Exertis Connect USB External Sound Card 921550

This USB sound card adds a 3.5mm headphone jack and a 3.5mm microphone jack through a single USB-A connection, giving computers without audio ports a simple way to connect headsets or speakers. Unlike internal sound cards, it requires no opening of the case and no driver installation.
