The SBP1120 is a portable speaker that connects to a device via a 3.5 mm headphone jack and is powered directly from the device, requiring no batteries. The speakers can be placed up to 1 m (3.3 ft) apart to create a wider stereo soundstage, and cable length can be adjusted with the slider on the cable.
The guide includes safety information, such as keeping the product away from liquids and open flames, and a troubleshooting section that advises checking the headphone jack connection and device charge level. It also warns that opening the speaker will void the warranty and provides contact details for online help.
