It's fairly hard to find decent open-cup/open-backed earphones but I managed to hunt down the QH-85 a couple of years ago, as I needed to be able to hear what was going on in the house whilst gaming (listen out for baby at night time). Have to say these are brilliant - great sound, a fully flexible and detachable mic and a range of cables included too. I've been very happy with them. I do find them a bit uncomfortable after a couple of hours but I so rarely get to game for that long these days that it isn't an issue. They feel strong too.
For reference, I was coming from the Asus Vulcan, which was excellent but as I say I needed open cups. I'd put them on a par with each other but they serve different purposes.
