Bench Blue Yeti microphone with frequency response test

I would like to bench the performance of the Blue Yeti microphone to make sure it's good enough for speaker frequency response measurement usage, so I compare it with the high performance microphone, AKG300B(with a amplifier) that I used before. The result is as below,

blue yeti microphone/Unidirectional


The result for the two microphone looks very similar. I measure them in the same room, same environment, same distance to the same speaker.

Conclusion: Blue Yeti microphone is a not bad choice and Blue Yeti microphone is definitely a alternative for my speaker testing usage. usb cable for microphone setup is also much more convenient.

By the way, when doing the recording with the unidirectional mode, The Blue logo indicates the front of the microphone. Otherwise, the result will be different apparently.

Blue Yeti microphone contact loose issue

Few weeks ago I bought a Blue Yeti microphone, which looks a decent usb high class microphone, that has 3 capacitive microphones (tri-capsule) and different recording pattern modes. Though when I gave that a out-of-box try, I can hardly to see the sound capture working on my laptop and this is a disappointing thing. After fiddled that for a while, I found the sound capturing became work normal somehow if I cock the usb cable. The issue is not the usb connector loose issue though cause I can see the audio device "Blue Yeti" steady on my laptop. It's PCB! After disassembled the microphone, (refer to https://www.youtube.com/watch?v=rV74lXvfwaQ) I found there are two PCBs connected with 6 pins. I tried to use the multimeter to test if there's the cold soldering issue. As expecting, this is the root cause of my issue and I fixed it by soldering the joints with a wire as below pictures.
