A long history of this brand have given us dozens of groundbreaking microphones, that helped musicians and singers hit top of charts, but there is a model which stands above aforementioned and of course this is 55 Unidyne. 

More than 75 years ago Shure released an iconic microphone 55 Unidyne. During decades most famous celebrity used this microphone and made it even more iconic in music world. Among them were such persons as Frank Sinatra, Billy Holyday and of course Elvis Presley. Since than this mic was used on radio stations, meetings, and even in announcement halls on railway stations. This mic was the only one with cardioid polar pattern and one dynamic element back then.  This masterpiece had internal transformer that is why its weight was above 600gram. But enough history, let’s talk about Shure 5575LE 75th anniversary limited edition, that made this iconic model almost perfect technically.

Design

The 5575le have the same design, which became more recognizable than the face of Richard Nixon. Fully metal plate with noticeable red foam and brand logo. Metal stand complement overall design. There are no knobs and buttons only this monolithic structure, which have elegant look and design is another reason to get it (besides quantity limits of edition). Also with this mic you will get flight case which looks expensive and solid so you can be sure that during flight this mic will be in safety. Moreover, set includes photo prints of Unidyne models and Certificate of Authenticity as pleasant addition to overall pack.

Sound Quality

The question is if design of this model remains the same, does the hardware change? The answer is positive. Simple logic: how could this model remain popular if it was all the same inside? And it was not, so let’s talk about innovations of hardware. Firstly, this model got modern cardioid element ‘Unidyne’ of the third generation. That is why it is impossible to say that the quality of sound is excellent – it is extraordinary warm sound which automatically make you fan of this mic. Secondly connection type is presented with XLR sockets, which makes this model more corresponsive to contemporary trends.

Shure 5575LE vs Shure Super 55

At the request of readers, we compare Shure 5575LE and Shure Super 55. First of all, microphones vary in size from each other, for example Shure 5575Le is larger as it made as original 55 model from 1939. The second difference is in polar patterns 5575LE has a cardioid element, like the SM58. The Super 55 has a supercardioid element, like the Beta 58A. It is worth noting that Shure 5575LE sounds a little bit warmer as you can hear in audio example above.

Final Verdict

To be honest, we cannot recommend this model to everyone as we did in 55SH and 55 Super Deluxe reviews because technically this model is not way better than 55 Super Deluxe and at the same time it is more expensive. This model was intended for truly lovers of Unidyne model, for those who want to have one and do not use it, just for the collection. And of course this model is must have for every recording studio as a tribute of respect to this iconic model and the Shure company as well.
