Good-sounding mic. No question about that! It would have been a winner for me, if it wasn't for two disappointing factors:
1. The foam in the head basket lacked a 1x1 cm chunk, leaving part of the basket uncovered (on the inside). I didn't purchase it as a B-stock item, it should be brand new, so I can only assume it was due to lacking/poor quality control on Lewitt's part. It leaves a bad first impression. This isn't a cheap mic.
2. The polar patterns... Either the polar pattern switch doesn't work, or the patterns are so similar the mic could just as well have been a regular one-pattern cardioid.
I've tested the patterns in all ways imaginable: with and without the basket mounted, with white noise, with speech, recorded it and analyzed with frequency analyzers, null-points of the super cardioid vs the cardioid mode, and on and on. The result remains the same: I can't hear any significant change between the polar patterns.
I also tested its feedback rejection extensively, and there wasn't any difference between the "polar patterns" there, either.
If there is a very very minimal difference, it's so minimal that it feels like a 0.3-0.5 db difference here and there... MAYBE. Could also just be an imaginative change.
With all that said, the mic sounds very good. Like a good LDC. Very low noise floor. It has a tad more presence (3-7 KHz) than most other condensers – without shrillness / harshness. If its polar patterns worked, I'd have kept it. But I didn't buy this mic for it to be a cardioid mic. I got it because I wanted a mic that could switch between super cardioid and wide cardioid. As it stands, the only thing I got from it, felt like a cardioid, no matter what the switch was set to.
I wrote Lewitt about the above issues, and received a forthcoming, very helpful reply, offering me apologies + to send me a new basket. They also confirmed that the patterns in this mic are indeed very close/similar. My correspondence with Lewitt's headquarters left me with a very positive, warmhearted impression. They genuinely care about their customers, and show lots of respect and decency. So I may try another Lewitt mic at some point:)
The mic I received might've been faulty. I'll probably never know, as I decided to return it (thanks Thomann!)
I may get a Shure KSM9HS (similar dual-diaphragm concept) as a replacement. It has higher self-noise and lower sensitivity than the Lewitt mic, though. So I'm not... Shure :)
