Build of the Fifine K669
The Fifine has a sturdy feel about it in terms of design. It contains a durable 1.8-metre wire, a good-weighted metal body, and nice-quality metal mesh.
To keep it upright while in use, it also has a convenient tiny tripod and pivot mount.
Although the tripod’s quality isn’t quite as good as the microphone, it will work just fine if you’re recording at your workstation.
Sadly, there is no headphone jack; there is only a volume control right on the mic. However we can’t get over the fact that it’s quite tiny (1409050 mm), it is easy to move and won’t take up much space wherever you choose to place it.

The simplicity of usage is probably one of the best features of this microphone. With no drivers or software needed to get started, it is compatible with Mac OS, Windows, and Linux.
All you need to do is plug it in to start using it! The correct drivers should be installed on your machine instantly.
The sound quality of the Fifine K699B
The Fifine K669B is a condenser mic with a cardioid pattern, similar to many widely used microphones. This indicates that the majority of the audio is captured from the front, making it ideal for radio broadcasting and podcasting. You’ll get the best results by holding it squarely in front of you. Any background noise is also restricted by the cardioid pattern.
Place the microphone approximately 10 cm away from your mouth for a clear, sharp sound.
