Choosing between the Bose Quiet Comfort Ultra Headphones and Soundcore Space A40 depends on your priorities. If you want exceptional comfort, noise cancellation for travel, and high-quality sound for TV and gaming, and are willing to pay a premium, the Bose headphones are a better choice. However, if you prefer something more portable, significantly cheaper, and with a longer battery life that's suitable for exercise, the Soundcore Space A40 would be more appropriate despite its limited performance for calls, meetings, and gaming. Keep in mind, the Bose has a detachable cable and offers lossless audio support, while the Soundcore provides a more discreet earbud form factor with wireless charging. Give Feedback

"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."

"The Anker Soundcore Space A40 is an excellent deal if you want affordable noise canceling earbuds with great sound. The baseline frequency response is enjoyable, and the many EQ presets to choose from plus the ability to customize your sound profile makes it good for pretty much anyone. The noise canceling is quite good, and the many ear tips to choose from ensure a good fit for the noise canceling and isolation to do its job."
