Review on xDuoo Accessory XP-2 Portable Bluetooth and USB DAC Headphone Amplifier - Black by Jennifer Norris

This is a fantastic device. Decent range despite mostly metal body, good performance with this gain switch. One of the best volume controls on a portable device. But in the end I couldn't give it 5 stars because it lacks the basic bluetooth boost function to pause and change tracks. This together should achieve almost 3 stars. If you use this in your pocket and your phone in your hands, you can get away with it. BUT, if you plug in your phone and interact solely with that device, you'd better never pause or skip tracks. Still sounds too good for 3 stars.
