Basic Specs BlackBerry HS-655
Bluetooth Standard: bluetooth is a wireless technology standard for exchanging data over short distances (using short-wavelength UHF radio waves in the ISM band from 2.4 to 2.485 GHz) from fixed and mobile devices, and building personal area networks (PANs). Invented by telecom vendor Ericsson in 1994, it was originally conceived as a wireless alternative to RS-232 data cables. It can connect several devices, overcoming problems of synchronization.
mono Monaural or monophonic sound reproduction (often shortened to mono) is intended to be heard as if it were a single channel of sound perceived as coming from one position (unlike stereo, which uses two channels to convey the impression of sound coming from different places from left, middle, and right). In mono, only one loudspeaker is necessary, but, when played through multiple loudspeakers or headphones, identical signals are fed through each of the wires into each speaker, resulting in the perception of a one-channel sound, which "images" in one sonic space between the speakers (provided that the speakers are set up in a proper symmetrical critical-listening placement).
