No.. These are not omnis... These look like the WM-55 series panasonic caps... which also have similer specs. With the connector and the p48 circuit... you can't do better.
I guess I forgot about the circuitry, though I have to plead ignorance on what it does between the mic and the battery box/recording device to improve the sound. I was under the impression that most of the capsules (at least the ones that can run on phantom power) had all the necessary circuitry inside the capsule...? Again, I only know what my own experience has taught me, though I know it's a pretty common mod to remove or bypass the circuitry in the stock capsules to substitute your own, I've never gone that far myself.
