If you prioritize comfort and want the best noise isolation for air travel, the Bose Quiet Comfort Ultra Headphones offer best-in-class comfort and excellent noise canceling. They're also better suited for TV and gaming due to virtual surround capabilities but do have a higher price point. However, they are not as portable as the earbuds. On the other hand, if you're looking for something more portable and versatile, optimized for use with both Android and Apple devices, the Bowers and Wilkins Pi7 S2 earbuds might appeal to you. They support high-quality audio codecs like AptX HD and Adaptive for better sound quality, and they are sweatproof certified, making them a good option for exercise, but they aren't as comfortable as the Bose for long periods.

Christian Thomas | January 2024
"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."

Billy Steele | March 2023
"While the overall sound quality is great, these earbuds fall short in terms of battery life, customization and ANC performance. Bowers & Wilkins’ ability to consistently deliver pristine sound isn’t enough to make up for what the Pi7 S2 lacks, which is unfortunately quite a bit."
