Hello MiongJ.
Thanks for reaching out to Apple Support Communities. We see that you would like to know if PowersBeats are compatible with Dolby Atmos in Apple Music. We will be glad to assist. According to this article, Dolby Atmos works with any headphones: Apple Music
"All Apple Music subscribers using the latest version of Apple Music on iPhone, iPad, Mac, and Apple TV can listen to thousands of Dolby Atmos music tracks using any headphones. When you listen with compatible Apple or Beats headphones, Dolby Atmos music plays back automatically when available for a song. For other headphones, go to Settings > Music > Audio and set Dolby Atmos to Always On."
Only using Automatic playback in Dolby requires the specific requirements you're referring to.
Cheers.
