I just posted my "for sale" article in the Yard Sale for a Neumann carrying case. This was designed for pairs of their U 87, U 89, TLM 103, TLM 127 (does anyone here use those?), TLM 170 and possibly other models. The case is designed with two cutout areas in the foam, into which you would place a pair of their inserts that are tailored for the specific microphone type.
I no longer seem to have any of those inserts, so on Monday I'll find out what Neumann USA has available and what they cost. Or you could fill in the space with your own padding, of course.
