Enjoy Bluetooth wireless music streaming and party lighting nearly anywhere with the JBL PartyBox 310 Portable Bluetooth Speaker. Bluetooth connectivity also allows you to pair two compatible speakers together, or you can daisy-chain multiple speakers and systems with the 1/8″ input and output. The PartyBox 310 features a 1/8″ audio input for traditional wired devices and a USB input for playback from compatible drives, as well as two 1/4″ microphone jacks, one of which can instead be used as an electric guitar input.
The speaker has two 6.5″ woofers and two 2.5″ tweeters that deliver up to 240W of RMS power. Integrated wheels and a telescoping handle help make it easy to move the PartyBox 310 around, and the built-in battery lasts up to 18 hours. Its IPX4 rating means the speaker has a splashproof design.
