From what I’ve read on various internet forums, it’s much easier to make a good omnidirectional (or non directional) (or just omni) mic than it is to make a good directional mic. And as a result it should be easier to find good, cheap omni mics, which would be great for me, because I love them. They can be placed very close to the source because they don’t have the proximity effect that occurs with directional mics. They seem to capture a big, clear, realistic sound very easily.
The problem has been that there are not a lot of omni mics around. The market doesn’t seem that interested in omnis, so the manufacturers are not interested. In the five years or so that I’ve been recording and buying gear, I would guess that models of directional mics in the marketplace outnumbered omnis by 20 to 1 or more, and almost all the hip new inexpensive mics have been directional.
In the last year or so, though, Jon O’Neil and his Naiant Studio Store has begun selling a very inexpensive omni microphone which Jon builds himself. He use readily available capsules, adds his own active electronics, and mounts the whole thing in an XLR connector shell. The result is compact, rugged, and inexpensive. I think they work pretty well, too. Here’s a brief comparison of a pair of Naiant MSH-1 omnis to a pair of DPA 4061s:
The DPAs carry a list price of $429, and they require an adapter to connect to standard mic preamps that adds about $75 to the cost. Even used they cost about 10 times as much as the Naiant MSH-1 costs new. It’s certainly true that the DPA can be used in more applications, because it’s very small and unobtrusive, and the two different mics are not equivalent, but just on the basis of sound quality, I think they’re amazingly close.
This year Naiant began selling the MSH-2, a mic based on a larger capsule. Jon describes this mic as having lower noise and a gently falling high end compared to the MSH-1. I’m a sucker for an inexpensive omni, so I ordered up a pair. Here’s a recording using one of these new mics alongside an industry standard for microphone quality. I’m using a John Hardy M-1 preamp and Lynx2 converters. This time I set up the Naiant MSH-2 on one channel and a Schoeps CMC6/MK2 on the other. I mounted the mics so they were a few inches apart and about 6 inches from the Martin OM-18GE. Here are the two mono files that resulted:
I can hear some slight differences, although they’re pretty subtle. By turning up the volume and listening to the extended “tail” or decaying signal, I can hear a higher noise level in the Naiant track. But considering that the Schoeps costs about $1400 and the Naiant costs $35, I’d call the similarity pretty amazing. Certainly if someone asked me for an inexpensive microphone to record solo acoustic guitar, I’d be quite comfortable recommending the Naiant MSH-2.

Is there also an very inexpensive way to connect 2 Naiant microphones to a computer?

Jacob, there are a few ways to do this. If your computer has a Line In connector, you can buy a very inexpensive mixer and a couple of cables and adapters. With this arrangement you can get connected for well under $100.
If your computer does not have a Line In connector, and many laptops today do not, then you need some kind of interface device. There are a few that offer 2 mic preamps for under $150 down to $100. Go to any major music retailer like Sweetwater and look for USB interfaces with two mic preamps and 48v phantom power.
Ah, I just noticed that you are in the Netherlands. I’m not sure how to advise you for products that are available in Europe, and I’m afraid you’ll face slightly higher prices.
