Shure 55SH Series II Retromikrofon

Shure 55SH Series II — The Iconic Unidyne Vocal Microphone

The Shure 55SH Series II carries the unmistakable silhouette of the original Unidyne microphone, updated with modern acoustic components for today's performers. Its chrome die-cast construction and tailored vocal response make it a natural fit for podcasting, broadcasting, and live stage work. The cardioid pickup rejects sound from the rear, allowing the mic to sit close to stage monitors without feedback. At 0.624 kg, it feels solid on a stand without becoming a burden during long sessions.

What makes this model stand out

Few microphones look like this one — the chrome die-cast housing and art-deco head shape are unmistakable on camera. A shock-mounted moving-coil cartridge keeps stand noise out of the recording, while the self-tensioning swivel mount tilts 45° forward and 80° backward. An integrated On/Off switch adds hands-on control that many modern stage mics have dropped.

Specifications that shape the sound

Tuned specifically for spoken word and singing, this model carries a presence peak that helps vocals cut through a mix. The dynamic capsule needs no phantom power, so it plugs straight into any XLR input on a mixer or audio interface.

• Frequency Range: 50 Hz – 15 kHz — tailored for speech and vocals
• Polar Pattern: Cardioid — rejects rear sound for high gain before feedback

• Weight: 0.624 kg — solid feel without being stage-heavy
• Housing: Chrome-plated die-cast metal — built to survive daily use

Who should reach for the 55SH Series II

The 55SH Series II is the right choice for vocalists and broadcasters who want a microphone that looks as distinctive as it sounds. Tribute performers channeling the Elvis era appreciate the unmistakable silhouette, while small-stage PA users benefit from the cardioid pattern's feedback resistance. Content creators — streamers, YouTubers, radio hosts — get a mic that doubles as a set piece on camera. Theater techs and house-of-worship sound operators will find the rugged die-cast body ready for repeated setup and teardown.

The Unidyne legacy

The Unidyne cartridge at the heart of this microphone was developed by Shure engineers Ben Bauer and Ernie Seeler, whose single-element unidirectional design dates to the late 1930s. By pairing the original visual identity with modern acoustic components, this model keeps that heritage alive in working form.
