Overview
Plantronics was an American manufacturer of audio communications equipment for business and consumer users. The company became especially associated with lightweight headsets for aviation, air-traffic control, telephone operators, call centers, unified communications, mobile phones, computers, gaming, and music. Its later product portfolio included wired and wireless office headsets, Bluetooth mobile headsets, conference phones, computer peripherals, speakers, and collaboration equipment. The business originated in the early 1960s, when airline pilots and communications engineers were seeking a lighter alternative to bulky cockpit headsets. United Airlines pilot Courtney Graham worked with fellow pilot Keith Larkin to develop a compact design using small hearing-aid-style transducers mounted on a headband. After the design received airline approval, the founders incorporated Pacific Plantronics on May 18, 1961. The company introduced the MS-50 lightweight communications headset in 1962. The product gained adoption beyond aviation, including among air-traffic controllers, telephone companies, and call-center operators. Plantronics also established an important connection with the United States space program. Its SPENCOMM division worked with NASA personnel and astronauts to create compact, reliable communications equipment for spacecraft and spacesuits. Plantronics headsets were used during the Mercury and Apollo programs, and communications from the Apollo 11 lunar mission were transmitted through equipment associated with the company. This association became one of the defining elements of Plantronics' corporate history and brand identity. During the following decades, Plantronics expanded through product development and acquisitions. Its StarSet headset, patented in the early 1970s, used a lightweight ear-supported form factor and acoustic tubes. In the 1980s, the company developed cordless products using infrared links, including equipment for conference-room communications. It later entered consumer and personal-computing audio, introducing products such as the HS1 and DSP-500 multimedia headsets in 1999. The company also developed products for Xbox Live and created a headset associated with Halo 2. Plantronics broadened its business through acquisitions. It acquired Walker Equipment in 1986, adding amplified telephone products that eventually became associated with the Clarity brand. It acquired Octiv in 2005 and used its technology in audio-processing applications. The same year, it acquired Altec Lansing, a computer-speaker company, although Altec Lansing was later sold to Prophet Equity. These activities reflected Plantronics' effort to participate in several adjacent audio categories rather than relying only on office headsets. Enterprise communications became increasingly important in the 2000s and 2010s. The 2003 CS50 helped establish Plantronics in wireless office headsets, followed by the CS70N, CS500, and Savi families. The company also developed unified-communications headsets, conference products, speakers, and collaboration tools for businesses. Consumer and gaming products included the BackBeat, Voyager, GameCom, .Audio, and RIG families. Plantronics announced its acquisition of Polycom in 2018 for approximately $2 billion. After completing the transaction, the company announced in 2019 that it would change its corporate name to Poly while continuing to trade initially as Plantronics, Inc. The Plantronics name continued to appear on products and in market references, but the corporate identity increasingly centered on Poly and enterprise collaboration. In 2019, the company exited gaming and much of the consumer market to concentrate on enterprise collaboration. HP announced an agreement to acquire Poly in 2022 for $1.7 billion in cash, with the total transaction value including debt reported at approximately $3.3 billion. The acquisition closed in August 2022, and Plantronics ceased to operate as an in…
History
Plantronics began as Pacific Plantronics in 1961, founded by United Airlines pilot Courtney Graham and pilot and engineer Keith Larkin. Their work responded to the practical problems created by the large, heavy headsets used in early jet aviation. The founders designed a compact headset using miniature transducers and a headband, and United Airlines approved the design for use in airline operations. Pacific Plantronics introduced the MS-50 to the commercial market in 1962. The company quickly gained recognition in professional communications. During the middle of the 1960s, the Federal Aviation Agency selected Plantronics as a supplier of headsets for air-traffic controllers, and the company also supplied equipment to Bell System operators. The MS-50's lightweight construction and speech-focused design made it useful in environments where workers needed to communicate for long periods while keeping their hands free. Plantronics' early history was closely connected to NASA. Astronaut Wally Schirra approached Courtney Graham about developing a compact headset for spaceflight. Plantronics created its Space Environmental Communications division, known as SPENCOMM, and worked with NASA engineers and astronauts to refine a dependable microphone and headset system. A working design was developed rapidly and used by Schirra during the Mercury-Atlas 8 mission. Related headset systems were used through the Mercury and Apollo programs, including the communications equipment associated with Neil Armstrong's first words from the lunar surface. Product innovation continued with the StarSet, patented by engineer Ken Hutchings and introduced around 1970. The design placed the receiver and microphone in a compact housing supported near the ear, using acoustic tubes for sound transmission. In the 1980s, Plantronics expanded into cordless communications using infrared technology. These systems connected portable transmitters with base units attached to telephone networks and included an early echo-free conference-room speakerphone. The company expanded into adjacent businesses through acquisitions. Walker Equipment, acquired in 1986, produced amplified handsets and telephones for people with hearing loss; its business later developed into the Clarity product line. Plantronics acquired Octiv in 2005 and renamed its technology operation Volume Logic. It also acquired Altec Lansing in 2005, adding a computer-speaker brand, but sold Altec Lansing to Prophet Equity in 2009. Plantronics entered personal-computer audio in 1999 with the HS1 and DSP-500 headsets. It later developed computer, online-gaming, and console-gaming products under labels including GameCom, .Audio, and RIG. In 2002, it worked with Microsoft on the Xbox Communicator headset for Xbox Live voice communication, and it produced a Halo 2-related headset in 2004. In mobile audio, Plantronics developed Bluetooth products such as the Pulsar 590. In office communications, the 2003 CS50 helped establish a major wireless-headset product family, later followed by the CS70N, CS500, and Savi ranges. Plantronics' strategic focus increasingly moved toward unified communications and enterprise collaboration. The company announced its acquisition of Polycom in March 2018. After the transaction, it announced in March 2019 that the corporate name would become Poly, although its public-company identity initially remained Plantronics, Inc. The company subsequently emphasized enterprise collaboration and exited gaming and consumer markets in 2019. HP announced the acquisition of Poly in March 2022, offering $1.7 billion in cash and assuming debt in a transaction with an aggregate value of about $3.3 billion. The deal closed in August 2022, ending Plantronics' existence as an independent company and placing its products and technologies within HP's hybrid-work portfolio.
