JBL's gigantic portable speakers are now available in the US.
PartyBox 200 and PartyBox 300 are Bluetooth speakers that look like a boombox with two rings of LED lights. The speakers, which were spotted earlier by Android Police, have handles to help you in toting them around. In addition to connecting the speakers to a phone or other device via Bluetooth, you can also program a playlist from a USB thumb drive, and there are inputs for a guitar or mic.
Both products support USB port, RCA, Bluetooth, mic and guitar inputs. You can link speakers together as well. The only difference is that PartyBox 200 needs to be plugged in, while PartyBox 300 has a 10,400 mAh battery that can last 18 hours.
