Is beats flex supports Dolby atmos on apple music? How can I test it?

Hello Mohsenfarahmand,

We understand that you're interested in Dolby Atmos with Apple Music through your Beats Flex. Per the below article, "By default, Apple Music will automatically play Dolby Atmos tracks on all AirPods and Beats headphones with an H1 or W1 chip, as well as the built-in speakers in the latest versions of iPhone, iPad, and Mac."

Apple Music announces Spatial Audio with Dolby Atmos - Apple Support

Per Beats Flex - Wireless Earphones - Beats, the Beats Flex contains the W1 chip. So it would be compatible with Dolby Atmos.

Thanks for using Apple Support Communities!
