Our Verdict

Anker SoundBuds Curve 2019

Beats Flex Wireless

The Anker SoundBuds Curve 2019 and the Beats Flex Wireless offer similar performances, and you may prefer one over the other. The Anker come with a hard case and are more stable. They also have a better-balanced sound profile and a longer-lasting continuous battery life. However, the Beats feel better built and have a W1 chip, so you can seamlessly pair them with Apple devices.
