Sony WF-1000XM4 Vs WF-1000XM3 - Unboxing & Mic Test | Big Improvement?

Are the mics better on the Sony WF-1000XM4 vs WF-1000XM3 ? Well in this video I put them to the test. This is also the first time that I've been able to see & hear these. So this video is also a 1000XM4 unboxing video as well ;) Feel free to skip ahead to the microphone test if you want to.
