I ordered some Comply's a week ago and they just came in today. Not really impressed with them though, they seal well and are comfortable but they do take a bit away from the highs. It's a subtle change, but I prefer the sound of the foam Supertips the best. Bass doesn't seem to be affected much. If I'm just going to be sitting around in the office I think the Supertips would be my choice, but if I were on a 6 hour flight I would go with the Comply's. The main issue I have with the Comply's is that they don't fit tight to the nozzle of the MTPC and keep sticking in my ear canal when I try to take my earphones out. Maybe I just got a bad batch.
Keep in mind this is only for Comply + MTPC combo. I also got some for my MEE M6 and those ones work great and are quite an improvement over the stock tips.
