Here's a real bargain if you're looking for on-ear Bluetooth headphones. The JBL E45BT headphones check all the portability boxes: lightweight, nicely padded, and convenient to use. They don't feel quite as durable as some of the higher-end on-ears, but the headband is very flexible and can handle some punishment. (My sample pair survived weeks of getting shoved in and out of bags.) And JBL always delivers a crowd-pleasing sound — they tune every headphone to meet a data-driven sound signature that they've discovered most people prefer.
