SMS Audio (Studio Mastered Sound) allows you to experience the power of music on your own terms. These devices provide you with an escape into the lush work of professionally tuned, acoustically perfect music… Anywhere, anytime and any way you want to hear it.

Exceptional sound quality, style & durability, SMS Audio has created a world-class headphone like no other. Combining technology, function and style to bring you the highest caliber sound, comfort and fashion to every product.

Introducing 50 Cent as majority owner to the brand, 50 Cent had no intention of becoming another rapper with a headphone and instead of just slapping his name on a product, helped to engineer a line “SYNC by 50 Cent” & “STREET by 50 Cent” to compete at the highest level with our other brands in stores today. Through his involvement with product development, style and sound of each product, 50 Cent has brought something new to the industry, designing some of the most true to sound audio producing products on the market today.
