I have to admit that we thought these little X-mini speakers from Singapore’s XM-I were pretty nifty to begin with, but now XM-I says the speakers are going wireless. The X-mini’s are small (around 52mm wide) speakers that can fit in your pocket and be used to pump out the sound to share from your PMP.

When you want to use the speakers, they will pop open accordion-style and product sound with a special bass chamber through a high-fidelity 2.4W speaker. Now, with a limited amount of power we really can’t imagine the X-mini will really be pumping a whole lot of sound, and a wireless version would probably have even less juice but they are still a pretty neat solution.

At only 52mm at its widest point when closed the X-Mini capsule speaker from XM-I adds some serious sound to your portable player in a very compact package. The X-Mini opens up with an accordion-like middle to 54.5mm tall to expose a patented vacuum bass chamber which is designed to “mimic the resonance of a sub-woofer,” according to the company.

It’s also built with s high-fidelity 2.4W speaker to give good sounds in the mid and high ranges as well. The X-Mini connects through a standard headphone jack and also has a USB connection which will juice up the built-in rechargeable battery which lets you share your music with others without the need for an external power source. The pocket-sized speaker’s battery can charge via a DC power source taking 2.5 hours or through the USB connection to your computer …
