Cleer Audio Unveils Arc 4 Series World’s First THX® Certified Open-Ear True Wireless Earbuds

Cleer Audio—an award-winning force in high-performance headphones and smart speakers—raises the bar yet again with the launch of the Arc 4 and Arc 4+: the World’s First THX^® Certified Open-Ear True Wireless Earbuds. Supercharged with advanced spatial audio, the Arc Series now delivers Dolby Audio™, while Arc 4+ goes even further with Dolby Atmos^® for a fully immersive, next-level listening experience.

Engineered for listeners who refuse to compromise on sound, comfort, or intelligence—yet still expect real value—the Arc 4 Series takes the open-ear experience to the next level. The earbuds are 10% lighter, and the ear hooks 45% thinner than the Arc 3, creating a more ergonomic design that sits closer to the ear canal for unmatched open-ear sound, clarity, and comfort. Every note, every beat, and every detail comes through with astonishing precision, all at just $99.99 for the Arc 4, while the Arc 4+ delivers an elevated experience for $129.99.

With THX^® Headphone Certification, the Cleer ARC 4 Series sets a significantly higher standard for open-ear sound accuracy, clarity, and low distortion. This certification ensures a balanced frequency response with clear vocals, detailed highs, and impactful yet controlled bass, along with precise left/right channel matching for accurate imaging. Designed to maintain clarity even at higher volumes with minimal distortion, the earbuds meet THX’s specialized open-ear standards for optimized low-end performance. Each model is expertly tuned by THX engineers to deliver natural, high-fidelity sound that aligns with the THX optimal frequency response curve, providing a listening experience that is both immersive and true to the source.

The Arc 4 features Dolby Audio™ and Snapdragon^® Sound by Qualcomm^® for natural, clear, lag-free, and stable performance, while the Arc 4+ adds Dolby Atmos^® optimization and Dolby Sensor-built Head Tracking, which creates immersive spatial audio by using onboard sensors to detect head movement and keep the soundstage anchored. Dolby Audio™ delivers low distortion, natural sound, and accurate performance for both stereo and multichannel content, and Dolby Atmos^® optimization tunes the hardware for 3D object-based sound, providing precise playback of height and depth cues when enjoying Dolby Atmos content.

The Arc 4 Series delivers Hi-Res Audio with a 65Hz–40kHz frequency range, enhanced by Cleer’s DBE 4.0 (Dynamic Bass Enhancement) for deeper, richer lows and powerful bass. Powered by Bluetooth 5.4 and Snapdragon^® Sound, the earbuds provide fast, stable connectivity with multipoint support for seamless device switching. Qualcomm^® cVc (Clear Voice Capture) microphones improve voice calls by reducing background noise and canceling echo for crystal-clear conversations while preserving immersive audio. They also support aptX™ Lossless and voice control for ultra-clear wireless sound with precise detail.

The next-generation Arc 4 earbuds are 10% lighter than their predecessors—just 10.8 g per earbud—and feature a refined ergonomic hinge and softer materials for a secure, comfortable fit. The redesigned charging case is slimmer and pocket-friendly, offering easy portability while providing reliable protection and convenient charging for the earbuds.

The open-ear design allows users to enjoy premium sound while staying aware of their surroundings, perfect for commuting, work, or workouts. With an IPX7 water-resistance rating, the Arc 4 Series is built to handle sweat, rain, and everyday use. The Arc 4 delivers up to 32 hours of total playback (7–9 hours per charge plus 25 hours from the case), while the Arc 4+ extends battery life up to 34 hours and adds Dolby Head Tracking, Apple MFi^® certification, and physical on/off controls. Lightweight and portable at just 80 g including the case, the series combines comfort, endurance, and performance in a sleek, modern design.

The Cleer+ App lets users fine-tune their listening experience with customizable EQ, touch control mapping, and battery monitoring. The Arc 4+—available exclusively on Amazon—also comes in a distinctive pink finish alongside black and white, providing both advanced functionality and personal style.
