Shure first began manufacturing their own products in 1932 with the introduction of the 33N two-button carbon microphone. The Model 40D, Shure's first condenser microphone, was introduced the next year, and the first of a line of crystal microphone, the Model 70, was introduced in 1935. With the introduction of the 55 Unidyne microphone in 1939, the company's offerings included carbon, condenser, crystal, and dynamic microphones. Wired and wireless microphones together represent the largest category of Shure's overall business. Shure currently produces numerous series of microphones for various applications, including the SM, Beta, KSM, and PG series, as well as specialty consumer microphones, Microflex, and Easyflex (conferencing systems for commercially installed applications).
One of Shure's most visually iconic microphone series is the Unidyne series, seen in use by heads of state and popular recording artists and performers from the 1940s through the end of the twentieth century, including President John F. Kennedy, Ella Fitzgerald, and Frank Sinatra. The Model 55 Unidyne is pictured with Harry S. Truman in the photograph where he is holding the Chicago Tribune newspaper with the erroneous front-page headline "Dewey Defeats Truman". It is also pictured in front of Fidel Castro on the cover of the January 19, 1959, issue of Life magazine and in front of Martin Luther King Jr. as he delivered his "I Have a Dream" speech during the August 1963 March on Washington for Jobs and Freedom. The original Shure 55 Unidyne microphone was designed by engineer Ben Bauer and first produced in 1939. Shure designed the 55 Unidyne as a rugged public address microphone with good audio performance. It was notable for its single-element, unidirectional design, which was smaller, less susceptible to feedback, and less sensitive to ambient noise than other microphones of the time. Several variants of the original Unidyne have been produced, most notably the 55S or "Baby Unidyne". The 55S is sometimes referred to as the "Elvis mic" due to its frequent use by Elvis Presley, and is the microphone depicted with Elvis on the commemorative first-class Elvis stamp issued by the U.S. Postal Service in 1993. In 2008, the Unidyne Model 55 microphone was inducted into the TECnology Hall of Fame, and the following year, Shure released the 55SH Series II. A supercardioid version, the Super 55 Deluxe Vocal Microphone, was introduced in 2009, featuring high gain before feedback and excellent off-axis rejection and further extending Unidyne's 70-plus year legacy. The 55 Series microphones were given the "IEEE Milestone" award in 2014.
With the U.S. Army's approval of the Shure T-17 microphone for use during World War II, Shure began producing what would be several specialized microphones for U.S. military use during that war. Shure's adoption of the Military Standard Specification, and product redesigns intended to conserve raw materials essential to the war effort, positioned the company to fulfill the military's needs for specialized microphones. The T-17 Battle Announce Microphone was the most widely used microphone in the U.S. Army and Air Force during World War II, and featured a plastic case that conserved aluminum and lighter and more reliable in a wide range of temperatures and climates. A waterproof version was used on nearly all U.S. Navy ships. Shure also designed the T-30 Throat Microphone for flight crews. A cloth strap held the T-30 against the throat, capturing the user's voice box vibrations directly and avoiding the background noise of the airplane. Shure also manufactured specialized headsets and the MC-1 oxygen mask microphone. In yet another example of the widespread use of Shure microphones by the U.S. military, U.S. lookout Private Lockhard used a Shure 700A microphone to announce his sighting of Japanese planes approaching Pearl Harbor on the morning of December 7, 1941.
The Shure SM series of microphones began with the introduction of the SM57 in 1965 and the SM58 in 1966. The SM (Studio Microphone) series microphones were originally developed with a non-reflective finish and no on-off switch for the TV studio market. The SM57 is well known for its durability and the versatile sound characteristics, much attributable to the Ernie Seeler-designed Unidyne III capsule. Produced since 1965 and still in production today, it has been widely used in many applications, including micing vocals, drums, and guitar amplifiers both in live sound and recording applications, including being used by every United States President from Lyndon Baines Johnson on. The SM57 was inducted into the TECnology Hall Of Fame in 2004. Together, the Shure SM57 and SM58 have been the two bestselling microphones in the world since the late 1960s. Their feature set is nearly identical, with the main difference between the two being their different grilles. Shure later expanded the SM series, which now include such models as the now hard to find SM53 & SM54 (which were low proximity effect microphones), SM45, SM48, SM56, SM57, SM58, SM85, SM86, SM87A, SM94, and the SM81 which is a longtime recording studio standard.

