Having had both I would suggest the G930. Its very comfortable, light, great quality and the wireless is awesome. The 1500 is maybe more comfortable though (fluffy pads) but the quality is not as good and I also had a slight buzz in one of the ears in mine which was annoying and led me to get rid of them.
A little odd to compare both though as would not the Corsair 2000 be better if you are going for wireless and also more comparable on price, although I have not tried them.
