Shure Nexadyne Review | Podcastbricks

For nearly a century, Shure has been synonymous with excellence in audio engineering, particularly in the realm of dynamic vocal microphones. From the groundbreaking Unidyne Model 55 in 1939 to the ubiquitous SM58 introduced in 1966, Shure has consistently set the benchmark for live sound. Now, in 2025, the company has unveiled the Nexadyne series—a bold step forward in microphone technology that promises to redefine what performers and sound engineers can expect from a dynamic mic. Featuring the patented Revonic Dual Transducer Technology, the Nexadyne lineup, available in cardioid (8/C) and supercardioid (8/S) variants, aims to deliver unparalleled clarity, noise rejection, and consistency. But does it live up to the hype? In this eview, we’ll dive into the design, performance, and real-world applications of the Shure Nexadyne, exploring whether it’s poised to become the new gold standard for live vocal performance.

A Legacy of Innovation

To appreciate the Nexadyne, it’s worth understanding the legacy it builds upon. Shure’s history is peppered with milestones that have shaped the audio industry. The Unidyne Model 55, designed by Ben Bauer, introduced the world to the first single-element unidirectional dynamic microphone—a breakthrough that laid the groundwork for modern directional mics. The SM58, released in 1966, became the industry standard for live vocals, prized for its durability, versatility, and distinctive sound profile. In 2016, Shure pushed boundaries again with the KSM8 Dualdyne, the first dynamic microphone to employ dual diaphragms, offering a refined, condenser-like sound with exceptional off-axis rejection.

The Nexadyne series is the latest chapter in this storied narrative. Launched in 2024, it arrives at a time when live sound demands are higher than ever—venues vary wildly in acoustics, performers push their gear to the limit, and engineers seek tools that minimize corrective processing. Shure’s answer is the Nexadyne 8/C (cardioid) and 8/S (supercardioid), available as wired XLR microphones or wireless capsules compatible with Shure’s Axient Digital, ULX-D, QLX-D, and SLX-D systems. Priced at $299 each, these mics are positioned as premium yet accessible options for professionals. But what sets them apart? The answer lies in their Revonic technology and meticulous design.

Revonic Technology: The Heart of Nexadyne

At the core of the Nexadyne series is Shure’s patented Revonic Dual Transducer Technology—a dual-engine design that uses two precisely matched transducers (diaphragms, voice coils, and magnets) working in tandem. Unlike traditional dynamic mics with a single diaphragm, the Revonic system employs acoustic signal processing to enhance on-axis sound while attenuating off-axis noise. The top transducer captures sound from the front, while the second, positioned to react to sound entering side ports, cancels out unwanted vibrations and handling noise through phase relationships. This isn’t just a gimmick—it’s a sophisticated engineering feat that required Shure to achieve tight manufacturing tolerances to ensure consistency across units.

The result? A microphone that promises a flatter frequency response, reduced proximity effect, and superior polar pattern linearity compared to its single-transducer predecessors. Shure claims this translates to less need for EQ, better feedback resistance, and a more natural off-axis sound—attributes that could save engineers time and elevate performances. But theory is one thing; real-world performance is another. Let’s examine how the Nexadyne delivers.

Design and Build Quality

Shure microphones are renowned for their ruggedness, and the Nexadyne series upholds this tradition. The 8/C and 8/S feature die-cast aluminum bodies with a sleek, satin-black finish (wireless capsules also come in nickel). Weighing 9.1 ounces (8/C) and 10.3 ounces (8/S), they’re slightly lighter than the SM58 (10.5 ounces), though the difference is subtle in hand. The grille, made of dent-resistant hardened steel, features a modern design—ribbed on the supercardioid 8/S to distinguish it from the smoother 8/C. Inside, the Revonic capsule is housed in a robust rubber enclosure that absorbs shock, eliminating the need for a traditional pneumatic shock mount.

