it looks. With nine drivers per ear and tuning designed to balance fun and fidelity, it’s a pretty bold release for 2025—especially at this price point. Whether you’re deep into the IEM rabbit hole or just starting to explore beyond single-driver earbuds, the Harrier is definitely worth considering.
