Hi Ozbarginers,
I did some research on the net and here on Ozbargin and this seems reputable and good quality. I want reasonable quality with good bass and this seems like it would.
Where is a reputable place to buy these so that I don't buy 'fake' ones.
This is the cheapest I found: http://www.geekbuying.com/item/Original-Xiaomi-Smartphone-Pi…
I got a set of Xiaomi headphones + powerbank from geekbuying from this deal:

Seems reputable, but shipping times take a while from my experience (and others in the comments).
