Do you guys have any good or bad experiences with this mic?
The Shure 444 microphone is techncially, very well designed and well supported by Shure (the manufacturer).
Thousands of these microphoens were produced and sold for public address (e.g. shopping malls, schools, bus/train terminals, dispatch offices) and radio base station/fixed usage (land mobile, amateur radio).
There were serveral VERSIONS (five) of the Shure 444 / 450 series microphones. Shure publishes User Guides for their microphone that contains ALL the information a compentent electronics, music/theatre tech, or radio technican requires for hook-up.
The appeal of the 444 design is a PERSONAL choice/preference (Form follows function).
As far as voice / audio performance, only YOU can match your unique voice characteristics (bassy, tinny, mumbles) to the microphone frequency response (shown in the User Guide chart).
