I seem to remember a rack of maybe 8-10 headphones in there. Probably leaning toward the higher end. It's been awhile so I can't really recall the brands. - look at the Google photos, one of the first ones is the headphone rack.
Yes, ListenUp has a great selection of headphones. I would recommend calling the store so a salesman can go through the options they have with you
They do have a headphone display as well as some others in a case you can try out. If you are looking for in ear headphones though, they don't have those on display for health reasons, can't have those going in and out of a bunch of ears. If they don't have an exact pair you are looking for in display that they carry, they usually can get a pair in the store for you to try or open some.
