4 out of 5 eggsWorth the money

Pros: +Great sound for a small speaker set.
+Slick look; cords retract into speaker body and have attached dust covers
+Magnetic storage bindings work well
+Great price for the amount of sound generated

Cons: -USB Mini-F to regular-M adapter is easy to lose, especially if you have kids in the house. Thankfully newegg happens to carry that particular adapter as well.
-Expandable bass chamber is a gimmick, nearly no perceivable sound change.
-Bass reproduction leaves something to be desired, but then again it is a very small driver. Adjusting EQ settings on the source to reduce bass helps.
-No way to use unamplified, like some competitors can. Perhaps in the next iteration (if the manufacturer revises the product) the USB cable will be a female end and the USB socket on the controlling pod will be a recessed male end, thereby making it compatible with most mainstream USB-Mini chargers and eliminating the need for the adapter.

Other Thoughts: Definitely worth the money. They will fill a hotel room, but have realistic expectations for a $25 pair of speakers. I use them with my Xbox-in-a-Pelican Case rig as well as my computer when I travel. I'd consider getting a compact camera case to keep them in when not in use as an added layer of protection, and so you have somewhere to put the charging adapter.
