If you prioritize comfort and noise isolation for long flights, the Bose Quiet Comfort 45 headphones with their over-ear design might be the better choice as they're highly rated for both air travel and noise isolation. They also have a premium build quality, an integrated microphone, and are foldable for easier portability. Conversely, the Soundcore Space A40 earbuds are a more affordable option, with a compact size that's good for portability and exercise, offering features like wireless charging and a longer battery life which might be beneficial for daily use. However, for immersive listening experiences during calls, meetings, or use with gaming and TV, the Bose may have an advantage in mic quality and comfort, albeit at a higher price point. Both options have active noise cancelling and are well-suited for a variety of audio content, so your decision could hinge on whether you value portability and price over superior comfort and isolation.

"If you want a set of wireless over-ear headphones you can put on, deploy noise-cancelling on your commute or at your desk and largely extinguish the outside world for up to 24 hours, the Bose QC 45 has the edge over most of the competition at the price."

Sam Smart | May 2023
"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."
