We ordered a 7 for our son, who wears a 9 and they are easily still an inch or more too big. The ear pads are very comfortable and easy to install however I notice the noise canceling did not work as well using the OEM bose ear pads. If I had to choose between a wired G502 and this mouse I would pick this one because the wireless makes my desktop feel a bit cleaner and not so cluttered, but if you want something that has a tighter more solid build go with the G502 Hero. Wears out too fast and thin soles. One day delivery! I have two different heights. Supper happy with the purchase. Stopped working after using 6 times. This would be a great unit if it worked as advertised. Ordered a pair of these headphones.