The packaging reflects Shure’s commitment to sustainability, using minimal printed cardboard, and each mic comes with a zippered case, mic clip, and brass stand adapter. The build feels bulletproof—drop it, toss it in a gig bag, or hand it to an overzealous vocalist, and it’s likely to emerge unscathed. Visually, the Nexadyne departs from the iconic “ice cream cone” shape of the SM58, opting for a more contemporary, cylindrical profile that looks sharp on stage.

Sound Profile and Performance

The true test of any microphone is its sound, and the Nexadyne doesn’t disappoint. Available in cardioid (8/C) and supercardioid (8/S) polar patterns, it caters to different stage needs. The 8/C offers a wider pickup area, ideal for vocalists with less precise mic technique, while the 8/S provides tighter rejection, perfect for noisy stages or monitor-heavy setups. Both models are transformerless, with output impedances of 300Ω (8/C) and 450Ω (8/S), and deliver higher-than-average output levels (-54 dBV/Pa for 8/C, -51 dBV/Pa for 8/S) compared to the SM58 (-56 dBV/Pa). This extra gain is a boon for long cable runs or quieter vocalists.

Frequency Response

Unlike the SM58, which has a pronounced presence peak around 4-6 kHz to cut through a mix, the Nexadyne opts for a bolder, brighter sound with emphasis in the high-mids and highs (around 3.5-4 kHz). The low-mids and lows are more linear, reducing the boomy proximity effect common in traditional dynamics. This makes the Nexadyne sound more “open” and articulate—closer to a condenser mic than the SM58, though it retains the warmth and robustness of a dynamic. In a mix, vocals sit forward naturally, requiring minimal EQ to achieve clarity.

Noise Rejection

The Revonic technology shines in noise rejection. Handling noise is remarkably low—quieter and “deader” than an SM58—thanks to the out-of-phase wiring of the dual transducers. Stage bleed and mechanical vibrations are similarly minimized, allowing the mic to isolate vocals even in chaotic environments. The polar patterns are impressively consistent across frequencies, with the 8/C maintaining a tight cardioid shape and the 8/S offering precise supercardioid rejection. Feedback resistance is excellent; both mics can handle significant monitor levels before ringing, typically around 4 kHz, though this varies by venue.

Real-World Testing

In practical use—say, a weekend festival with multiple acts—the Nexadyne proves its worth. The 8/S excels as a lead vocal mic, cutting through dense mixes with a natural, non-harsh top end that flatters a range of voices. The 8/C, used for backing vocals, offers a forgiving sweet spot and reduced boominess up close, making it versatile for singers who “eat the mic” or maintain distance. Compared to the SM58, the Nexadyne requires less EQ to tame lows or boost presence, and its clarity reduces monitor requests from vocalists—a win for engineers.

Comparisons to Competitors

The Nexadyne enters a crowded field of premium dynamic mics. How does it stack up?

Shure SM58: The SM58 remains the workhorse—cheaper ($99 vs. $299), slightly darker, and more forgiving of rough handling. The Nexadyne offers superior clarity and rejection but lacks the SM58’s iconic familiarity.
Shure Beta 58A: With a similar output level (-51.5 dBV/Pa) and tighter supercardioid pattern, the Beta 58A is a closer rival. The Nexadyne 8/S edges it out in noise rejection and mid-range detail, though the Beta is less expensive ($169).
Telefunken M80/M81: Priced around $249-$299, these mics compete directly with the Nexadyne. The M80’s crisp top end can be too much for sibilant voices, while the smoother M81 requires minimal EQ. The Nexadyne strikes a balance—brighter than the M81, more controlled than the M80.
Sennheiser e945: At $200, this supercardioid dynamic offers a refined sound and great rejection. The Nexadyne 8/S matches its clarity but surpasses it in handling noise reduction and output.

The Nexadyne’s Revonic technology gives it an edge in technical innovation, but its higher price and departure from the SM58’s tonal signature may deter traditionalists.
