R2 Series Universal In-Ear Monitors (IEMs) – Premium Sound, Military-Grade Comfort, and Studio Reference Quality

by Rocky Sharma

Introducing the R2 Series Universal In-Ear Monitors (IEMs)

When it comes to finding the best universal in-ear monitors for musicians, audiophiles, and anyone who values pristine audio quality, the R2 Series stands out as the top choice. Born from our commitment to combining minimalist design with professional-grade sound, the R2 Series IEMs are engineered for users who demand comfort, durability, and reference studio acoustics.

Designed for Audiophiles, Musicians, and Professionals

The R2 Series began as an alternative to traditional in-ear monitors, blending the familiar feel of regular earphones with the advanced performance of custom IEMs. Utilizing our proprietary tuned balanced armature drivers, the R2 delivers the precise, transparent, and natural sound signature demanded by studio professionals and touring artists.

Military-Grade Comfort with EarLock® Retention System Licensed from SureFire®

One of the most unique features of the R2 Series is the EarLock® retention kit—a patented design used by U.S. military special forces. The EarLock® system utilizes seven secure contact points to lock each earpiece in place, providing a consistent, ultra-comfortable fit that stays secure during any performance or workout. The hypoallergenic silicone ensures hours of irritation-free use, making the R2 perfect for long sessions in the studio or on stage.

Premium Construction, Minimalist Aesthetics

Each R2 IEM is crafted from lightweight, aircraft-grade aluminum alloy combined with a high-durability polymer. The minimalist casing is both sleek and rugged, finished with a protective anodized coating and a subtle, laser-etched logo for a clean, uncluttered look.

Studio Reference Audio, Tuned by Industry Experts

All R2 Series monitors are tuned in our California and Nashville studios by leading music and recording professionals. Using balanced armature drivers from Knowles®—the global leader in high-fidelity audio components—these IEMs deliver a studio reference acoustic signature for accurate, detailed sound in any environment.

Detachable MMCX Cables & Premium Oxygen-Free Copper

The R2 features detachable MMCX connectors, allowing easy cable swaps to suit different devices and applications. The supplied cable is a multi-braided, Kevlar-reinforced monocrystalline oxygen-free copper design, engineered to reduce cable noise and preserve maximum audio quality. A 3-button in-line mic offers full compatibility with iOS and Android devices for calls and playback control.

Customizable Fit, Maximum Sound Isolation

Each set includes multiple sizes of non-allergic silicone ear gels and Comply™ T-100 premium memory foam tips, enabling a truly personalized fit. Achieve up to 24dB of noise attenuation—making these the ideal in-ear monitors for stage, studio, or travel.

Assembled in the USA
