If you like the G35's & would like to keep familiar with a Similar setup. I would recommend the G930's which are wireless Variant. Love my pair for gaming and movies.
If your an audiophile, produce music, DJ etc like myself: Sennheiser HD 25 MK II's are the way to go. Love mine to bits and cannot compare them with any other headphones.
