Unfortunately, there seems to be quality control problems with these WH-1000XM3 headphones. Some reviews say they sound great, but I've personally experienced two bad headphones in a row and my co-worker also has a set that performs poorly.
First Set: You will hear everything clearly, but the other party will hear you as if you're talking through a pillow. When they speak, they will hear a echo of themselves.
After connecting with Sony, they sent me a second set with a return label for the first set.
Second Set: Greatly improved over first set, but the other party hears a bit of static on the line and the echo of themselves is still present. In addition, the right ear cup has a clicking sound even with small head movements or even moving my jaw. I can reproduce this clicking if I compress the padding with my palm.
Hoping you get a great quality set. By comparison, I have not had any problems with my Bose QC-35 and the QC-35 II is supposed to be the same.
