Pros
Work/life balance is exceptional. Virtually no schedule pressures. Very low employee attrition. A great place to settle in and retire from (assuming the brand remains strong). Mr Shure who founded the company in 1925 would be happy that some aspects of his small company standards and culture still exist today even as the company continues to grow.
Cons
Engineering expertise and project management is surprisingly very poor. Many have worked here for decades and promoted upwards over time as managers who draw on their smaller company, lower-tech experience. These managers promote their people who've learned from and been with them for decades. As a result much of the engineering organization is out of touch with today's mainstream engineering/technology norms. They do work hard, just not nearly as smart as other organizations. Most companies in today's technical world wouldn't survive long with such inefficient engineering but Shure has a strong brand/name bringing in solid profits to subsidize. Also, much of the more innovative design work is out-sourced so less is expected from Shure engineering. To be fair, they do a pretty good job integrating technology, as opposed to designing it. Mr Shure who was obviously an exceptional innovative engineering entrepreneur of his time would be disappointed with today's layers of engineering management who haven't kept up with technology nor engineering practices.
