how much does the odeon fit?

Thank you all so much-very helpful and I was able to make the decision to buy the Odeon tomorrow because of your help!!!
I usually don't carry much stuff in my bag but here it is. I could fit these items in the Odeon. I personally wouldn't pack a pouch because I don't like the bag to be too heavy.

iPhone 5S and 6 key folder were placed in the front pocket. The headphone and the card case are stored in the two inside pockets.
i have both and they fit just about the same amount. odeon is thicker but bloomsbury has the pleat. great bags.
