If you’re the kind of person that likes to share music or videos from your phone, then you no doubt loath the poor speaker that your device was equipped with. It’s not surprising that most such gadgets have poor sound, as there isn’t much room for a speaker. However, these boomCAN speakers might be able to add some strength and clarity to your audio.

These 2.5-inch tall speakers are perfect for tossing in your laptop bag for those times when you want to fill a small room with music. They each contain a rechargeable (via USB) lithium-ion battery that will grant you up to 7 hours of audio. You can even link up two of them together to achieve better sound. Each speaker will set you back $25.
