Straight answer Larry, they shouldn't. I have a "matched" pair of NT5's too, & they're the same (or at least, within the scope of my hearing ability).Are matched pairs of microphones meant to be 1 brighter and 1 darker, or both equal in response, or something else? I have a matched pair of Rode NT5's and they both sound different when plugged into the same cable.
Agreed. I love NT5's for their lack of pretension & workmanlike approach, but compared to the high end stuff, they're fairly limited. I use NT5's on most gigs without issues.Agreed with all the responses here. Regrettably with things like mics you do really get what you pay for.
