JBL Live 670NC Wireless On-ear Headphones, Sandstone

The JBL Live 670NC is a set of wireless on-ear headphones equipped with 40 mm dynamic drivers that produce a frequency response of 20 Hz to 20,000 Hz. They connect to devices primarily through Bluetooth 5.3, supporting HFP, A2DP, and AVRCP profiles for broad compatibility. For situations where a wired connection is preferred or required, a detachable 3.5 mm audio cable is included. The design features a closed-back acoustic system, a textured fabric headband, and soft ear cushions intended for extended listening sessions.

These headphones incorporate True Adaptive Noise Cancelling to reduce ambient sounds, which can be managed alongside other settings via the JBL Headphones app. The dual built-in microphones are designed to provide clarity for calls. Battery performance provides up to 50 hours of playback with noise-canceling engaged and extends to 65 hours when turned off. A fast-charging function delivers additional playback time from a five-minute charge via the USB-C port, while a full recharge takes approximately two hours. The unit weighs 219 grams and is foldable for storage in the supplied carrying case.
