Like @thomsonSMG said, but that's not to say closed-backs can't have a good sound-stage, etc. It's just harder to produce. Closed options are best used on public transport or an office environment, or where you in a room with someone that's a light sleeper. Noise cancelling on the other hand, go a step further and add an "active" part to closed-backs where they try to counter-act surrounding noise by producing an opposing-frequency noise [frequencies in opposing phases at the same time cancel each other out]. This is why they are especially useful in things like air travel, because it's generally one constant noise.

Open back are exactly that. They are not sealed cups, the rear of the driver is exposed to the world and as a result have the ability to sound more natural and part of your environment. Not always though. This can be a positive and a negative. I personally use closed back cans for work in the office and at home when the kids are going nuts (when working from home) and when they are asleep I tend to use open backs on low volume so I dont wake them, but I can hear any action in the house.

Open backs project sound both towards your ears and out the sides of the earpieces. This makes the sound feel as if they are coming from further away. Good for replicating the directions of where each vocals and instruments are coming from; like at a concert. Close backs sound as if the music is coming from the centre of your head; you get less "directional" experience but they feel more intimate. Open backs leak sound so if you are riding on public transport, the people sitting next to you might look at you sideways wonder why you are playing music for everyone around you. Most high end headphones are open back so don't worry about losing any sound quality from the leakage!

They are usually over ear headphones but not always. They allow the speakers to breathe with an open design on the backside. Typically they have a wider soundstage so the music doesn't seem like it's coming from a speaker on your head. Those around you will hear what you're listening to so they are not the best choice for an office environment. They are however the best choice for critical listening at home. Definitely my favorite design.
