You can try memory foam tips (like Comply). This seems to help me whenever I encounter IEMs with extreme driver flex that can't be tamed any other way. I own the 3.14 microdriver IEMs. It's basically the same form factor as the MR3's but with a single microdriver instead of 3 way BA configuration. I must say that all 3.14 models are tuned the same, sound the same and suck the same. At least this is the conclusion I reached from my discussions with another member of head-fi that purchased the 3.14 BA models.
