Looks like a nice discount. According to PriceSpy this was $119 and has never been lower than $51.75.
Moshi Bluetooth BassBox is capable of creating sound way beyond its size using a passive bass radiator to extend its low-end frequencies, creating deep bass that must be heard to be believed. Connect wirelessly to play music, movies or games from any Bluetooth® enabled smart phone, mobile cell phone, tablet, pad, PC or similar Bluetooth® media player. With an in-built microphone and one click answer button, the Moshi Bluetooth BassBox can be used as a wireless speaker-phone that automatically pauses music when a voice call is received, allowing you to accept loud, clear hands-free calls.
I have moshi hamburger style speakers. They are good. This is probably a good deal.
