I got it in an unsealed aluminum container with no usb cable (not sure if I was even supposed to get one, but I have an aftermarket one so it didn't matter much) and I also didn't get the rubber feet pads. Didn't think much of it but when I plugged it into my PC and my HD558s into the E10, no sound came from my headphones. The blue LED lights up but there's no sound at all.
Am I just completely missing something here or should I try to get a refund? This is my first external DAC so don't fault me for any oversights on my part, lol.
