I’ve been very happy with the Sennheiser e935 mic I’ve probably been using it exclusively for at least 7 years maybe more. Today while using it I found some distortion/cracking of my vocals. Just for the heck of it I switched to my Samson Q7 and the Samson sounded much better. Although I like the Q7 the e9355 was always better. I think it’s time for a new e935 but for you experts and in trenches daily musicians can a mic go bad or just lose it after 7 years?
