The quality of the Shure SM7DB was decent but wasn’t the real microphone. The condition was brand new, but unfortunately it didn’t work either. When I tried to use it, plugged in my XLR cable, it only made static noises.
Whatever Shure SM7db they were trying to sell me wasn't working, only got static when testing, definitely do not recommend buying one. Cosmetically it looks fine, but the microphone did not work.
