Very nice and smooth upper-mid registry, even more so than the TLM103 I think. As the cheapest LDC mic Neumann has to offer, I think every professional mic collection should have 2 of these for all-around instrument/vocal use.
Small and sturdy enough to be used live as well as in studio setups. As a fixed cardioid pattern mic the off-axis sound leaves something to be desired, but the on-axis sound is a LOT bang for the buck when you know where to use it. The (plastic?) fixing ring seems it could break at some point, but even the older ones I have been going great.
I use these for drum over/underheads, choir vocals, lead/bg vocals when recording, also works as an acoustic guitar mic since the upper mids are so smooth. Maybe not for a super bright Taylor etc. because of the lower resonance freq most LDC's have.
Great all-around condenser!
