If you prioritize sound for diverse activities like music and exercise, the JBL Live Flex 3 might be the better choice with its very good overall sound quality and suitability for use during exercise, along with impressive battery life and a unique Smart Charging Case with a touch display for control. However, if you need earbuds that perform well for calls and meetings, neither excels in this area. The JBL's distinct feature for sound control on the case and longer battery may justify its higher price. Conversely, if you're looking for something lighter and prefer a closed, stemless design for better noise isolation and a more snug fit, which may be better for quieter environments, the Sennheiser Momentum True Wireless 2 might be more suitable, albeit with a trade-off in battery life and lacking the special charging case features of the JBL.

What HiFi? | November 2022
"They are more comfortable and nicer to use than their predecessors, battery life is better and noise-cancelling is now included as part of the package. They’re easy to live with and you could happily listen to them for hours on end without reaching for the pause button. If your budget allows, your ears will be handsomely rewarded."