Shure introduced Beta Series microphones in 1989. These feature a supercardioid designs based on SM series microphones, but with neodymium magnet structures for higher output. The series also included two new microphones specifically for drums, the Beta 56 drum microphone and the Beta 52 kick drum microphone, later updated to the Beta 52A. The Beta 58A microphone was awarded a TEC award in 1996, and several other Beta series microphones have been nominated for TEC awards over the years.
Shure's first headset microphone for stage use was created in 1991. One of the earliest uses of a Shure headset mic onstage was for the television special Medusa: Dare to be Truthful. Among the headset microphones Shure has manufactured over the years are the WH20, WH30, WCM16 (introduced in 1993), Beta53 and Beta54. The newest of Shure's headset microphones, the MX153, part of the Microflex series, was introduced in 2012.
In 1999, Shure introduced the first mic in their KSM Series of premium recording microphones, the KSM32. KSM series microphones feature Class A discrete transformer-less preamplifiers. Ten years later in 2009, Shure acquired Crowley and Tripp Ribbon Microphones from Soundwave Research Laboratories of Ashland, Massachusetts, along with the company's proprietary "Roswellite" ribbon material, and added both ribbon microphones, now rebranded the KSM353 and KSM313, to the KSM series.
Shure brought out the SM5 microphone in 1966, intended for broadcasting applications. In 1973, the SM5 was updated and reduced in size to become the SM7, which was widely adopted by television and radio announcers, but occasionally used in recording studios to pick up vocals, horns, guitars or bass drums. Both the SM5 and SM7 were built on the SM57-type Unidyne III element as the core transducer, tailored for lower frequency response. Engineer-producer Bruce Swedien used the SM7 to record Michael Jackson's vocals for Thriller. In 1999 the SM7A model appeared with beefed-up shielding against electromagnetic interference (for instance from television CRTs), and in 2001 the SM7B model added a larger windscreen. In 2001–2003, the SM7 was used to record heavy metal vocalist James Hetfield for the Metallica album St. Anger, as seen in the documentary Metallica: Some Kind of Monster. The SM7B was radically redesigned in 2020, reduced in size and provided with active digital audio circuitry to become the MV7, with both XLR and USB connections. The MV7 swiftly picked up a large share of the podcasting market, and was named the best podcast microphone by Rolling Stone magazine in 2021.
Phonograph cartridges
Shure began supplying replacement crystal pickups to various manufacturers in 1933 and by the mid-1940s Shure was the largest supplier of phonograph cartridges in America, supplying record manufacturers like Philco, RCA, Emerson, Magnavox, Admiral, and Motorola. At the peak of Shure's production the company was producing more than 28,000 cartridges per day, with 25,000 produced at Shure's Phoenix plant. While Shure continues to manufacture phono cartridges, the Phoenix facility was closed in the late 1980s due to declining demand.
Shure engineers introduced several key phono cartridge design concepts. Chief engineer Ralph Glover discussed the pickup design relationship to record wear in a 1937 article in Electronics magazine entitled "A Record-Saving Pickup". Glover developed the "needle-tilt" principle with the assistance of fellow Shure engineer Ben Bauer, and considerations of needle angle, record wear, and fidelity were an integral part of Shure's cartridge designs. In 1966, chief engineer Jim Kogen published a research paper entitled "TRACKability" in Audio magazine, defining the concept as the ability of a cartridge to maintain contact with a record groove through any modulation.
Shure is credited with several industry firsts. In 1948, the company introduced the 900MG, the first phonograph cartridge capable of playing both long-playing and 78 rpm records, and in 1954, Shure's M12 Dynetic Phono Reproducer tonearm and cartridge set established an industry standard with a tracking force of only one gram. The M1 Studio Dynetic Cartridge introduced the principle of a moving magnet within a stationary coil, an engineering concept that dominated cartridge design for nearly 25 years due to its higher output, lower noise, and greater headroom. The Shure M3D, introduced in 1958, was the first ever stereo moving magnet cartridge, with 20 dB of stereo separation at 20 kHz.
