On the Creative Labs hold down the button until you hear the tones and keep holding until a voice says "Now in Pairing Mode". Then turn on your Nox. The first time hold down the the wireless button on the Nox for 5 seconds until you hear the reset tone. Now it will try to pair, I've seen this take up to 2 minutes. After the first pairing they sync by the end of the Nox boot up tones.
The Creative Labs fit loose so you can hear around you and have a fairly loud volume. Awesome in this awful heat.
