10 watts (20 When Paired) of pure tonal bliss. Behind the MATE's sleek black grille rest two 52mm 5-watt high-fidelity speakers featuring NdFeb drivers. These are precisely calibrated for impeccable tonal clarity and high performance at every frequency. From music to movies and beyond, each B–HM MATE delivers 10 watts with more punch than that of more expensive rival speakers. Thanks to an advanced BlueCore Bluetooth 4.0 chipset, all this quality sound consumes little power, affording the internal battery as much as 18 hours of playback per charge. Another nicety: The speaker's battery level indicator appears on iPhone, iPod Touch and iPad
