The Logitechs using RF should work nicely and are a quality solution.
One thing, if you play Xbox Live there is no headset port on the controller, it is on the controller's receiver corded to the Xbox (this is common to just about every wireless controller out there not a logi quirk). Some Xbox specific wireless headset options are coming available and some might already be out there. A few people have used a non-xbox specific one from Jabra (non-bluetooth model). You can pick one up from Ebay as retail prices can be quite a bit higher.
