If you prioritize affordability and portability for use during exercise, the JBL Tune Flex would be a better choice as they are less expensive, have a low latency mode suitable for gaming and exercise, and are also sweatproof. However, if you require headphones with active noise cancelling for air travel, or value overall durability and built-in controls, you might prefer the JBL Live 670NC despite the higher cost. The 670NC offers noise cancellation and is more geared towards comfortable long-term wear for activities such as air travel but is not optimized for exercise and may not be as suitable for gaming due to potential latency issues.

"JBL is offering a similar design and arguably better resolution than the more expensive AirPods 3rd Generation. Add to that a comfortable and versatile fit, an equalizer and pretty decent ANC, and you’ve got a quality wireless earphone. I would have loved longer battery life and more crystal calls, but for the price, you can’t complain. A solid deal overall."
