In reply to Anhub:
I like JBL reflect mini 2 (if you can still get them), but only the ones which have a cable between earpieces and buttons to press. Decent sound, long life, and don't fall out of your ears at all.
I tried a set of the newer model which are just ear buds with tap to touch "buttons". These are useless for running, as the "buttons" just don't work well, and you can't even switch them on or off without the case. Something to bear in mind for ear buds only?
Was unable to find the JBL reflect mini 2 (but you may be able to in the UK), so ordered the Endurance Run BT which seems to be the closest equivalent available, but haven't tried them yet.
