From music to calls, the active noise-cancelling on these JBL headphones keeps you fully immersed. Its 4 mics cut down noise until you hit the Smart Ambient button. Then everything comes flooding back in, so you can hear your surroundings. If you're streaming or gaming, you'll feel smack bang in the middle of the action too. The 40 mm drivers dish out booming bass and JBL Spatial Sound even gives you virtual surround.
