The Blue brand is known for its high-quality studio microphones. Nowadays, Blue also makes USB microphones. Blue USB microphones are ideal for recording vocals, podcasts, and streams. You don't need an external sound card to record sound, because you connect the Blue microphone directly to your PC or laptop. Thanks to the switchable direction characteristic, you determine on which side the microphone is sensitive. This way, you can set which side the microphone will record sound on.
