The Pebble V3 is a 2.0 pair of small spherical desktop speakers that take both power and audio over a single USB-C cable. Each has a 2.25-inch full-range driver with a passive radiator, and Creative rates the pair at up to 8 W RMS when fed from a 10 W USB-C or 5 V 2 A source on high gain.
Creative's rating applies with a 10 W USB-C port or USB-C power adapter, or a 5 V 2 A USB-A adapter, with gain set to High; lower-power USB ports give less output. Not a loudness measurement.
USB bus power over the USB-C cable (5 V 2 A or 10 W USB-C port recommended) or a USB power adapter; no battery and no mains supply included
A power adapter and AUX cable are not included. Creative publishes the same USB power specification on its UK and US pages, so there is no mains/plug variant.
Volume control knob and Bluetooth button; H/A gain switch on the bottom of the right speaker
The gain switch defaults to 'H'; Creative suggests switching it from 'H' to 'A' if the connected device cannot power the speakers (crackling). Pressing and holding the Bluetooth button beside the volume control knob starts pairing. Creative's specification table lists 'Controls: Volume'.
Creative publishes only per-speaker weights (left 310 g, right 360 g), no pair or system weight; the per-speaker figures are recorded separately and are not summed.
