I suggest open back so you get some realistic room ambiance. Closed back cans are great for recording, and provide great isolation, but in a mix, or casual listening situation try these: https://www.amazon.com/Philips-SHP9500S-Precision-Over-Ear-Headphones/dp/B01N3LM3J5

They go on sale every now and then, but they are super comfortable, and sound fantastic. There are lots of choices, and I'd had most of them, like the Sony 7506
https://www.amazon.com/Sony-MDR7506-Professional-Diaphragm-Headphone/dp/B000AJIF4E but they are closed back.
