This week we\'re once again bringing the audio goods to you, and today\'s giveaway should be incredibly tempting. 50 Cent\'s brand, SMS Audio, wants to hook you up with a pair of its premium wireless over-ear headphones, Sync by 50. Priced at $400, these cans are spendier than a fair number of smartphones, but it offers Kleer technology with CD-quality lossless audio and will work up to 50 feet away from your device. And just for kicks and giggles, SMS Audio is also throwing in a snapback hat, shirt and a backpack to go along with your prize, so it\'s definitely worth heading below the rules and leaving a comment to enter. Good luck! The rules: Leave a comment below. Any comment will do. Duplicate entries will be filtered out and discarded, so adding additional comments won\'t increase your likelihood of winning. Contest is open to all residents of the 50 States, the District of Columbia, and Canada (excluding Quebec), 18 or older! Sorry, we don\'t make this rule (we hate excluding anyone), so direct your anger at our lawyers and contest laws if you have to be mad. Winners will be chosen randomly. Two winners will win one (1) pair of Sync by 50 wireless over-ear headphones, one SMS Audio-branded hat, t-shirt and backpack. If you are chosen, you will be notified by email. Winners must respond within three days of being contacted. If you do not respond within that period, another winner will be chosen. This unit is purely for promotional giveaway. SMS Audio, 50 Cent and Engadget / AOL are not held liable to honor warranties or customer service. The full list of rules, in all its legalese glory, can be found here. Entries can be submitted until May 30, 2012 at 11:59PM ET. Good luck!
