This is a great unit for the price, see pros to the side.  The only cons are the headphone amp whilst good will leave you wanting to upgrade this section later down the line (which this unit allows you to use the dac and send the signal to an external amp in any case), and the lack of power switch on the front will annoy some.

I have used this headphones on many and whilst they are very comftorable and look quite nice, the audio quality is extremely poor and they are not very sturdy.  My best description as vulgar as it may or may not be is that they are poo, very comtorable poo.
