USB Dongle DACs are taking off, and companies like HRT are attempting to combine small form factor with features and sound quality. Unlike Audioquest's Dragonfly, the microStreamer sports two output jacks, one fixed and optimized for line level destinations and the other with variable out for headphones.

The microStreamer will retail for $189.95, can handle streams up to 24/96 and is connected to your computer or source with a short USB cable. The company explains that this approach prevents mishaps where the dongle could damage your computer's USB connector if it was plugged straight in like the Dragonfly.