Shure has also designed and manufactured cartridges specifically for disc jockeys. Their M35X and Whitelabel cartridges are designed for nightclubs. The M44-7, however, is designed for scratching, which involves playing a vinyl record forward and backward rhythmically. The M44-7 cartridge is renowned for its tracking and skip resistance, which has made it a popular choice of turntablists such as The Invisibl Skratch Piklz.
Shure's flagship V15 phonograph cartridge series, with the model name referring to their 15-degree tracking angle, was established for decades as the premier cartridge for low tracking force and high tracking ability. The V-15 series also included several industry firsts: the original V-15 model (introduced in 1964) was the first to feature "trackability", and utilized a symmetrical, bi-radial elliptical stylus. The V-15 Type II (introduced in 1966) was the first computer-designed phono cartridge and the first to feature a flip-action built-in stylus guard. The V-15 Type IV (introduced in 1978) was the first to feature the dynamic stabilizer, which discharged static electricity from the groove and stabilized the cartridge for playback of warped records. The V-15 Type V marked the introduction of a proprietary "ultra-thin wall beryllium" stylus shank with a stiffness-to-mass ratio several times that of other cartridges on the market. In 1998, Sony Music Entertainment selected the Shure V15VxMR to transcribe 80 years of Columbia Records and Sony Music masters and recordings. In 2008, the British Gramophone magazine awarded the V-15 an "Audio Choice" designation for outstanding performance and value. Due to the scarcity of the raw materials required to manufacture V-15 cartridges, Shure discontinued the series in 2004, and in June 2009, the last remaining V-15 stock was purchased by the Library of Congress. On May 1, 2018, Shure publicly announced that they would be ceasing production of all phono products, effective Summer 2018.
Sound reinforcement systems
Shure introduced the Vocal Master sound reinforcement system, touted as "the first portable total sound system", at the 1968 winter NAMM Show. The Vocal Master system consisted of a combination of control consoles, speakers, amplifiers, mixers, and microphones. Multiple components and systems could be combined to expand the Vocal Master system to larger sound reinforcement applications. The Vocal Master was at one time the official on-tour sound system for performing acts such as the 5th Dimension and the Carpenters among others. Vocal Master was also utilized for installed sound applications in educational institutions and churches, as well as at the Rockefeller Center's Rainbow Room where it was used for performances by such artists as Benny Goodman and Duke Ellington, and at the London Palladium.
Mixers and DSP
In 1966, Shure introduced the M68, a portable mixer capable of being battery powered along with available accessories like a carry case and battery power supply specifically designed to address the needs of broadcast journalists and field recording personnel. The following year, the Shure M67 mixer added an illuminated VU meter and a line level output transformer for connecting the mixer to a telephone line. In August 1969, Eddie Kramer recorded the 4-day Woodstock Festival using three Shure M67 mixers. Shure's portable mixer line later included other models such as the M267 and 268.
Shure introduced the FP31 mixer in 1983. The FP31 was smaller and lighter than similar products of the time—small enough to hold in the palm of the hand and weighing just 2.2 pounds. This positioned it to complement the one-piece Sony Betacam video camera, which had been widely adopted by remote video broadcast crews. The FP31 could operate up to eight hours on two standard 9-volt batteries, and included two separate microphone/line outputs for two-camera video shoots. Its master section featured an adjustable threshold limiter to prevent overload distortion, and there was a separate microphone/line switch with low-cut filter on each channel. By 1984, just a year after its introduction, the FP31 was being used by ABC, CBS, NBC, Turner Broadcasting System, and was later succeeded by the Shure FP33.
In addition, Shure introduced other portable products useful to broadcast remote and field recording, such as FP11 Microphone-To-Line Level amplifier, the FP12 Headphone Bridging amplifier, and the FP22 Headphone amplifier.
In 1991, Shure introduced the FP410 automatic mixer, featuring Shure's patented IntelliMix circuitry, which automatically activates special double-element microphones based on the direction of a talker's signal. That same year, the FP410 was recognized with the Technical Achievement Award from the International Television Association for "significantly advancing the state of the art in the field of non-network television". Shure later introduced the SCM810, an 8-in, 1-out automatic microphone mixer that also featured Shure IntelliMix circuitry.
