When in transparency mode, will others hear sound?

Hello Robert Campbell1,

Welcome to Apple Support Communities. We understand you have a question about using Transparency mode with your AirPods Pro (1st generation). Generally, Transparency mode lets outside sound in, so you can hear what's going on around you. Active Noise Cancellation and Transparency mode work best when your AirPods Pro fit properly. Others should not hear what you have playing, but it is a good idea to do the Ear Tip Fit Test if it seems like that is occurring.

Choose your AirPods Pro ear tips and use the Ear Tip Fit Test - Apple Support

You can also customized Transparency mode for it to work better for you, depending on your surroundings and what you want to be able to hear around you. Use the following guide:

Feel free to reply back with any additional concerns.

Take care.

Hi Robert,

Using third party tips may affect Transparency Mode and Active Noise Cancellation. You'd have to test to see if they would work well for you.

Take care.
