My only goal is to connect a Dragonfly DAC/headphone amp to my phone and this device does the job perfectly. I can even charge my phone while listening to music. This special box is more expensive than another adapter that only has a USB port (no charging function). However, it doesn't generate the pops and clicks reported by other users with a cheaper model, and the ability to charge at the same time justifies the extra cost. I would recommend this device.
