Sony has rolled out a new line of Bluetooth speakers that come in small, medium, and large.

The SRS-X11 is the smallest of the lot, almost small enough to hang from a keychain, but packs a lot of power in a small package. It supports hands-free calling and has 12 hours of battery life. It comes in five different colors and costs $70.

The SRS-X33 is the medium-sized speaker. It packs 20 watts of power with enhanced bass. Despite its larger size, it still has 12 hours of battery life and is compatible with hands-free calling. It costs $130 and comes in four different colors.

The SRS-X55 is the largest of the bunch. It has all the features of the two smaller speakers but comes with 30 watts of power and a built-in subwoofer. This model also comes in an array of colors and costs $180.

All three speakers are available now.
