Harman has developed a new wireless speaker. According to the manufacturer, the Harman Kardon Go + Play is intended for the demanding listener. The BT-speaker dock has four drivers, dual tweeter midrange and bass drivers with large excursion, as Harman promises. According to the manufacturer, Harman Kardon Go + Play can be connected to up to three devices at the same time. Several listeners could stream their favorite playlists and songs from their own iOS and Android devices. Simultaneous charging of the mobile devices is also possible via USB connection. Harman Kardon's dual-sound capable loudspeakers also allow wireless connections. A stainless steel handle makes the player a portable accessory. According to Harman, the battery lasts up to 8 hours. The manufacturer also praises the device for the telephone conference. Built-in microphone with echo and noise cancelling technology would enable natural sounding conversations even in noisy environments.
