Will yet on anything negative to say, is initially very pleased and somewhat impressed. The drives headphones up to 300 ohms and I've even seen people driving lurking at 470 ohms with it and claim it works satisfactorily.
Pulls down rating now from excellent to good. It turns out that you have to connect with the usb to get the real power of it, when you connect the phone with 3.5mm through this so the sound will not be much higher than straight from the phone with the headphones of 250 ohms. This is obviously a disappointment when the app is malfunctioning with the Xperia Z3 so you have to reboot your phone after each time you use it, and unplug it, otherwise you will not Q1. Occasionally frustrating when you have to connect in this way to get all the power you want ... The difference in power is huge if you connect using USB compared with 3.5mm. This makes the whole that I now regret that I did not drive A3 or E12 rather than who has more power. When it works properly is really good but because it seems very whimsical whether it will meet up with your phone when you run the usb so I recommend just buying A3 or E12 if it is only to be used with the phone. Together with the computer, I have not had any problems, really happy there but deduct 2 stars.
