AirPod Pro 2 Not staying in my ears !

Have you tried using the different ear tips which come with your AirPods Pro 2? You should try to experiment with the tips provided and find the right one for you. You may need a different-sized ear-tip for each ear.

For example, you may use the small ear-tip for your left ear, but the extra small for your right ear.

Choose your AirPods Pro ear tips and use the Ear Tip Fit Test – Apple Support (UK)

If this doesn't work for you:

• You could try and find third-party ear tips which may provide a better fit
• If you purchased your AirPods Pros recently from Apple, you may be able to return them to Apple. If you purchased them since 8 November, you are able to return them until January 8 2025, under Apple's extended returns window for the holiday season.
