Check out this portable speaker from Japan, the UMAZONe. This USB 2.0 powered speaker will deliver 0.35W × 2ch output though a 38mm diameter speaker unit on the bottom. It’s designed as a vacuum tube amplifier with LED flashing lights for a classic and at the same time modern look.
It’s compatible with Windows XP/Vista and Windows 7. The UMAZONe speaker is priced at about $25 and comes in Silver and Black. We’ve seen far worse looking little speakers and you can never go wrong with vacuum tubes.
