Cleer Audio has introduced its new Arc 4 series true wireless earbuds, which the company says are the “world’s first” THX certified open-ear buds.
The line includes the Arc 4 and the Arc 4+, both of which come with advanced spatial audio capabilities. They deliver Dolby Audio while the Arc 4+ adds Dolby Atmos for an even more immersive listening experience.
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 open-ear sound, clarity, and comfort.
With THX Headphone Certification, the Cleer Arc 4 series is ensured to offer 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 as we;;. Each model is expertly tuned by THX engineers to deliver natural, high-fidelity sound that aligns with the THX optimal frequency response curve.
Along with Dolby Audio, the Arc 4 features Snapdragon Sound by Qualcomm for natural, clear, lag-free, and stable performance, while the Arc 4+’s Dolby Atmos optimization is complemented by 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.
Along with being lighter than their predecessor at just 10.8 grams per earbud, the Arc 4 and feature a refined ergonomic hinge and softer materials for a secure, comfortable fit. The redesigned charging case is slimmer and pocket-friendly as well.
The open-ear design allows you to enjoy premium sound while staying aware of your surroundings, perfect for commuting, work, or workouts. With an IPX7 water-resistance rating, the Arc 4 Series can 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 also adds Apple MFi certification and physical on/off controls. It’s lightweight and portable at just 80 grams including the case.
Use the Cleer+ app to fine-tune listening with customizable EQ, touch control mapping, and battery monitoring. The Arc 4+ comes in a pink finish alongside black and white.
The Cleer Arc 4 wireless earbuds are U$100 and the Arc 4+ US$130.
