Pick the Momentum 4 Wireless if your top frustration with your current device is running out of charge before the day ends — endurance is the lead spec here. The biggest gaps in its favor are battery life, driver size, ldac.
Pick the WH-CH720N if you carry the device everywhere and weight or thickness has been the deciding factor before. Its strongest claims are weight.
