50 Cent demonstrated his SMS Audio headphones, explaining that improving the quality of sound for listeners is an extension of his passion for music. “This is an opportunity for people to hear [music] the way it was intended to be heard,” said 50. Another bonus to SYNC and STREET, which range in price from $249 to $399: they’re wireless and can transmit sound from a device up to 50 feet away.

Fallon, meanwhile, performed songs from his album, including his trademark Neil Young-esque rendition of the “The Fresh Prince of Bel-Air” theme song and a Bob Dylan-inspired taken on the “Charles in Charge” theme. Fallon also plugged his second book, Thank You Notes 2, which recently topped the New York Times bestseller list.

“It’s not uncommon to see celebrities on air at QVC,” said Doug Rose, senior vice president of QVC programming and marketing, “but it is rare when two guests with such star power are featured on the same broadcast.”
