Is the Quad Driver Still Good in 2026? Long-Term Review

Introduction

It's easy to get swept up by the hype of freshly released audio gear, but I've always been more interested in how equipment actually holds up over time. The Quad Driver earphones—originally released by 1MORE—made waves with their four-driver setup and premium design language. Back when I first picked them up, they were already a bit of a legend on audio forums. Fast forward to 2026, and a sea of competitors now crowd the mid-to-premium range. But has the Quad Driver faded into obscurity? After using these IEMs (in-ear monitors) for well over a year as my daily driver, here's an honest, hands-on, and up-to-date review for anyone wondering if they're still worth your money—or a spot in your rotation.

About the Quad Driver

1MORE’s Quad Driver earphones were originally pitched as a bridge between true audiophile IEMs and stylish consumer buds. With four drivers (one diamond-like carbon dynamic driver and three balanced armatures), a robust aluminum build, Kevlar-reinforced cable, ergonomic angled nozzles, and THX-certification at one point, they weren’t just chasing specs. They were beloved for their consistent tuning and approachability.

I started using the Quad Driver with realistic expectations rather than subjecting them to "audiophile myth-making." My primary intention was to see if they could handle a bit of everything: portable listening, travel, desk work, and even some less common use cases like casual mobile gaming and video conferencing. Here’s what I found over months of use in 2025 and 2026.

Design & Build Quality

First things first: The Quad Driver still feels like a little luxury item. The aluminum alloy housings (with red accents) have avoided scratches, even when carelessly tossed into pockets or my bag. The tactile buttons on the inline control remain responsive, and the cable—reinforced with Kevlar—shows incredibly minimal fraying despite daily winding, light yanking, and more "real world" abuses.

My only disappointment was the somewhat rigid neck cinch and the Y-split area, which feels chunky even after prolonged break-in. The ear tips have lasted, but the included foams lost their rebound after a few months, forcing me to switch to aftermarket alternatives.

Sound: How Does It Hold Up?

To my ears, the sound signature of the Quad Driver is best described as a fun, slightly V-shaped tuning with a clearly elevated sub-bass, engaging upper mids, and a safe (but occasionally piercing) lower treble. I mainly compared it to two other popular IEMs in my collection: the Moondrop Aria (single DD) and the Final E500 (budget favorite).

The Quad Driver’s bass is punchy but not bloated; fast electronic music never feels muddy. Acoustic and vocal tracks shine too—to a point. On some modern pop, the lower-treble can sizzle, especially at higher volumes, but I got used to it over time.

The soundstage is wider than you’d expect for this form factor—outclassing similarly priced wireless buds by a mile—but obviously, it doesn’t match open-back headphones. Imaging is accurate enough for gaming, though hardcore FPS players might seek something even more precise. Where it really stands out is its extension up top: airy, detailed, and always musical. I’d argue it still holds its ground vs. newer IEMs under $200, though not without caveats.

Long-Term Comfort and Ergonomics

Ear fatigue is a real consideration, especially with the semi-rigid design. After 2-3 hour sessions, I sometimes noticed some discomfort where the housing presses against the concha—partly due to the size and partly due to my ears. The selection of ear tips in the box is generous, but I eventually settled on larger foam tips for better seal and isolation.

I frequently used the Quad Driver for video calls (teams and Zoom) as well as running errands, and the microphone quality held up decently—callers always reported that I sounded clear, though road noise could leak in. Passive isolation is solid, but these are not ANC earphones; don’t expect airplane-level hush.

Durability: A Real-World Perspective

This is where the Quad Driver impressed me more than expected. After a year of being crammed in jacket pockets, yanked from phone jacks, twisted inside desk drawers, and exposed to summer humidity and winter chill, the housing and cable show minimal aging. No weird channel imbalances, no driver flex. The L-shaped jack survived multiple device swaps, and the strain reliefs have so far resisted tearing (a pleasant change from cheaper earphones).

The only real wear came from the ear tips (as mentioned) and a loosening around the three-button inline controls, which started to rattle slightly after months of fidgeting. Not a functional problem but a minor sensory annoyance.

Compatibility & Use Cases in 2026

One of the Quad Driver’s unfortunate relics: the old-school 3.5mm jack. If you use a modern phone, you’ll likely need a dongle or DAC. On my recent Android, I used a USB-C DAC dongle with no issues, and the Quad Driver paired well with both Windows notebooks and my DAC/amp combo at home. For travel, this IEM was pretty much plug-and-play—aside from that dongle “archeology” so common nowadays.

The in-line remote worked for calls, volume, track control on Android and older iPads, but iPhone users (post-headphone-jack) are out of luck unless you're running through an adapter.

Pros & Cons: My Honest Take

• Pros:
  • Robust, premium build—no cracks or cable breaks in a year of use
  • Balanced, engaging sound signature with good staging for IEMs
  • Wide selection of included ear tips for fit customization
  • Strong passive noise isolation
  • Mic and inline controls actually function on Android/macOS/PC
  • Excellent detail retrieval in the treble—microphone is clear for calls
  • Still beats typical wireless buds in overall fidelity (if you don’t mind wires)
• Cons:
  • 3.5mm jack means dongle life (or DAC) for most modern phones
  • Slight rigidity of the cable and big Y-split can get annoying
  • Ear fatigue can set in if housings don’t fit your ear shape
  • Foam tips degrade relatively quickly under heavy use
  • Piercing lower treble on some tracks, especially at high volumes
  • Outdated “flagship” status—some new IEMs offer more for less, if you want a different sound signature

Comparison with Other Popular IEMs

Should You Still Buy the Quad Driver in 2026? A Buying Guide

Who Should Consider It?

If you’re after a fun, robustly built, and still-unique IEM with a lively sound that handles anything from hip hop to house, the Quad Driver remains a solid pick—especially if you can find it at a discount. Its build quality has outlasted expectations, and in an era when truly good wired IEMs under $150 are getting rarer (replaced by wireless buds that trade fidelity for battery life), the Quad Driver offers enduring value.

These are also perfect for desk warriors or hybrid workers who want something reliable for both music and conference calls—though not my first choice for marathon listening sessions due to comfort nuances.

When to Look Elsewhere

• If you need wireless, obviously look elsewhere (these are wired-only, no adapters included)
• If your ears are sensitive to energetic treble, or if you crave a "warm and relaxed" sound, one-driver sets like the Aria or Final E500 may suit you better
• Those who want to avoid dongles entirely due to the 3.5mm plug
• If you want the bleeding edge of tuning and tech—new models in 2026 might have more advanced drivers or boutique features at similar prices

What to Watch For

• Check that you’re getting a genuine product—counterfeits were somewhat common in past years
• Look for sales or open-box deals, as the Quad Driver’s price often fluctuates year to year
• Consider investing in aftermarket tips—spin-fits, foams, or custom molds can extend comfort and isolation
• If your device lacks a headphone jack, factor in the cost of a decent USB-C or Lightning DAC/adapter

Conclusion

It’s rare for consumer audio products to age this gracefully, but the Quad Driver makes a strong case for itself in 2026. While flashier IEMs have launched, and wireless is capturing headlines, I found these earphones unwaveringly reliable and musically satisfying for the price—warts and all. Their durability, vibrant sound, and overall utility kept them in my pocket long after the “honeymoon phase” ended. Not flawless, not the newest—and maybe not for every taste—but for those still rocking wired gear or seeking something with proven staying power, the Quad Driver holds up remarkably well in 2026.
