Thank you for your suggestions, Petrus! I read good reviews on the MK-012, so maybe I will buy these!
The MTII might also be used for stealth recordings, or for catching some outdoor sounds on one of my trips with the binaurals I once bought from Sound Professionals (SP-TFB-2). Furthermore: I don't have a laptop, alas.
Does anyone have any experience with the new SE Electronics SE 4 matched pair? They have the same price as the MK-12 MSP6, and the same characteristics as the SE3, and have also matched pairs of capsules for omni, cardioid and hypercardioid. I don't know if I would ever use the hyper-cardioid ones, but it would be nice to experiment with omni's and cardioids.
