Our Verdict

Anker SoundCore Spirit X Wireless

Anker SoundBuds Curve 2019

The Anker SoundBuds Curve 2019 are marginally better headphones than the Anker SoundCore Spirit X Wireless. The SoundBuds look and feel almost identical and have very similar sound profiles, but the Curve have a much longer battery life, and their treble range is slightly more accurate.
