Generally open box means someone bought it and returned it, but not because it was defective. The item was possibly used for a short period of time, depending on the seller's or the store's return policy. So more of a trial than heavy duty usage.
Pre-owned - a term I strongly dislike since 'used' is more precise - means an item has been used but still works as intended. You do not usually know how long the item has been in use.
