The product is good, the only problem is that there's a delay in the audio reproduction of new files, tried fixing it with the buffer settings but it seems it's not related to that (since the audio actually shows like playing, it's just the sound that doesn't sound) this happens at the first 0,6 seconds of any audio that you start playing from 0. (so it's not a problem in movies or games, but it's very annoying in music reproduction since when the track changes you always lose the first second of the intro)

Very fast shipping to Switzerland, unpacked, but it was not working. Turned out to be a failure in the power adaptor. Once working with another item,amazing sound, volume and quality for this price. Recommended!

Arrived in about one week upon ordering. Package was fine and goods unharmed. Works very well with my higher impedance AKG K601 headphones with USB connection to desktop PC. Plenty of power to spare and clear sound.
