Main Intelligence Directorate (Russia)
Main Intelligence Directorate (Russian: Гла́вное разве́дывательное управле́ние, tr. Glavnoye razvedyvatel'noye upravleniye; IPA: [ˈglavnəjə rɐzˈvʲɛdɨvətʲɪlʲnəjə ʊprɐˈvlʲenʲɪjə]), abbreviated GRU (Russian: ГРУ; IPA: [geeˈru]), is the foreign military intelligence main directorate of the General Staff of the Armed Forces of the Russian Federation (formerly the Soviet Army General Staff of the Soviet Union). The official full name is Main Intelligence Directorate of the General Staff of the Armed Forces of the Russian Federation (Russian: Гла́вное разве́дывательное управле́ние Генера́льного шта́ба Вооружённых Сил Росси́йской Федера́ции). It is also known as GRU GSh (Russian: ГРУ ГШ; abbreviation of ГРУ Генера́льного шта́ба, tr. GRU Generalnovo Shtaba (English: GRU of the General Staff)).
The GRU is Russia's largest foreign intelligence agency. In 1997 it deployed six times as many agents in foreign countries as the SVR, the successor of the KGB's foreign operations directorate. It also commanded 25,000 Spetsnaz troops in 1997.
Pulsar
A pulsar (short for pulsating radio star) is a highly magnetized, rotating neutron star that emits a beam of electromagnetic radiation. This radiation can be observed only when the beam of emission is pointing toward Earth (much the way a lighthouse can be seen only when the light is pointed in the direction of an observer), and is responsible for the pulsed appearance of emission. Neutron stars are very dense, and have short, regular rotational periods. This produces a very precise interval between pulses that range roughly from milliseconds to seconds for an individual pulsar. Pulsars are believed to be one of the candidates of high and ultra-high energy astroparticles (see also Centrifugal mechanism of acceleration).
The precise periods of pulsars make them useful tools. Observations of a pulsar in a binary neutron star system were used to indirectly confirm the existence of gravitational radiation. The first extrasolar planets were discovered around a pulsar, PSR B1257+12. Certain types of pulsars rival atomic clocks in their accuracy in keeping time.

Pulsar 590
Pulsar 590A and Pulsar 590E are bluetooth headsets. They are designed for use with bluetooth and A2DP (for stereo listening) enabled cellphones; including many Nokia, Sony, LG Group, Motorola, and Palm models; most other bluetooth enabled devices; or with the Plantronics universal adapter. Unlike most bluetooth headsets, the Pulsar 590A/E has stereo capabilities, meaning it can do two separate audio channels.

Critical reception
CNet gave the 590A 3.5/5, praising the battery life, sound quality, and ease of use, and reporting sound quality was quite good though people could still tell you were talking on a cellphone. Mobile Tech Review praised its sound quality, bluetooth performance, and looks, and gave it 4.5/5. Stuff gave it 5/5, finding the styling a bit too "office"-like, but otherwise positive.
