To each their own. I think you can disclose it and do just fine, especially for one interview and the confidence to get through it. Just because it’s an AirPod doesn’t mean it doesn’t have practical uses. Sometimes a “crutch” is helpful in a high stress situation with limited time to improve. I’ve worked as a teacher for 12 years, and I use it for parent nights and speaking in front of large crowds of peers for presentation purposes. I always tell them what it’s for and never had someone view me as “unprofessional”. People use AirPods for hearing amplification, language clarification, etc. so I disagree it’s a bad look.
