If you prioritize noise cancellation, comfort for longer wearing, better sound isolation for air travel, and don't mind paying more, the JBL Live 770NC is ideal for you. They are over-ear headphones with active noise cancelling that work well in noisy environments. However, these may not be suitable for workouts due to their size and weight. In contrast, if you're on a budget, prefer something for gaming due to low latency mode, need earbuds that are sweatproof, and want a more portable option, the JBL Tune Flex could be the better choice for you. Keep in mind, the Tune Flex lacks the same level of comfort and noise isolation for air travel compared to the 770NC. Give Feedback

"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."
