If you prioritize active noise cancelling and better sound quality during calls, the JBL Live 670NC headphones are suitable, especially for air travel and listening in noisy environments, but they're bulkier if portability is a concern. However, if budget and portability are key factors, and you enjoy longer battery life with the convenience of wireless charging, Soundcore Space A40 earbuds are a more cost-effective choice. The Space A40s also offer LDAC support for high-quality audio streaming, making them better for music enthusiasts, but they lack noise cancelling, which means they won't block out ambient noise as effectively as the JBLs.

"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."
