AirPods, particularly in transparency mode, offer an interesting approach to augmented reality. However, to truly enhance their utility, it would be beneficial if there was an external indicator to show whether or not they are in use (maybe a LED?). This would allow others to know if they can initiate a conversation. In the past, the sight of someone wearing headphones was a clear signal not to disturb them, but with the prevalence of AirPods today, that dynamic has shifted. On the other hand, bone-conducting headphones like Sentien don't face this issue, as they don't block the ear canal, ensuring the user is always ready to listen.
