The JBL Tune 670NC wireless on-ear headphones in a sleek Black finish provide a versatile listening experience centered around the signature Pure Bass Sound. These headphones utilize 32 mm drivers to deliver audio across a frequency range of 20 Hz to 20 kHz, while the adaptive noise cancelling technology helps you stay focused by reducing unwanted environmental sounds. When you need to stay alert or have a quick conversation, the Ambient Aware and TalkThru features allow you to hear your surroundings without removing the device from your ears. Designed for long-term use, the lightweight 174 g Black frame features a flat-folding design that makes them easy to tuck into a bag for travel. You can rely on a substantial battery life that lasts up to 70 hours with noise cancelling turned off, or up to 44 hours when it is active, with a full recharge taking about 2 hours via the USB Type-C port. Bluetooth 5.3 ensures a stable connection within a 10-meter range and supports multipoint connectivity, letting you switch seamlessly between two paired devices. For those who prefer a tailored sound, the JBL Headphones App allows you to customize the EQ and EQ settings, and manage the Smart Audio & Video mode. The headphones also support hands-free calls through Voice Aware and include a 3.5 mm audio jack for wired listening when the battery runs low. Each pair comes with a detachable audio cable and a charging cable to ensure you have everything needed to get started.
