Listening to music via my mobile often enough, I was tired of having to change my phone to have a sound and proper volume. After reading several test I threw myself into buying this amp. On robust and well finished appearance, the product inspires confidence. And finally it is turned on and try it. I am the User with Turbine Pro Copper Monster (ITE good for my taste) coupled either to my Nexus 5 is in my cowon J3, and I rediscovered! A more dynamic sound and Detailed, low tauter and more acceptable volume (although never pushing very hard). I do not think the difference in quality would be so remarkable that my thinking had to be easy to ITE driver, but I am totally amazed!
