The JBL Live 770NC are over-ear headphones designed to provide a balanced listening experience through JBL Signature Sound and Spatial Sound. They feature True Adaptive Noise Cancelling, which works alongside Smart Ambient, Ambient Aware, and Talk Thru technologies to let you control how much of the outside world you hear. You can further customize your audio profile using Personi-Fi 2.0 via the JBL Headphones app, where you can also adjust the EQ and noise cancellation settings. Equipped with 40 mm drivers and Bluetooth 5.3, these headphones support multi-point connection so you can switch between two devices seamlessly within a 10-meter range. For those who prefer a wired connection or need to expand the frequency response up to 40 kHz, a detachable 3.5 mm audio cable is included. The build is lightweight at 256 g, making them comfortable for extended wear during long commutes or work sessions. Battery life is a standout feature, offering up to 65 hours of playback with noise cancelling off and 50 hours when it is active. If you are in a rush, a quick five-minute charge provides about four hours of listening time. The package comes complete with a carrying case and USB Type-C charging cable, making them a practical choice for anyone who needs reliable wireless audio for daily use.