Shure also introduced digital signal processing products for this market, beginning with the DFR11EQ digital feedback reducer (introduced in 1996) and the DFR22 2-in, 2-out feedback reduction audio processor.
Conferencing systems
Shure introduced the Automatic Microphone System (AMS) in 1983, one of the first automatic, high-quality mixer system using directional gating for installations utilizing multiple microphones. In 1987, Shure SCM810 Automatic Mixer installations begin at the United States Capitol, and by 1997, the US Capitol was one of the largest Shure automatic mixer installations in the world. In 2008, Shure introduced the Microflex microphone line specifically designed for conference room applications.
In 2013 Shure launched the Microflex Wireless (MXW) System, its first dedicated wireless microphone solution for boardrooms. In 2016 the company debuted Microflex Advance (MXA) Array Microphones for conference room audio, including the MXA310 Table Array and the MXA910 Ceiling Array, which introduced "steerable coverage" technology.
In 2017 Shure released the IntelliMix P300 Audio Conferencing Processor, with centralized acoustic echo cancellation, noise reduction, and automatic mixing. SystemOn Audio Asset Management software was released in 2018, for IT/AV managers to remotely monitor networked audio gear across large corporate buildings.
In 2019 Shure announced Microflex Complete Wireless (MXCW), consisting of wireless conferencing units which include a microphone, loudspeaker, interpretation audio, controls, and touchscreen, intended for conferences, meetings, and events inside government, corporate, hotel, and educational facilities.
In 2020 Shure introduced IntelliMix Room, offering DSP algorithms as native Windows software for video conferencing.
In 2023 Shure launched the MXA902, an integrated conferencing ceiling array and a wide-dispersion loudspeaker in a single form factor. In 2024 it released Microflex Wireless neXt 2 (MXW neXt 2) for hybrid meetings and presentations, followed in 2025 by 4- and 8-channel options.
In 2025, Shure announced the expansion of its Microflex Ecoystem portfolio with the MXP range of passive loudspeakers, including pendant, wall and ceiling mounted models, as well as the MXN-AMP, a multichannel, PoE+ powered networked amplifier.
Also in 2025, Shure launched pre-packaged IntelliMix Room Kits featuring zero-touch provisioning, cloud management, and built-in DSP for Microsoft Teams Rooms, with support for Zoom Rooms following in June 2026. The kits include Intellimix Room DSP software, touch panel, network switch and accessories, in addition to a number of MXA902 Ceiling Array Microphone + Loudspeakers and Huddly cameras depending on room size. Launched in tandem, the Intellimix Foundation System provides the compute and touch panel from the room kits as a standalone base kit, also compatible with both Microsoft Teams Rooms and Zoom Rooms.
Wireless microphone systems
Shure manufactures several lines of wireless microphone systems, many of them utilizing microphone capsules from their wired microphones models such as the SM58, SM87, Beta 58, and Beta87A. The systems range in scope from entry-level to high-end systems used for touring and large-scale event applications.
In the early 1950s, Shure introduced the Vagabond 88 wireless microphone system. Operating within a copper wire circle either suspended from the ceiling or laid on the floor, the system could transmit within an area of approximately 700 square feet. The system consisted of a low-frequency FM radio transmitter and microphone, utilized five subminiature vacuum tubes, and was powered by two hearing aid batteries. The Vagabond system was expensive and somewhat fragile, but was adopted for use by several Las Vegas venues of the time.
Not until 1990 did Shure re-enter the wireless microphone market with the introduction of the L Series. Even before Shure re-entered the wireless microphone market though, concert engineers commonly specified Shure microphone capsules for the wireless microphone systems they were using. Once Shure introduced its own UHF wireless microphone system, which featured wireless versions of several popular Shure microphones, they no longer made capsules available for other manufacturers' systems. This practice encouraged sales of Shure wireless systems and gained Shure market share in the category. Shure's UHF system featured software control and the ability to operate as many as 78 systems simultaneously.
The ULX series (introduced in 2002) featured their patented "audio reference companding", a level-dependent companding protocol that does not compand low-level audio where the wireless artifacts would be more audible, as well as the ability to scan for clear wireless channels, a less expensive package, and the ability to operate 40 systems simultaneously. The ULX system was awarded a TEC Award in 2002.
