We are taking pebble, one of our favorite 2. 0 desktop speakers, and making it even better. Introducing pebble v2, a successor to the popular pebble speaker - we are keeping its minimalistic design, and giving it usb-c connectivity for higher power output. If you are using older computers with usb type-a ports, not to worry, a usb-c to usb-a converter is included for you. Pebble v2 also has a built-in gain switch to help amplify your audio so you can turn up your music and it will still be nothing short of astounding. Speaker features frequency response: 100 hz – 17 000 khz total output power: 8w wired connection: auxiliary 3. 5mm jack cables included: 1 x usb c, 1 x 3. 5mm aux
