House of Marley EM-JA007-BK Chant Mini Bluetooth Portable Speaker
While it might not be as small as some speakers out there, the design is still a very portable option overall. There are a few different Chant models offered by House of Marley, and this one is the smallest at about five and a half inches tall, making it a great choice for setup with a laptop. Sound levels from this are pretty good, thanks to a three watt driver, and it comes with a rechargeable battery, though you only get about six hours of play from a single charge.
House of Marley uses recycled plastic and sustainably-harvested wood to make this speaker, and it ships in recycled packaging, making this the most eco-friendly option on our list. It works with either a Bluetooth connection or 3.5mm audio connection, which makes it a great choice for just about any laptop out there. House of Marley covers this speaker with a two year warranty.
