Yes, it looks like a quince but before you start cooking them up and serving them for dinner, cut one open - it will look like an apple inside.
If its a quince, they won't be ripe until late fall, when they will turn bright yellow. The riper they get the more perfume-y they smell. They must be cooked to be edible. Quince jelly is one of my favorites. Quince sauce over steam cake or ice cream is pretty awesome too.
