Hi again, Dave! Thank you for reaching out, and we are sorry to hear that your AirPods 4 are not staying securely in your ears. We know how important a comfortable and reliable fit is for enjoying your audio, and we understand your frustration with this situation. Since fit challenges are typically a matter of individual ear anatomy and device design, we recommend contacting Apple Support directly or visiting an Apple Store. Their team can provide specialized fit tips, discuss potential adjustment solutions, or check for alternative options that might work better for you.
