After quietly separating itself from Ultimate Ears, Logitech is finally and once again making portable Bluetooth speakers under its own name. Logitech recently introduced the X300 Mobile Wireless Speaker, the exuberant stereo variant of the company's ultra-small and pocket-friendly X100 offering. Though unlike the X100, the larger X300 is not only a stereo wireless Bluetooth speaker, but has four times as many drivers to help produce richer and more powerful immersive sounding audio whilst still maintaining that highly portable form factor we so very much like. Last week we tested and put JBL's small, albeit very capable $50 pocketable Clip speaker up against Logitech's comparable X100. Although the Clip has narrowly won that battle, we are even more interested to find out if paying an extra $20 is worth overlooking both of these very small speakers in favor of a superior music experience. Better yet, can Logitech's performance-driven X300 Mobile Wireless Speaker beat its Ultimate Ears cousin? Let's find out!
