This little DAC produces better sound quality than products costing two to three times as much. Its almost like having a desktop audio system shrunk down to a tiny Gizmo that fits in your pocket. The best part of this product is the DAC, not the amp, so it sounds even better if you pair it with a good dedicated headphone amp... Especially if your headphones are hard to drive. The Dragonfly Red is capable of driving up to 300 ohm headphones, but not necessarily as well as a dedicated headphone amp would.
