Amazon has the X-Mini II Capsule Speaker for only $26.95 shipped, originally priced at $42.13. Unlike its predecessor, the X-Mini II “now boasts a 40mm driver, that delivers an even richer and fuller sound.” Product page.
A brand new feature to the X-Mini II is the “Buddy Jack” system. This allows you to connect one X-Mini II to another and another and… well, you get the picture. Capable of forming a near endless “Daisy Chain”.
