PROS
Amazing full range noise isolation performance. Comfortable and well-built design.

CONS
They lack stability fins and can pop out of your ear.

The Anker Space A40 are fair for neutral sound. Their warm sound profile brings a cozy feel to vocals and instruments in your favorite tunes. Out-of-the-box, they lack some low-bass, though, and their underemphasized treble veils details in the mix. Thanks to the graphic EQ and presets in their companion app, you can switch up their sound. Of course, as in-ear headphones, their soundstage isn't the most immersive.

PROS
Sound customization features available via companion app.

CONS
Bad passive soundstage.

The Anker Space A40 are great for commuting and travel. Thanks to their adaptive ANC system, these headphones can block out background noises like bus and plane engines. They boast a comfortable fit and a portable design that's easy to take with you on the go. Plus, they last over eight hours continuously, and their carrying case supplies an extra four charges if you need it.

The Anker Space A40 are great for sports and fitness. They're comfortable enough for long workouts and sturdy enough to withstand wear and tear. If you like to exercise outdoors, there's even an IPX4 rating for water resistance to help protect them against the elements. They'll stay in your ears for more moderate workouts, but since they lack stability fins, their fit isn't quite as secure as some other models.

The Anker Space A40 are good for office use. With a continuous battery life of over eight hours, they last through most work days, and their carrying case offers some extra charges if you need to top them up. You can pair these headphones to up to two devices at a time, making it easy to switch between your phone and your laptop. Also, their adaptive ANC system helps you focus on your work by reducing ambient noise, like the chatter of nearby coworkers.

PROS

PROS
Supports multi-device pairing.

CONS
Mic has poor recording quality.

The Anker Space A40 are truly wireless headphones. While you can connect them to Bluetooth-enabled PCs, their latency is likely too high to be suitable for gaming, even when using their low-latency 'Game Mode'.

The Anker Space A40 are Bluetooth-only headphones; you can't use them wired.

The Anker Space A40 are passable for phone calls. Their integrated mic has poor recording quality, so your voice sounds distant and sibilant to whoever's on the other end of the line. The mic can separate your voice from moderate background noise, but it's no match for louder environments like a busy street. You'll want to take your calls in quieter places if possible.

PROS
Amazing full range noise isolation performance.

CONS
Mic has poor recording quality.
