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.
