If you prioritize noise cancellation and wireless convenience for commuting or flying, the Bose Quiet Comfort Ultra Headphones with superior noise isolation and active noise cancelling are the better option, despite their higher price. For gaming, calls, and meetings, the EPOS PC38X with a high-quality boom mic and excellent sound quality will serve you well, particularly since their open-back design offers a more natural soundstage, but they lack wireless capability and active noise isolation, making them less ideal for noisy environments. The Bose offers lossless codec support and is sweatproof certified for exercise, while the EPOS is better suited for home use given its wired connection and open-back design. Both have a detachable cable, but the Bose provides a wireless option and has a longer battery life, whereas the EPOS is optimized for stationary use with its superb mic quality and sound reproduction.

"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."
