Why my beats flex always got disconnect while I listen?

Hi ChalyBeatsFlex,

Thanks for reaching out to Apple Support Communities. It sounds like you're having an issue with keeping your Beats Flex connected to your iPhone. We're happy to provide some information to assist.

We recommend starting with the steps in the article here: If you can't connect to your wireless Beats product

This includes a reset of your Beats Flex to test. If needed, you can find those steps here: Reset your Beats earphones

If this only occurs with your iPhone, test a normal restart. Restart your iPhone

Should the issue continue, reach out to Apple Support directly to further assist.

Cheers!
