A very interesting observation about the shared public experience of both talking into a phone, vs. the semi-private experience of receiving one half of the conversation in your 'Buds. This echoes at least part of what made talking to people wearing Google Glass so odd - you didn't know what they could see, or where their mind was. In the same way having a conversation with someone while you glance at your phone is rude – because it creates an unevenness of attention – any interaction where you have a private component publicly and visibly involved is going to be awkward.
