The image of the Buddha wearing headphones are sensitive to the mass majority of Buddhists. For the Myanmese especially since this happened in Rangoon. Majority of Buddhist do have a fix image of the Buddha and anything our of this expectation just won't do.
But what is the Ananda requested the Buddha to live another kalpa, and he is still alive today? Don't you think the Buddha would be wearing a headphone at some point? Would that be ok or do we tell the Buddha He is wrong to wear a headphone and that is not what we expect him to do?
So, it is not the Buddha's image that is the practice. It is the expectations that we have that is bringing the suffering. However, that being the case, since majority of Buddhist have expectations even on the Buddha, we should respect that.
