Go ahead, try it. The “enthusiastically agreeing head nod” (or its arch nemesis, “the utter-disapproval head shake”). Nope, they’re still in. OK, pretend you’re at a Limp Bizkit concert (circa-1999, of course) and “give it all for the Nookie [come on], the Nookie.” What?!? They’re still in. Now you’ve got to pull out all the stops: do the shake, rattle and roll. Go on, get down on the ground and move it all around. I’ll wait…

Yep, they’re still in.

Yurbuds (super-duper advanced ear buds) simply won’t fall out. Probably because they were developed by a marathoner & triathlete. With patened ear-lock technology, they have a perfect fit even during the most intense workouts. I mean, come on–you can even take a photo of your ear and send it in to them to get fitted. Don’t believe me? Watch this video:

Yurbuds will be giving away 50 of their Ironman series earphones (a $50 value each!) on the Loopt Rewards Wagon. Here’s how to make sure you’re one of the lucky 50:

1. Download Loopt for your iPhone or Android device
2. Check in anywhere in Austin during SXSW, so we know you’re there.
3. Keep Reward Alerts “on” (you can adjust this in Loopt Settings > Notifications).
4. When you get a Reward Alert, launch Loopt to find the prize.
