The JBL LIVE 670NC is a pair of closed over-ear headphones designed for those who want a versatile audio experience throughout their day. These headphones feature True Adaptive Noise Cancelling, which helps you stay focused by adjusting to your environment, and support JBL Spatial Sound and Hi-Res Audio for a more immersive listening experience. They are powered by dynamic drivers with a frequency response of 20 Hz to 20,000 Hz and a sensitivity of 98 dB SPL/mW, ensuring a balanced sound profile across different genres. Connectivity is handled via Bluetooth 5.3, allowing for a stable wireless link and multipoint connection so you can switch between two devices effortlessly. If the battery runs low or you prefer a wired setup, you can use the included 1.2 m detachable 3.5 mm audio cable. The battery life is particularly impressive, offering up to 65 hours of playback on a single charge, with a full recharge taking about 3 hours via the USB Type-C port. Weighing only 219 g, these headphones in a sand finish are light enough for extended wear during commutes or long work sessions. Two integrated microphones allow for clear voice calls and interaction with your preferred voice assistant. The package comes complete with the headphones, a charging cable, and the analog audio cable, making them ready for use right out of the box.
