The OnePlus Bullets Wireless Z3 is engineered for those who demand a seamless blend of endurance and audio quality. At its core are 12.4mm dynamic bass drivers enhanced by the OnePlus BassWave™ algorithm, delivering rich, deep bass without distortion. For a more tailored listening experience, the Sound Master EQ offers four distinct modes: Balanced, Serenade, Bass, and Bold, while 3D Spatial Audio creates an immersive soundstage that puts you in the center of your music. Designed for the active user, the Z3 is built to withstand the rigors of daily workouts and outdoor adventures. With an IP55 rating for water and sweat resistance, it is protected against splashes and dust, ensuring your soundtrack keeps playing through rain-soaked runs or intense gym sessions. The neckband is crafted from skin-friendly silicone with an ergonomically curved design, weighing approximately 26g for a lightweight, all-day fit. Battery anxiety is a thing of the past with the Z3's massive endurance. A full charge provides up to 36 hours of music playback and 21 hours of talk time. When you're in a rush, the ultra-fast charging via USB-C delivers roughly 27 hours of playback in only 10 minutes, making it one of the most efficient neckbands in its class. Connectivity is modernized with Bluetooth 5.4, offering a stable wireless range of up to 10 meters and support for AAC and SBC codecs. Android users benefit from Google Fast Pair for near-instant setup. For calls, AI-powered Environmental Noise Cancellation (ENC) filters out background noise to ensure your voice remains crystal clear, while magnetic earbuds provide a convenient way to auto play/pause music and prevent tangles when not in use.
