The SRSTP1PK (yeah, not much of a name) require no batteries, as they play simply through the power of your MP3 player. You will probably need to crank the volume pretty high, but the speakers do a fine job so long as you’re in a relatively quiet room. A nice bonus is their ~$20 price tag.

This tiny, miniature speaker includes a protective cover that doubles as a stand when the speakers are in use. There is also a short cable which connects the speakers to the headphone-out on your MP3 player, phone, or other audio device.

Sony’s ultra-portable speaker is available in both pink and black. You can find it at Amazon in:

Pink | Black
