If budget is a constraint and you're after a pair that costs less, consider the JBL Live 770NC. These over-ear headphones offer good sound quality, comfort, and noise isolation, suitable for air travel and casual music listening. However, they're bulkier and less ideal for exercise. The JBL Live Flex 3 earbuds, although more expensive, are a better fit for active use and provide a secure fit for exercising with excellent portability. Both offer good sound and built-in controls, but for gym-goers or those needing something more compact, the Flex 3 might justify the higher price. Additionally, if having a smart charging case with touch display is appealing, the Flex 3 includes this unique feature. Give Feedback
