Our Verdict

Beats BeatsX Wireless

Beats Flex Wireless

The Beats Flex Wireless are better in-ears for most uses than the Beats BeatsX Wireless. The Flex are more comfortable, feel better built, and have a longer continuous battery life. They also have lower audio latency on iOS and Android. However, the BeatsX are more stable in-ear come with a case. They also have a better-balanced sound profile with less bass boost, which may be a better choice if you don't listen to a lot of hip-hop or EDM.
