CAD Audio U37 USB Condenser Microphone (Discontinued)
The CAD Audio U37 USB is a very affordable USB condenser mic which allows for direct audio recording via USB cable.
There's a nifty 10dB overload-protection switch and a nifty bass-reduction switch that allows for handling high SPL sources. The built-in pad can also be used to reduce room noise, which large diaphragm condensers are known to capture.
The overall sentiment is that it exceeds expectations, especially considering its price. Reviewers appreciate its warm sounds that you normally would only find on more expensive units, with smooth and extended frequency response that works well for singing and speech applications as well as for miking acoustic instruments.
Some reviewers warned that this mic has a plastic exterior, so it does not feel as sturdy as its more expensive counterparts. But they attest that it can get the job done even on the road, with proper handling. A few users also complained about latency issues.
The U37 does what it is intended to do quite well, and it does so without much in the way of compatibility complications. We were recommending it until the 14th of February 2018 but we took it off our recommended list because there are now more highly rated options available which you will find in these guides:
