ENKÊTE

Foarútgong fan technologyen hat laat ta ûntwikkeling fan Bluetooth-koptelefoanen. It hat al dy beheiningen oerstutsen dy't oanwêzich binne yn WI-FI-koptelefoan en Infraread-koptelefoan. In Bluetooth-koptelefoan Radiofrekwinsje kin in hegere radius dekke, mar se konsumearje mear macht. D'r is gjin twifel dat de earcup-koptelefoan de bêste lûdskwaliteit hat. Se hawwe in grut soundstage, hege skieding, en sterke enerzjy, wêrtroch't wy fiele ûnderdompele yn 'e muzyk.
