The tips are called Mandarin, I think, and they came from Hungary. One of the ME.1 reviews I read suggested them. The 'wide bore' is a perfect fit. You gotta order on EBay and the shipping from Europe takes a while to US. They're great! Foam is protected so they don't rip!
As far as sound, you gotta amp with headphone power. They shine, baby! Full output from DAP plus a little gain from amp! ME.1 is like HE-6! Push'em!
If they are the ones I was looking at, they are the Symbio W (made by Mandarin). I have read a lot of good things about them.
