If affordability is a priority, the JBL Live 670NC are a better choice as they are often significantly less expensive than the JBL Live Flex 3. The JBL Live 670NC headphones offer active noise cancelling, are comfortable for air travel, and have a longer battery life, making them suitable for extended use in noisy environments. However, they do not perform well for gaming or TV watching due to poor sound quality in those contexts. For exercise enthusiasts or those looking for better portability and sweatproof features, the JBL Live Flex 3 earbuds are the go-to option, though their higher price and shorter battery life may be a tradeoff. Additionally, the JBL Live Flex 3, with their smart charging case featuring an LED touch display, provide a more technologically advanced experience albeit at a premium price point. Give Feedback
