The Sharp GX-BT190-BK is the smallest speaker in Sharp's portable range — three and a half inches tall, just over half a pound, with a built-in loop strap for clipping to a bag, a bike or a tent pole. A single 5 W driver paired with a passive radiator gives it more low end than the size suggests, and the 3.7 V 1200 mAh battery is rated at up to 15 hours, the longest in the range. IP67 sealing and a floating design mean it goes into the shower, the kayak or the sand without ceremony. Bluetooth V5.0 covers iPhone and Android AOA devices, True Wireless Stereo pairing turns two of them into a stereo pair, a built-in microphone takes calls, and six LED light modes set the tone.
