What's your use case here? are you looking for something to make calls with, or listen to music? Will you be sat in a chair/on the bus/train, or running/jogging/etc. with them?

You've asked for an earpiece, but do you specifically mean one of the mono earpieces that sit on your ear for when you need them, or are you open to buds, headphones, etc.?
