If noise cancellation and top-tier comfort for longer sessions, such as air travel and TV watching, are priorities, the Bose Quiet Comfort Ultra Headphones excel with superior build quality and sound. However, their cost is significantly higher. On the other hand, JBL Tune Flex earbuds are more affordable and offer a sweatproof design with a stem form factor, which could be better for exercise. Both support low-latency listening experiences, but the Bose has additional features like a detachable cable and wireless charging, likely justifying their higher price if those features align with your needs.

"The Bose QuietComfort Ultra Headphones are a credible step up from previous Bose ANC headphones, and they're built to hang tough with the competition for years into the future. No waterproofing is a bit of a letdown, but these headphones have the technical chops to make most quite happy."

"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."
