if your Shure mic is broken, this is probably why
My Sure SM7DB, as others had also experienced (and even made videos on), was not working on arrival (yes, it was official).
The mic would pickup a sound if tapped but not anything external.
I opened it up and the wires were so insanely short, paired with the awful soldering and the lack of literally any sort of wiggle room meant the wires would just break off from its solder. This meaning no connection. (It would’ve cost around 0.05p just to extend those cables just a little bit longer).
An official repair would be £350 which is the most ridiculous thing I’ve ever heard - especially for a manufacturing error. It is an expensive microphone so there really isn’t any excuse for the manufacturing to be as poor as it was. Highkey think it may have been on purpose as it’s more lucrative to repair a dishonest mistake.
My dad actually managed to repair it himself, changed the wire length (replacement) and had to unsolder and re solder every single wire for £2 for the amount of solder spool we needed. The total repair cost was £2 and time wasted.
It’s a shame for the amazing quality the microphone input actually is.
