More Specifications

Sony Corporation is a Japanese company founded in 1946. Its headquarters is located in Tokyo. Its beginnings were humble. The first product sold under the Sony brand was a transistor radio. It was those radios that played a pivotal role in the company's expansion in the 1960s and the world quickly began to associate Sony products with a reliably stellar price-performance ratio. 

In the 1970s, Sony was severely affected by the global economic crisis. Many analysts considered the company effectively defunct and could see no future for it. However, they underestimated the famous Japanese perseverance and courage. The crisis was not a disaster for Sony; on the contrary, it served as a launching pad to even greater heights. The company recovered and soon changed the media landscape with the development of the CD and later the DVD. In the early 1990s, Sony achieved another major success with the introduction of the PlayStation gaming console. It is the gaming consoles that best represent the intersection of the three key areas in which the company operates today – electronics, video games, and the entertainment industry.

Impedance

V parametrech sluchátek se setkáváme s pojmem impedance. Jedná se o parametr, který by se neměl podceňovat. V podstatě totiž vyjadřuje to, jak moc dobře - nebo jak moc špatně, si vaše sluchátka budou rozumět se zdrojem zvuku, telefonem, přehrávačem nebo receiverem.

Co to je ANC (aktivní potlačení hluku)?

ANC je technologie potlačení okolního hluku, kterou najdeme v moderních bezdrátových sluchátkách. Využívá sadu mikrofonů, kterými hluk snímá, a uvnitř sluchátek k němu vytváří akustické protivlny, čímž hluk eliminuje. Má ale také určité nedostatky. Jaké? I to se dozvíte v tomto článku.

Walkmany a války o hlasitost

S masovým nástupem kazet se toho v hudebním světě hodně proměnilo. Magnetický záznam audia rozšířil možnosti reprodukce hudby mezi běžné lidi. Ve 20. letech minulého století se objevily magnetofony s ocelovými dráty, avšak ve 30. letech přišla technologie magnetické pásky, která nabízela lepší kvalitu a možnost záznamu více stop vedle sebe.

Jak připojit sluchátka (NÁVOD)

Dříve k připojení sluchátek stačilo jenom jedno zasunutí konektoru. Bezdrátová sluchátka přinesla spoustu svobody, jejich připojení zároveň umí být poněkud ošemetné. V našem článku poradíme, jak Bluetooth sluchátka spárovat například s telefonem, ale i připojit k počítači, televizi či herní konzoli.

Sony WF-1000XM6 (RECENZE): Špičkový zvuk, vylepšené ANC i opět matný povrch. Dokáží si ale celkově obhájit cenu?

Sony WF-1000XM6 jsou zde. Vylepšení oproti předchozí generaci nevypadají jako klasický průměrný upgrade. Výrobce u svých nových pecek klade důraz na aktivní potlačení hluku, ambient sound, kvalitu zvuku, ergonomiku i komfort. Jak je vidíme my?
