I haven't but, as an opinionated busybody - I might suggest you not try to cancel out ALL sounds. I know there's a lot of people on here that listen to mp3 players as they ride, but be aware, as a new rider you are creating:

1) another distraction - one that will occupy at least a portion of your brain.
2) blocking out other potentially useful information - such as horns, cars in your blind spots engine noise, kids playing, acceleration, braking - even potential transmission/motor/tire feedback from your own bike.
3) you may be tempted to fiddle with the controls enroute - especially if the volume gets too loud or soft, or that guilty pleasure Katy Perry song comes on when you are pulled up next to The Mongeese - a fiddling that has high potential consequences.

You might just want to go with regular good fitting earbuds, but not totally block out the outside world. Riding a motorcycle is a pretty immersive distraction by itself, you may not find it necessary to add additional distraction layers on top.

Also, if you get a good full face helmet (Arai, Shoei, etc.) they don't make much wind noise.
