If you prioritize portability and use during exercise, the JBL Live Flex 3 earbuds would be the better choice; they are designed for an active lifestyle with sweatproof certification. However, if you're seeking superior noise isolation, particularly for air travel, and don't mind a larger form factor, the Soundcore Space One headphones may suit you better. The JBLs offer a unique Smart Charging Case with an LED touch display, which could appeal to tech enthusiasts, whereas the Soundcores provide a foldable design for easy storage. Note, the JBLs are pricier, so if cost is a concern, the Soundcores offer good build quality and battery life at a lower midrange price. Give Feedback

PC Magazine
Tim Gideon | September 2023
"The Anker Soundcore Space One noise-cancelling headphones are stylish, comfortable, and affordable. They offer better active noise cancellation than we expect for the price, and their sculpted audio impresses thanks to the adjustable EQ and support for the hi-res LDAC codec. Overall, they’re an excellent value and well worth your attention if you're on a budget."
