Why is the left side of my beats studio 3 wireless intermittently stopping and working when I move my head?

Hi Sékou,

Thanks for visiting the Apple Support Communities. It looks like you are having some trouble with the left side of your Beats. 

That’s a good article shared with your post for troubleshooting sound. Does this happen with all devices you pair your Beats with? 

You can try resetting your Beats. The steps for this can be found here, Reset your Beats on-ear or over-ear headphones. 

If that doesn’t work, you are going to want to reach out to Apple Support. They can be reached at Get Support.

Good luck!
