Plantronics' customers appreciate its hands-off approach. The company makes lightweight communications headsets that can be worn over the head, behind the ear, or in the ear, freeing hands for other tasks. Its other products include the Clarity brand of amplified telephone handsets for hearing-impaired users, text telephones, emergency response systems, and mobile phone headsets. Serving the consumer and business markets worldwide, Plantronics sells its products through distributors, manufacturers, and communications service providers. The company gets about 56% of its sales from US customers.
