Zone Learn is designed for learning and built for schools. With a comfortable, micro-adjustable fit, audio designed for educational applications, and fully swappable, upgradeable cables and ear pads (1), Zone Learn is built for sustained focus, and long-term use. It's been extensively tested to meet the military standard 810G (4 feet - 1.2 m). Plug-and-Play (1) capabilities include a 3.55 mm AUX, and USB-C, so it works across most devices, operating systems, and conferencing platforms. Zone Learn is made from a minimum of 22% recycled post-consumer materials; 100% PVC-free, VOC-free, and paint-free.
