The unit came partially charged, and plugging it in with the included micro USB to USB cable triggered an automatic driver install in Windows. You can then select the DAC as the audio output in the Volume Mixer.
The build quality (especially metal body) is pretty impressive for the price, although the power switch and volume dial do have a little wobble to them.
Another thing I like about this is that it is built very well, everything feels solid and I don't worry about this breaking anytime soon. It's very sleek and small and doesn't make your phone too bulky. The volume control and ports are placed nicely as well.
The battery life is rediculously good. I couldn't believe how long this thing lasts! Also I thought the price for this was very good for what you get.
I would have liked to have seen better cables however. The mini aux cable that comes with it is very cheap and doesn't work very well.
Slim case provides portability
Works great on my PC
Nice addition to my Ultrasone Pro 550 providing a plenty of headroom for the sound and kick
Although I don't get to use it everyday, it does its job very well whenever I put it to a task. $50 well spent.
Get some low level hum w/o music to cover it up. Does provide better range separation at listening levels
Gives the amp boost I wanted for listening while motorcycling.
I m trying to run down battery from factory charge -- still going with 8+ hrs!
