They just call it the Micro Ring. It's a little easier to say I think.
Great SQ though. If the Monoprice is the $8 standard to go by, these blow past it by quite a bit.
I didn't even realize it, but KZ sent it for free with my order of the 2014 IEM! The Micro Ring I actually ordered is still in transit. Very cool of them :)
where you get them from?
