ZEN 4 IEM

Four Drivers. One Masterpiece.

This is not just an upgrade—it’s the pinnacle of Zen.

The Inearz Zen 4 fuses art and engineering into an in-ear experience that’s as precise as it is emotional. Powered by an expertly tuned 4-driver balanced armature system, Zen 4 delivers rich, deep bass, silky mids, and exhilarating highs—with the kind of detail that brings every mix to life.

This is the IEM that doesn’t just play music. It tells the whole story.

Let ADEL Take the Pressure Off

At the heart of Zen 4 lies ADEL™ Technology, a patented second eardrum system that eliminates harmful pneumatic pressure inside the ear canal. No more tightness. No more fatigue. Just full-spectrum audio that feels as good as it sounds.

Hear More, With Less
With ADEL, you get louder, more dynamic sound at significantly lower volumes. By reducing eardrum strain and eliminating the need to “crank it,” Zen 4 protects your hearing while giving you true-to-life clarity and enhanced loudness perception.

Expand Your Soundstage
Zen 4 lets you step inside your mix. The combination of multi-driver balance and ADEL’s natural spatial openness creates a wide, immersive soundstage that feels like you’re right there in the room.

Tune Your Isolation
Need to hear the room? Or block it all out? With swappable ADEL modules, you can tailor your level of isolation while maintaining bass response and full-spectrum fidelity. You can even drop in passive ambient filters and turn your Zen 4 into high-end custom earplugs.

Universal Fit, Custom Feel

The ergonomic shell is shaped for all-day comfort, and includes multiple replaceable tips to dial in your perfect fit. Whether you’re behind the decks, on stage, or just vibing out on a long flight—Zen 4 fits seamlessly and disappears into your workflow.

Built for Artists, Trusted by Pros
Hand-assembled with care by veteran technicians, the Zen 4 is designed to endure—and impress. With its aluminum-housed ADEL modules, road-ready durability, and sound tailored for artists, producers, and audiophiles alike, this IEM is a go-to tool for those who take their sound seriously.
