So I contacted FiiO customer service about possibly getting a refund for the E10 because of the popping issues that I (and YYZ88) described above, but they said that the only option would be to send it in for a repair. I said alright and checked it out with shipping companies and found that sending it to China would end up costing more than what I paid for the thing originally, so I said no thanks. They came back and said they'd send an E07K too for my troubles if I sent the E10 back for repairs. I don't really have much use for it though, so I decided to just move on from FiiO. I ordered the Schiit Magni/Modi combo to replace the E10.
I can't knock FiiO customer service because they're doing what they can under the circumstances of crappy quality control, but I still don't want to have much to do with them for that same reason. Their products are great performers for the price... when they work. But when they don't, the fact that they're in China and are likely only offering those low prices because of their economy of scale and lack of quality control, it's just not worth the risk imo.
That is all. Not dealing wif it.
EDIT: Made a post on the next page chronicling the process of their eventually offering me a new E10 free of charge. I didn't even ask for one, but I won't say no.
