The JBL Tune 670NC is engineered for the everyday listener who demands a balance of premium sound and practical utility. Powered by 32mm dynamic drivers, these headphones deliver the signature JBL Pure Bass Sound, providing deep, punchy lows and clear mids that make them ideal for everything from high-energy music to professional podcasts. Designed to keep you focused in any environment, the Adaptive Noise Cancelling technology automatically adjusts to block out background chatter and traffic. For those moments when you need to stay connected to your surroundings, the Smart Ambient feature—including Ambient Aware and TalkThru—allows you to hear the world around you without removing your headset. Battery anxiety is a thing of the past with the Tune 670NC. Users can enjoy up to 70 hours of playback with ANC off, and up to 44 hours with ANC enabled. When you're in a rush, a quick 5-minute USB-C fast charge provides up to 3 hours of listening time, ensuring your music never has to stop. Connectivity is seamless thanks to Bluetooth 5.3 and Multi-Point Pairing, allowing you to switch effortlessly between two devices, such as a laptop for a Zoom meeting and a smartphone for a call. The dual built-in microphones with VoiceAware ensure your voice remains clear during calls, even in noisy urban settings. Built for mobility, the lightweight on-ear design features cushioned earcups for long-term comfort and a foldable construction that fits easily into a backpack or handbag. For a personalized experience, the JBL Headphones App allows users to customize equalizer settings and manage ANC levels to suit their specific audio preferences.
